Re: continuous backup solution for FreeBSD
I just wanted to say thanks to all the replies to this thread. It has been insightful even though the suggestions I have received were not really answers to what I asked. I dont see any reason why we should continue to argue about if this can be done using ZFS or Hammer or any other filesystem. The fact is that it can be done eventually with something else if one has the will, time and money to put into it. One can even write his own filesystem code for it eh? The original question (which was lost) was if somebody who has technical knowledge and coding skills who can put r1soft into the right track so their software can support FreeBSD. Because r1soft is interested in supporting FreeBSD. Most of you probably know that FreeBSD support in products of commercial companies are scarce already. This is causing reductions in user base and popularity, although I am not saying that the more users are the better or I am not saying that popularity is everything. But you have to be able to combine one issue with another and see what the results might be in the long run. For example, wouldnt it be good for FreeBSD itself if Oracle supported FreeBSD? While I cant make Oracle to support FreeBSD, there is a company out there with a popular and quality product which is interested in supporting FreeBSD in their products. So why not take advantage of the situation? While I didnt think about some details when I sent the first post, some people thought that I would want somebody to code for r1soft for free so they can sell the software. No I do not and did not expect anybody to do anything for free. So, to summarize, if there is anybody who wants to help the 'actual' issue here, either by getting payed or just giving free hints and tips to r1soft then please contact me (I can forward your contact info) or with r1soft. Dag-Erling Smørgrav already told me that I can send his info and I have sent his contact info to r1soft for this issue. I hope we can now stop arguing about all the other things :) It wasnt my intention to start such arguments.

As you can imagine, it is not only important that data can be restored when a box hardware failure etc. it is also important that data can be restored if deleted by accidents etc. While traditional backup programs provide this functionality, you cant really go back to 10 min or 1h ago, often they take daily backups and have to scan whole filesystem for changed files every time the backup is taken which stresses out the systems. This can (more or less) be achieved with snapshots: you can cheaply maintain old versions of the file system, and mount an old snapshot at any time. Hourly is about as fine-grained as you can expect though. The documentation says one cant do more than 20 snapshots. http://www.freebsd.org/doc/en/books/handbook/snapshots.html Although 20 could be enough combined with a normal backup program. As far as I understand creating snapshots will consume disk space, and freeze the disk writes for a certain amount of time, every time (I read 5 seconds for 8GB system http://www.wave2.org/2007/10/08/mysql-snapshots-on-freebsd/ ) snapshot is created. The snapshots are stored in the local filesystem and it would require manually transferring the data to a remote machine. More importantly, as far as I understand, if the hard drive totally fails, there would be no way to restore a snapshot anymore unless we have a dump of the whole filesystem and first restore it and make sure everything is exactly at the right blocks in the drive. No? Although this probably could be worked out. In my opinion it requires a lot of work, Bbt thanks for the advice. Just that I would rather pay a small amount of fee and use Linux and use a continous backup software which works as easy as install and run. Which also provides utilities for easily recovering files or the whole filesystem or disk. Thanks again for pointing out snapshots. It is more or less suitable :) Thanks, Evren ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]

Wow... thanks for the flame, but there's no reason that the device that is receiving the hammer replication couldn't be on the other side of the globe and there's no reason it couldn't be considered a backup. Part of the advantage of the structure that allows you to efficiently select for new changes allows you to do the same kind of *backup* as they claim. Wouldnt that device need to keep the whole filesystem?

Re: continuous backup solution for FreeBSD
I think here might be a misunderstanding. I was talking about a reliable backup solution whereas you guys are all the time talking about mirroring and replication type solutions. Since you cant be thinking that mirroring and replication can replace backup, there must be a misunderstanding? Zaphod Beeblebrox wrote: From my reading, Hammer is much more than a filesystem, but then you probably havn't read about it yet. By my reading, Hammer hits all their feature points and does it better _because_ it's a filesystem. I glanced through these actually: http://www.dragonflybsd.org/hammer/ I didnt see anywhere that it will replace backup programs? It's relatively simple. Database replication solves the data backup problem (I don't store application data outside the database). Database replication for both MySQL and PostgreSQL is relatively straight forward. As for the configuration of code and servers --- that is taken care of with configuration management (it's really a bigger issue than just backing up a filesystem) and installing a new server to take a place in the cluster is a straight forward checkout from the CM system. For things I really care about staying up, add VRRP and an application design that is fault tolerant. Have you ever tried to restore data from MySQL replication logs? :) Even if you use binary logging, when you want to go back in time. You will need to first restore the whole database first from normal backups then replay the logs until the point that you wanna be. There is no simple way to go back in time. That is of course you have backups. If you dont have backups because you think replication is a backup solution, you would be screwed. Totally more complicated that clicking from the web to select data and time and table and restore! Also, you are thinking about a very small sized system. While replication might work if you are relatively small sized company (like 1-2 servers). If you have many independent servers with different databases inside you just cant use it. Even if you could replicate multiple boxes into one box, there would eventually be problems such as same named databases etc. and even then, you cant just easily restore the data if the user deletes all his data in his tables. Also that is not practical for users at all. For example I cant give an option to the user to restore his data by himself. While that is possible with most backup software easily. About VRRP etc. I already told that I am not talking about redundancy here. You are talking about totally different things. I need data protection. This actually works rather well if you do your research. Database replication is possible at all kinds of different link speeds and distances. Database replication also allows you to control your data better --- you know more about your data than a block replicator would. It means that your backup is already live and it means that, with the right scripts, invoking a backup on primary failure is simple. Database replication on some databases even allows you to preserve transactions --- which is important in some cases. And how do you propose that I restore a table in the database to of 1h before status? like you can do with a data backup solution? You are talking about a spare server solution not backup solution. Replication IS NOT backup. If you look at articles and information about database replication, almost all mention that it DOES NOT replace backups. Well... no. Backup software and strategies are just one available tool for risk mitigation. To know what tools you require, you must define your risks. Then with your list of risks you look at the cost of each tool and find the toolset that suits you. By the responses in this thread, it seems like the set of FreeBSD developers and the set of people who desire this solution are disjoint. Right, I just cant use the tool I require. There is no way to take near continuous backups of FreeBSD filesystems. Actually... as some obligatory positive content, the time travel features of Hammer should be straightforward to implement in ZFS... are ZFS modules supported on FreeBSD yet? It would seem to be a logical module. Those features work within the filesystem, you there is no mention of mirroring to a remote hard drive, if you could mirror to a remote hard drive, you couldnt easily mirror 10 machines into 1 remote hard drive, even if you could do that, it would require total disk space of all those 10 drives to exist in that 1 backup server. Even if you could overcome that, this would mean that all FreeBSD users wanting to take advantage of such system to convert their filesystems. Even if it was easy enough, there is no GUI tools to allow users exist in those systems to restore files by themselves easily. As you can see, none of the solutions you are suggesting is anywhere near simple solutions which can replace near continous backup
continuous backup solution for FreeBSD
Hello, As far as I can see, there is no continuous backup solution for FreeBSD at the moment. I talked with R1Soft and they seem to not be able to support FreeBSD and need help. Does anybody have free time and skills to give a hand?

FreeBSD is loosing users because of this issue. gmirror+ggate come to mind as a nifty solution ... That allows mirroring however not a very practical solution. You would need to mirror every drive in another machine and you cant restore the drives into a earlier time. I am talking about a real backup solution where the backup agent collecting the information about written sectors and sending to backup server. You can then restore a file which existed in the box 1 hour ago if you need to. For example think about a situation where a server is processing important data which shouldnt get lost. A software failure wipes out the hard drive. You would loose all the data in the mirror as well. Also the setup of such mirroring system would be rather complicated. In addition to that, the mirroring does not support for example restore of mysql databases in table level. Think about a customer who wiped out his database accidentally. All the data would be gone in the mirror as well. With near continuous backup you can restore the data to just moments before the deletion process. Traditional backup systems at best daily backups, even if you could restore the data, the data could be up to 1 day old. More on that subject, r1soft supports multiple hosting control panel softwares. For example H-Sphere ( http://www.parallels.com/hsphere/ ) etc. through plugins which allow hosting customers to restore their own data easily. Something impossible with gmirror+ggate combination (since it does not actually backup the data and only mirror it) and not even practical if it was possible, if you have thousands of users. Actually, I am not saying that anybody should be doing about this and neither am I an r1soft advocate. I am just pointing out that there is a company out there which can provide a valuable software tool and they need somebody to put them into right direction only. If you know some FreeBSD developers who know the disk subsystem and can help R1Soft then you can perhaps forward this information to them. This not a feature or help request and I just am mentioning this. However you can imagine that a company which is giving online services on a serious scale probably would be interested in a CDP solution. It is currently impossible with FreeBSD. This makes using FreeBSD servers on critical applications a little bit insecure data protectionwise thus often people prefer Linux which is supported by such continuous data protection type backup solutions.

Keeping a live filesystem replicated does in no way guarentee that your database (for instance) will be sane at any particular moment. It sounds like these guys have made allowances for MySQL (they specifically mention it), but this won't help the PostgreSQL users, etc. I think you didnt get the point here.

Wrong term: Even open source folks need something for living. That's too cheap and I don't suggest supporting a company like this, as they're expecting somebody else to do their job and make profit of it. They're free to use a system like FreeBSD for their products, they're free to modify and redistribute it but they need to do their job and don't expect anybody else to code for them for free. I agree, perhaps whoever can help than can ask for money for the job done and I am sure they would pay reasonably since this is a commercial company. But as far as I can see people here do not even know the difference between near continous backup and mirroring. I just wanted to inform that there is such solutions nowadays available but FreeBSD users are not able to take advantage of them and the company who is making the product is interested in supporting FreeBSD but perhaps somebody who has experience can give some hints to them. They actually do not think that it is an easy job to adapt their software to support FreeBSD even.

A good read. You can go ahead and explain it to r1soft or any other software company which makes near continuous backup solutions. So maybe they can find this information and improve their product. So far at least this company thinks that this is impossible to do with FreeBSD as far as I can tell. I know people who want to switch to using FreeBSD but cant do that because their backup solution (R1Soft) does not support FreeBSD :( What's wrong with solutions like Bacula? It's working, cross platform, well supported. Do you know what is near continuous backup solution or ever heard of such technologies? I dont see how you can compare this with Bacula. They are not the same thing really. I can tell you one thing which is wrong with Bacula, it scans the whole filesystem everytime it takes a backup even incremental backups (while this disk io loading operation is unnecessary with CDP), and Bacula cant restore your data to what there was 10 minutes ago at any time of the day. And now, go ahead and flame me for not doing work for free for other peoples profit but I'm pretty sure there won't be much guys wanting to do that. There is nothing to flame or blame really. I can only blame my own stupidity. I posted this information here in hopes that somebody capable can give some hints to r1soft or to another near continuous backup solution so we could all benefit. But what do I get? All I get is information about solutions which mirror / replicate the data or suggestions of standard backup programs. I am not even surprised that FreeBSD is not supported. FreeBSD users do not even know the difference between a CDP solution or mirroring / replication or traditional backup... Go figure... If you dont know what is CDP then please read and learn (there are links to wikipedia articles in this address also) http://www.r1soft.com/CDP.html I never told that anybody should make the software ready for selling by another company for free, neither the post in the thread is asking for somebody to write a driver for free. The company obviously understands that such job requires an expert who works for money. They probably wouldnt mind if somebody wrote it for free to them (who wouldnt) but it doesnt say that they wouldnt pay. If you can do the job, please contact the company and give your price. If they tell that they want it done for free, then come and complain that they want it done for free.

While your post was vague, I read the company's website to I am sorry what was vague since I wrote 'continuous backup' in my post? The whole idea is such a basic idea that if you put this to google you can get wikipedia entry about it in first 3 results (I see in 2nd). Maybe you didnt know anything about it makes it vague to you. The message I sent was quite clear and plain. determine the featureset they were claiming (although I missed their postgres support --- I only read the features page). NetBSD's hammer filesystem achieves replication at the filesystem layer (which will do infinitely better at this problem than a block-only driver) by maintaining a history of what's happened and being able to select (as in the database term) changes to the filesystem that have occurred since the last batch of blocks were shiped out to replication. This gives you both fine grained recovery (basically changes to files are kept until your rules define they should be freed) and replication and fine grained recovery on the other side of replication. In fact, Hammer delivers what they claim in a far more sophisticated way. You might want to read this page too: http://www.r1soft.com/CDP.html (but it's NetBSD, not FreeBSD, unless someone decides to port it) While Hammer might be doing a similar job, it is a filesystem not a backup application and it wont replace backups. It doesnt just store the data in a backup server. While eventually it might become a backup solution, it will take years before that can happen. Even then, people will not just switch their current filesystems overnight. The CDP backup softwares are available today, it just needs a sort of driver to function in current system. Also they support postgresql as well (while its usage is way smaller than mysql) http://www.r1soft.com/CDP_db_postgreSQL.html In any case, the product guarantees that it can return your databases to any point in the time. Do you see what you are missing? :) Well... I am not missing it. I have that without making my filesystem jump through an enormous hoop. But designing my application correctly, I have that feature for far less effort. (that was the other point of my post) Can you just explain how can one currently do that in FreeBSD? Is it as easy as in Linux with CDP backup softwares? such as installing a program and done? I've spent a lot of time thinking about redundancy and I've come to one inescapable conclusion: That the further up the stack you design for redundancy, the cheaper and easier it becomes. Most databases have replication strategies of one type or another that don't require exotic hosting solutions to work. The idea/problem is not redundancy here, it is data protection. Well... no... you don't need fine grained filesystem history for data integrity (unless you let loose a bunch of summer students armed with the ability to RM or your application is faulty (in which case, your filesystem won't protect you). As I said, This can all be achieved with other far simpler solutions. However, if your dev team isn't smart enough (or don't care for some reason), then you can take advantage of their product and pay their price. There is no perfect system. This is exactly why people take backups. If what you said was applicable then there wouldnt be any need for backup software. People would just make sure that they dont loose their data. In addition to this, I have no control of if my customer will delete his/her data accidentally. I cant make a system which does not allow customers to delete data. I have given an example of a simple solution that Linux users can utilize (which obviously we also can utilize if we put our heads into it and give some directions as r1soft is willing to support FreeBSD). While you are first saying that these can be achieved with far simpler solutions, at the same time you are saying that the dev team must be smart enough. My solution is simple enough to write here.

Whereas this single process works really slow if the system is already at the slowest speed. Is there a simple way to fix this problem?

Hi, I remember from earlier versions of FreeBSD that it had a restriction about alias IP netmasks (somewhere in 3.x,4.x days)... as explained here: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/configtuning-virtual-hosts.html - The calculation of alias netmasks is important, but fortunately quite simple. For a given interface, there must be one address which correctly represents the network's netmask. Any other addresses which fall within this network must have a netmask of all 1s (expressed as either 255.255.255.255 or 0x). - However I tried on the loopback interface to add a 2nd IP with the same netmask as the original IP and it accepts it fine. (on 6.2) lo0: flags=8049UP,LOOPBACK,RUNNING,MULTICAST mtu 16384 inet 127.0.0.1 netmask 0xff00 inet 127.0.0.2 netmask 0xff00 Is FreeBSD allowing this a bug or ??? If this is not a bug. What happens if an interface which is connecting to the machine has 2 IP addresses with same netmask which is not 255.255.255.255? Does FreeBSD use each IP randomly?

any plans to enhance 'locate'?
Hi, I am wondering if there are any plans to enhance the locate command. As you know, Linux slocate is storing file owner/perm info into database and it is able to show all files when the user is root compared to FreeBSD locate where you can only search files which can be listed by nobody user. I realized that this comes very handy when I am looking for certain files if I can see the files owned by root 'only' when I am root. Is there a reason why there is no port for slocate or the FreeBSD locate to not to be enhanced this way? There seems to be a port for this for Mac OS X: http://slocate.darwinports.com/dports/sysutils/slocate/ There are people trying to do workarounds: http://freebsd.munk.me.uk/archives/207-Let-root-see-all-files-with-locate.html Thanks, Evren ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]
jail cpu/memory resource limits question
Hi, FreeBSD supports jail cpu/memory resource limits. http://wiki.freebsd.org/JailResourceLimits I hear that these are very inefficient (compared to FreeVPS for example) and with over 1000 processes it creates noticable overhead. Is this true? Thanks, Evren ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: logitech cordless optical mouse problems...
Yes, but the keyboard mouse I mentioned is working without any resets in Linux and Windows. So it cant be faulty hardware Evren On Wed, 31 Dec 2003, Peter Dufault wrote: On Dec 30, 2003, at 11:31 AM, Evren Yurtesen wrote: The funny thing is that this works in Windows and Linux.

I've used one on FreeBSD in the past, and it would work for weeks, and then the mouse or the keyboard would stop working even through reboots. I had to go through combinations of resetting the logitech hardware to get it to work again. I found the sequence on Logitech's website, it was something like reset all three pieces, unreset the wireless part, then unreset the keyboard and mouse. I'm currently using this mouse/keyboard on a Windows system. I have to unplug and replug the USB connection after the system powers up to get Windows to find the mouse, at first it powers up only with the keyboard. 100% reproducible. I have a newer version and don't have any problems.

logitech cordless optical mouse problems...
This mouse has a USB connection and PS/2 connection to the computer. The keyboard works but the mouse doesnt.

That is not the problem. I get nothing freebsd:/home/staff/yurtesen#cat /dev/ums0 its empty But this is a weird mouse, it has USB connection and then PS/2 connection also. It doesn't work if the PS/2 connector is not connected! I was thinking that the mouse maybe shows itself from USB but communicates through PS/2 connector.

Re: logitech cordless optical mouse problems...
If I plug out the USB portion, then I cant use the keyboard anymore! But I will try plugging out the PS/2 section, then send email again. The funny thing is that this works in Windows and Linux. So how come it doesnt work in FreeBSD without any physical change? I think this is a bug in FreeBSD. Also I wonder if it is possible to use the normal ps/2 keyboard and the wireless usb keyboard at the same time? This also works in Linux and Windows. I know that I can change the keyboard in use by changing the devices from kbd0 to kbd1 etc. But in Windows and Linux both keyboards work simultaneously without any change.

Re: logitech cordless optical mouse problems...
OK My mistake the mouse works only with USB connection (in linux!) I couldnt test windows but I suspect it would work there too. The funny thing is that only with PS/2 connector connected. Nothing works in Linux either. I cant even type at boot time. Well its not that funny after all. But I dont know what is the purpose of PS/2 connector anymore. There is a mouse icon on it though ...

bind and the limit of serial number ???
Hello, is the bind have 32 bit unsigned integer variable for the serial number part of the dns records? if yes, it means that we cant have a number bigger than 4294967296 right? what happens if we have a bigger number? then bind takes it like modulus 2^32? or it is forbidden to have a bigger number?

Re: bind and the limit of serial number ???
well ours is still working fine ! thats why I asked this question, we did not realize that it went over 32 bit boundary how can I understand if there is a problem or not?

Re:(2) hey
Well, I am the person who has this problem. The RFCs does not explicitly say that we should not use underscore character as far as I understood. But it suggests which characters we should use. Also in RFC1033 it says (well the status of this one is UNKNOWN though) - The domain system allows a label to contain any 8-bit character. Although the domain system has no restrictions, other protocols such as SMTP do have name restrictions. Because of other protocol restrictions, only the following characters are recommended for use in a host name (besides the dot separator): "A-Z", "a-z", "0-9", dash and underscore - So Solaris does the right thing by understanding underscore I guess. Since it is not forbidden to use it in hostnames. http://www.crynwr.com/crynwr/rfc1035/rfc1035.html#2.3.1. - For example, when naming a mail domain, the user should satisfy both the rules of this memo and those in RFC-822. When creating a new host name, the old rules for HOSTS.TXT should be followed. This avoids problems when old software is converted to use domain names. The following syntax will result in fewer problems with many applications that use domain names (e.g., mail, TELNET). domain ::= subdomain | " " subdomain ::= label | subdomain "." label label ::= letter [ [ ldh-str ] let-dig ] ldh-str ::= let-dig-hyp | let-dig-hyp ldh-str let-dig-hyp ::= let-dig | "-" let-dig ::= letter | digit letter ::= any one of the 52 alphabetic characters A through Z in upper case and a through z in lower case digit ::= any one of the ten digits 0 through 9 - BTW.
