RE: [Veritas-bu] How to recover data from overwrited tape?
Title: Message hi Jay Well, I am going to stick my neck out here, because reading the sysadmin media manager guide, I dont think it can be done. I dont think the IMPORT process is going to work on this either, as NBU will know about this tape, and its current image contents. The reason why I say this, is because the original data that was on this tape has most likely been destroyed / overwritten with the new data now stored on the same media. Now, in case I am wrong, I will happily be shot down, but just in case, I did find these link, which may or may not be much help. http://www.vogon.co.uk/tape-data-recovery/media-types.htm http://www.disklabs.com/tape-drive-recovery.asp Rule of thumb is, where at all possible, is to not manually expire tapes if you can help it :-( Thanks Simon WeaverTechnical SupportWindows Domain Administrator EADS AstriumTel: 02392-708598 Email: [EMAIL PROTECTED] -Original Message-From: Jay Cheon [mailto:[EMAIL PROTECTED] Sent: 02 February 2006 05:59To: veritas-bu@mailman.eng.auburn.eduSubject: [Veritas-bu] How to recover data from overwrited tape?

RE: [Veritas-bu] Netbackup issues with NDMP restores
Title: Message Hello Sandeen The restores in general work. Unless you have a very old level of ontap and netbackup you should be able to restore down to single files quickly. The magic is that there is something called DAR, this means that you can restore up to 1024 files quickly. If you restore a directory or more then 1024 files in a restore session the DAR feature does not work and the restore process has to pass over the whole backup to finish the restore. This can take a while if the backup was large.

[Veritas-bu] NetBackup Restoration Problem Restoring Millions Of Files
During restores with millions of files, NetBackup saves the restore status to: 1) /tmp/bplog.rest.001 2) /tmp/bplog.rest.002 In which the current (or newest) bplog.rest file is 002, which continually grows, showing the status as each of the millions of files are restored to the server. This file as you can imagine will grow indefinitely with millions of files until the restoration is completed. Is there a way to re-direct NetBackup's bplog restore status to log to a partition OTHER THAN /tmp? NOTE: I am not using the NetBackup Advanced Client, the restore simply spans multiple weeks of data, which is why there are so many files. Thanks, Justin.

RE: [Veritas-bu] Policy Best Practices
Agreed with the Calendar schedule - the way our policies are set, its just easier to simply deactive the weekly policies and enable the monthly.

NetBackup does the smartest thing within a policy and it depends on if you're using frequency-based scheduling or calendar-based scheduling. If you use frequency-based and a weekly and a monthly happen to fall on the same day, the monthly will run today and the weekly will run the next time a window opens. With calendar-based scheduling, you can tell it to ignore certain days for say your weekly and do the monthly backup instead. We don't like calendar-based scheduling very much since it's much, much harder to deal with failures. .../Ed -- Ed Wilts, Mounds View, MN, USA mailto:[EMAIL PROTECTED] ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu This email is for the intended addressee only.

Re: [Veritas-bu] duplication speed
I have 4 drives and am multiplexing things so all drives are in use which i suppose is how i backed things up in 8 hours and yes i gave 2048 set for frag size ( which i've just thought is 2 meg not 2 gig isnt itone to change ) I have worked out the duplication has picked its first image, then mounted that tape and found other images on that and has started duplicating them. What it hasnt done is realize other images to be duplicated ( found with the bpduplicate -PM option ) are on different tapes and then mount them in the other drive. What i have done is to launch another bpduplicate with the -policy flag as i have worked out they are on different tapes than the ones already in progress. I assume when the original job tries to duplicate ones further down the list it will realize a job has already begun to do that.I hope so anyway. The percentage figure jumped from 1% to 6% when it had finished the first tape on the sets it is doing. That still was going to be out of time however as 6% in 140 minutes meant it would take 38 hours for the whole thing to complete.

I am wondering what file num = Surely its not actually a file number and its only written 23 files in 2 hours. Are those 2GB file fragments? If so, that's about right - 46GB in 2 hours or 23 GB per hour - that's better than 5MB/sec.

At 5MB/sec, that's 18GB per hour. To back up 290GB would take 16 hours. I don't see how you completed this in 8 hours unless you were doing a lot of compression. I need the duplications to be finished by > tomorrow and as it has been nearly 2 hours now and saying only 1% > complete im worried it wont be done. Can you estimate the actual speed by how fast it's changing tapes? A DLT7000 is only 80GB compressed so you should be changing tapes every few hours. 290GB in 8 hours is 36GB per hour so that would be a fresh tape every 2 hours tops. > I am wondering what file num = Surely its not actually a file number > and its only written 23 files in 2 hours. Are those 2GB file fragments? If so, that's about right - 46GB in 2 hours or 23 GB per hour - that's better than 5MB/sec. That would put your total time to complete at about 13 hours. .../Ed -- Ed Wilts, Mounds View, MN, USA mailto:[EMAIL PROTECTED] ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
RE: [Veritas-bu] Assistance Required
Justin Your welcome. As Netbackup is going to be the corporate standard, then you may want to make suggestions and evaluate the needs for your clients. For example, if you backup SQL, Oracle or Exchange DB, you are going to require add-ons - which are effectively license keys. These factors are to be considered when pricing up the Netbackup Family. If you have over 300, then chances are your backing up HUGE amounts of Data, most likely in the 20+TB area by now I would hope (or even more!!) Netbackup does allow backups to be carried out across the WAN and through firewalls if the need is required. An alternative would be to implement Netbackup Media Servers. In essence, these are servers that backup themselves locally using a shared tape drive(s). Do you happen to have any of the Netbackup System Administrator guides, as there are some pretty good useful information articles in there that talks about the planning and installation and tuning of Netbackup. As mentioned from the start, I do not know your exact setup, so I can only guide you, but one would think that someone at your site has knowledge of what has been done, and what they are now looking to do :-) Hope this is of some help - again, NOT trying to push you into doing any of the above, just advising you what can be done. In an example here, I have 2 master servers, and 2 media servers, which are treated as SAN MEDIA servers, sharing a larger Tape Robotic Library and backing up the disks through "fibre" channel cards. The reason; To improve the backup performance for our larger systems that holds TB's of Data. You may wish to just implement Media Server or servers at your sites and backup to a tape drive or drives. Wish you good luck Justin. But if you get time, I would strongly recommend doing some research. Not only will this benefit you as the person responsible for the infrastructure, but you also take part responsibility for implementing the kit / software as you see fit :-) Greetings Simon Weaver Technical Support Windows Domain Administrator EADS Astrium Tel: 02392-708598 Email: [EMAIL PROTECTED] -Original Message- From: Justin Durrant [mailto:[EMAIL PROTECTED] Sent: 01 February 2006 11:18 To: veritas-bu@mailman.eng.auburn.edu Subject: Re: [Veritas-bu] Assistance Required Hi Simon Thanks for the response. > Well, bit of a tough question to answer, as there are SO many > questions I would probably want to ask you, one of them being "Is > Netbackup the product > for you" !?

Our remote sites use a variety of solutions. Ideally, you would make a server at the remote site a media server and hang a tape drive off of it. The catalog would still be on your master. We haven't had approvals to implement this yet so we're using a couple of different approaches - BackupExec with local tape drives, or storage replication back to our central offices. > > Are they a variety of operating systems?

This isn't the wrong way. Think of the SAN as just an expensive RAID controller. If you want to bypass the file system in any way, you're not going to be able to restore individual files. There are various approaches to backing up SAN-connected hosts faster than a traditional host-based backup (SAN media server, off-host backup) but you're still going to be talking to the client that is using the storage. You can also minimize the impact on the client by using snapshotting technologies, whether it's on the SAN or at the host level. > > In terms of what you backup, you may be able to find this out from the > > "Images on Media" report tool - most of the information about the clients > > and size of data on tape can come from the Reports applet. > Thankyou, I'll take a look at these reports. There are various commercial NetBackup reporting products that can help you do capacity plannning. We use Aptare's StorageConsole. With NetBackup 6.0, there's NetBackup Operations Manager that gives you a subset of that functionality. There are other products out there too. You can write scripts that generate reports for you on the master server, but if you're the only person only somewhat supporting an environment with over 300 clients, you're probably not going to have time for this. > > Netbackup is scalable, there is no doubt about that - In my own personal > > view, some of the add-on's appear to be very expensive (ie SQL license, > > Oracle) so you need to take costs into account. > Phew, that kinda answers part of the issue.

We have half the number of clients you do, but we have a lot of storage tied to our clients - our SAN alone is about 150TB and growing exponentially. We're using a combination of normal filesystem backups and SQL agents, Oracle agents, Exchange agents, and flash backups. We hope to add Bare Metal Restore functionality later this year. > > Not sure if I am being much help here ? :-( > Any help is more than I had to start with. Thanks muchly If you've got specific questions, just holler. There are consulting companies out there that can help with NetBackup capacity planning and tuning (for a fee of course). We had Datalink come in last year to help us evaluate our environment.

[Veritas-bu] duplication speed
People i am moving an infrastructure from one site to the other. As part of this we are splitting things between different trucks for resilience. I performed a full backup of the infrastructure yesterday and today am duplicating it. I run solaris 8 Netbackup 5.0 mp5S2. I am slightly concerned as it reckons the job is only 1% through on the gui. When i run iostat -xn |egrep "rmt/0|rmt/2" i can see around 5mb/s which is about right for the DLT7000 drives i have in the L1000. There are 32 images in total to duplicated and the backups took around 8 hours to complete 290 gig. I need the duplications to be finished by tomorrow and as it has been nearly 2 hours now and saying only 1% complete im worried it wont be done. Looking in the bptm logs i can see entries like this :- 12:04:15.737 [307] <2> io_write_back_header: drive index 0, clienta_1138722148, file num = 23, mpx_headers = 7, copy 2 12:04:15.737 [307] <2> io_write_back_header: drive index 0, client2_1138722153, file num = 23, mpx_headers = 6, copy 2 12:04:15.738 [307] <2> io_write_back_header: drive index 0, client3_1138722154, file num = 23, mpx_headers = 5, copy 2 12:04:15.739 [307] <2> io_write_back_header: drive index 0, client4_1138722155, file num = 23, mpx_headers = 4, copy 2 12:04:15.740 [307] <2> io_write_back_header: drive index 0, client5_1138722156, file num = 23, mpx_headers = 3, copy 2 12:04:15.741 [307] <2> io_write_back_header: drive index 0, client6_1138722157, file num = 23, mpx_headers = 2, copy 2 12:04:15.741 [307] <2> io_write_back_header: drive index 0, client7_1138722158, file num = 23, mpx_headers = 1, copy 2 12:04:15.742 [307] <2> write_data: completed writing backup header, start writing data when first buffer is available, copy 2 12:04:15.742 [307] <2> write_data: first write, twin_index: 0 cindex: 0 dont_process: 1 wrote_backup_hdr: 1 finished_buff: 0 12:04:15.742 [307] <2> write_data: received first buffer (64512 bytes), begin writing data I am wondering what file num = Surely its not actually a file number and its only written 23 files in 2 hours. I used the below for the duplication as the backups are multiplexed. bpduplicate -dp dupe_monthly -dstunit L1000 -hoursago 22 -sl Monthly -mpx -L /var/log/move-dupe.log & Is it worth be canceling and just doing another full backup or do people think the duplication will complete?

I dont believe I have a choice in this as we already have this in place. > How many client machines are you backing up? Over 300 hundred boxes. Most of them are on site locally but there was mention that perhaps we should be backing up our various remote sites.

I'd like to be able to backup the SAN data directly; it is currently being backed up via the machine that uses the space but I'm sure that this is the wrong way to do it. > Is Netbackup going to be the corporate backup product and part of your business strategy?

RE: [Veritas-bu] Assistance Required
Justin Well, bit of a tough question to answer, as there are SO many questions I would probably want to ask you, one of them being "Is Netbackup the product for you" !? How many client machines are you backing up? Are they a variety of operating systems? (ie: Unix, NT, 2003) Is Netbackup going to be the corporate backup product and part of your business strategy? In terms of what you backup, you may be able to find this out from the "Images on Media" report tool - most of the information about the clients and size of data on tape can come from the Reports applet. Netbackup is scalable, there is no doubt about that - In my own personal view, some of the add-on's appear to be very expensive (ie SQL license, Oracle) so you need to take costs into account.

RE: [Veritas-bu] NetApp/NAS - Backups
Funnier,,, judging by the BakBone compatiblity guide,, dynamic drive sharing doesn't seem to be a supported function in versions of DOT greater than 7.x. Now who do you think the issue is with? I think it is with NetApp as in 7.0+ they probably implemented persistent bindings as an enhancement.

Re: [Veritas-bu] HP LTO 3 Ultrium & WIN2K03 NBU Optimization?
If you look back in the list archives you will see this explained. HBAs and SCSI cards that use the windows miniport driver have a 64k limitation set by the maximum_sg_list parameter - or rather its default value as it is usually not defined. You can raise this in the registry settings for the particular driver, up to a maximum of 1MB. Search the internet for the sg_list or 'scatter-gather list'. 256k is consistently reported as the best size for LTO by all LTO vendors. HBAs that don't use the miniport driver usually don't have this restriction. Note that HP use the miniport driver with Emulex OEM'd HBAs, where the native Emulex driver is a port driver. So you can have the identical hardware behave differently. Always check you can restore data where you need to. If your DR site is limited to 64k by the drivers there, backing up at 256k will hurt.
