Re: Restoring from tape when Amanda server failed - conclusion and open questions
Thanks much for the support. Eventually I was able to restore some of the missing files but I still have some open questions. 1) I was able to restore the files on the Server where Amanda server was initially installed. However, I could not restore the tape from a different server (ServerB) with similar operating system (Solaris 9). The mystery about the restore process was that I successfully run the commands(on serverB):a. mt -f /dev/rmt/0cn rewind b. mt -f /dev/rmt/0cn fsf 1 But when I run the command:dd if=/dev/rmt/0cn bs=32k skip=1 It gave me the following error message: read: Invalid argument 0+0 records in 0+0 records out Does anybody know why?
2) When I restored the data using the command: dd if=/dev/rmt/0cn bs=32k skip=1 | gzip -d | /usr/sbin/ufsrestore -ivf - I was only able to restore files that were saved - level 0 on that particular tape; Yet I also restored a folder on Amanda that folder was lastly restored on run level-1. But need to restore certain files from that folder without restoring the whole folder is this possible using the ufsrestore tool? In the past I was able to do so

Restoring from tapes
hi, We have a Solaris server that runs multiple applications including Amanda server. This server is connected to a tape drive were the backupfiles are being stored (by Amanda).So far, data is stored and successfully recovered from the tapes. However, what can be done in case the Amanda server is crushed? Are there indexes on the server that enables the restoration or can I restore the files from a different server? What is the best practice to prepare for such event?We have a new Solaris server that can be connected to the tape drive as well. Should I install Amanda server on that new server to prepare for a disaster on the main Amanda server? Any suggestions comments are mostly welcome. Many thanks, gil
to configure or not to configure this is the question
Hi, We have Amanda backing up our Solaris servers for about a year. So far we are very happy with Amanda. Recently I was requested to use Amanda to backup some of our Window server. In order to do so, I have to configure Amanda with Smbclient. Does it mean that I have do reconfigure + make + make install from start or is there another way more graceful to add the Smbclient configuration to Amanda. Many thanks, Gil

Amanda - unable to create temporary directory
Hello, Amanda is successfully running on our Solaris Servers. But on Amanda's report (the E-mail it sends after amdump) I get the following STRANGE message: ? Unable to create temporary directory in any of the directories listed below: ? /tmp/ ? /var/tmp/ ? / But when I manually accessed the server as Amanda user - I had no problem creating a folder under /tmp as well as /var/tmp/ !

Switching to GNUTAR - RE: Amanda - unable to create temporary directory
Thanks for the help, At this point it seems that the best way for us is to switch from ufsdump to gnutar. But before doing so - what will happen with the backups that I did so far? (I backed our data on a tape drive). Does ufsdump and gnutar stores the data the same way? (Does ufsdump level 0,1... is identical to gnutar level 0,1...) Or does it store the data on a different format? Does Gnutar is going to store the data twice or is it going to overwrite the data that was stored by ufsdump? Any other concerns that I should keep in mind before switching from ufsdump to gnutar?

We had this problem every night on one specific solaris 9 system, and no other sol9 or sol8 systems (and our amanda client is installed via a package, so it's the same across all machines). The solaris boxes are also installed from the same jumpstart images, so they should all behave the same. This error comes from ufsdump, and near as I've been able to tell, ufsdump is creating a directory named something like '.rlg.zyaaGR in each of /tmp and /var/tmp (and failing to be able to in / since it's not running as root, the jibberish after .rlg. changes with each run). This directory is called with mode 000 and then ufsdump attempts to create a file in it, which fails and generates that error message. I wasn't able to get ufsdump to behave better (nor did I look for a patch or try to reset ufsdump to being setuid again) but on that specific system we had amanda incorrectly configured to backup something other than the mountpoint of the filesystem, but something inside the filesystem (that is, instead of /export/home it was /export/home/foo/bar where the filesystem was mounted on /export/home). Switching this to the mountpoint made the error go away. There may be some limitations in ufsdump that cause you only be able to use ufsdump this way if you're root (though sounsd lke a bug). If you're doing this, and doing it on purpose, I'd suggest using gnutar instead of dump since incremental dumps don't work right except on filesystem boundaries. If you're not doing this and actually backing up a mountpoint, then maybe the above info will help track it down. (perhaps the setuid bit, as Jon suggests). -Todd

amrecover + build in security protocols
Ok, so I have started deploying Amanda to backup our local Servers - but I want to start deploying it on the remote servers. Amanda Server is one of our Solaris machine. This machine is also Amanda client - being backed up by Amanda. I was able to backup data to it and recover it with Amrecover. But what happens if this Server crashes?? How can I recover data from the tapes? Additionally, I am thinking to deploying Kerberos over Amanda and it might take me some times to figure it out. In the mean time, I read about Amanda that: It was designed with data security in mind. It uses its own network protocols, so it does not suffer from the security problems. Does anyone knows what kind of network security it has? Thanks, gil

Hello and thanks,
So it turn out that my suspicious were correct.
After rerunning amtapetype twice on our Solaris 9 server I got the
configuration for Ultrium2-LTO slightly different and with the new results
amlabel worked fine :)
In the first run I got the following result:
define tapetype unknown-tapetype {
comment just produced by tapetype prog (hardware compression off)
length 207465 mbytes
filemark 939 kbytes
speed 17489 kps
}
But Amanda could not identify my tape drive.
In the second run I got the following results:
define tapetype unknown-tapetype {
comment just produced by tapetype prog (hardware compression off)
length 206819 mbytes
filemark 918 kbytes
speed 17477 kps
}
which worked fine.
Anyway, I'll publish the results for the Ultrium-LTO2 tape drive on Amanda's
website.

Add an estimate value! And it takes about 5 hours only. Without
an estimate it takes a week or so. Like this:
amtapetype -f /dev/rmt/0n -e 200g
On the other hand, writing a few bytes is enough to see it the drive
works.
About the problem: you did specify that device in your amanda.conf ?
(I believe that was what Gene was hinting about.)
Chuckle, yup. Sometimes I get my tongue tangled up with my eyeteeth,
and can't see what I'm writing... Corrections in that case are
always welcome. :-)
With the ultrium it is less important about considering HW or SW
compression. But be aware that on Solaris whether HW compression
is turned on or not is determined by the device you choose. You
will find lots of /dev/rmt/0xyz devices. The xyz determines
the properties of the device the driver will set upon opening it.
Don't be fooled into assumptions about the various devices. The
c device is listed as compressed. But that is the conventional
use. There is no certainty that it turns compression on for every
device, or that devices without the c are no compression. You
will even have a c device for drives that are not capable of
HW compression ;-) Only way to tell is check the docs for the
drive and settings for the driver. And then I'd check it if I
could.

Anyway, I'll publish the results for the Ultrium-LTO2 tape drive on
Amanda's
website.
And what kind of bug have you found, as the subject seems to imply?

Amanda security with Kerberos
hi, I am a little confused regarding adding security to Amanda. In the past I posted a question regarding adding security to Amanda - We have a Solaris 9 machine which is Amanda server and a remote Solaris 9 machine which is Amanda client. We need the data that is transferring from the client to the server be secure. People have kindly answered my question but I am still confused. Some have suggested to use sftp or ssh - bring those files to the server and then backing it up locally. However, by implementing this technique I am over loading the network - because I have to ssh or sftp all files daily instead of letting Amanda get only the changes (level 0,1 etc). But is there a way to implement ssh/sftp with Amanda? Anyway I am trying to implement Kerberos and I have a few questions about it. I am trying to follow the documentation in Amanda for kerberos - so far I downloaded the file amanda-krb4-2.4.0p1.tar.gz - I unzipped it and tared it (tar xvf). Yet I don't know what the next step should be - configure+make??? Additionally the KERBEROS doc for Amanda under the INSTALLATION section says: 2. INSTALLATION The kerberized Amanda service uses a different port on the client hosts. The /etc/services line is: kamanda 10081/udp Then what should be the host on the server site? Finally how can I test that Kerberos encryption works with Amanda? Please note that our Amanda server and client are Solaris 9 boxes but in the future we might implement it on Win boxes (is it feasible to implement Kerberos on Win box?)

AMLABEL
Hello,
We have a new tape drive but I am unsuccessfully running amlabel.
Some background:
I was successfully running amlabel on HARD-DISK.
I modified amanda.conf file to accommodate the new tape drive
specifications:
I added the new tape drive spec - which I got through running amtapetype.
with the following :
define tape type ULTRIUM2-LTO{
comment just produced by tape type prog (hardware compression off)
length 207465 mbytes
filemark 939 kbytes
speed 17489 kps
}
and added the following line in the 'main' section in amanda.conf
tape type ULTRIUM2-LTO
But when I run the command:
# amlabel DailySet1 DailySet1001
The system ask me:
#insert tape into slot 1 and press return
Even though the tape is already in! - I tried to eject and insert the tape
but it again requested me to insert a tape!
Is it because Amanda could not identify my tape drive?
Or maybe it is related to my previous testing of Amanda with our hard-drive.
I successfully labeled our hard-drive and recently I comment it out and
labeled the new tape drive?
Thanks much,
gil
FW: AMLABEL
The Operating system is Solaris 9
and tape drive is under /dev/rmt/0n which is the defualt for Solaris.
Thx,
gil

RE: AMLABEL
Gene - thanks for trying to help,
Currently the only reason that I can think of is that Amanda has not read
correctly our tape drive so I am re-running
#amtapetype -f /dev/rmt/0n
By tomorrow I'll see what the results are and hopefully it should work...
Any thoughts why amlabel is not working are mostly welcome.

Getting Amanda to production
hello, I have a few question in mind so I'll be able to better configure it. 1) So far I tested Amanda and backed up data on a hard drive and am quit happy with the results. Recently we got a new tape drive and I need to start backing up our data into taps. I am going to use the same Amanda server and clients. Should and if so how do I initialize Amanda so it won't care about previous backups? Additionally I'll probably have to do some more testing in order to see how much time/bandwidth Amanda uses when it backup to our tape drive. But after doing those tests - can I delete those files from the tape? 2) I understand that Amanda has its algorithm that decides when do to a full backup, or an incremental one. But I am a little confused with labeling tapes. (amlabel) When I used the hard-disk I define each hard-drive 'partition' as 4GB and then amlabel each disk e.g. #/usr/sbin/amlabel DailySet1 HISS01 slot 1 #/usr/sbin/amlabel DailySet1 HISS02 slot 2 ... However, I have tapes that each can store 400 compress data, and we have to store about 30GB - am I domed to use each tape for one backup - or can I 'partition' those tapes? Do I have to put each tape in the tape drive and run amlabel? 3) We have a local and remote sites that we have to backup any thoughts, comments on what should I keep in mine before doing so. Additionally any recommendation for what to use to secure our data when backing up remotely? I read that I can use TCP wrappers but how do I implement it with Amanda? 4) Finally, we have one tape drive and about 20 servers that we need to backup from. Some of those servers run on Solaris, some on Windows. Can I back all servers on the same tape, or do I need to set separate tapes for Win machines? Many thanks, gil
RE: Getting Amanda to production

Currently you probably do a cronjob with amdump vtapeconfig, simply comment that out entry and add an amdump realtapeconfig.

However, I have tapes that each can store 400 compress data, and we have to store about 30GB - am I domed to use each tape for one backup yes - or can I 'partition' those tapes? no What some who have a large holding disk(s) space is to let several dump runs collect on the holding disk(s) by not putting a tape in the drive. Amrecover, I'm pretty sure, works with the taped or holding disk dumps. Then insert a tape and amflush them to tape. Do I have to put each tape in the tape drive and run amlabel? yes 3) We have a local and remote sites that we have to backup any thoughts, comments on what should I keep in mine before doing so. Additionally any recommendation for what to use to secure our data when backing up remotely? I read that I can use TCP wrappers but how do I implement it with Amanda? Don't bring them all on line at the same time. Make all your disklist entries but put a # sign to comment them out. Uncomment a couple each dump. Run amcheck with several from each client uncommented BEFORE even thinking about a dump. Maybe use your vtape config to test drive a client before moving them to the big show. 4) Finally, we have one tape drive and about 20 servers that we need to backup from. Some of those servers run on Solaris, some on Windows. Can I back all servers on the same tape, or do I need to set separate tapes for Win machines? Both can share a config. Lots of ways to do the M$ machines, none fully satisfactory. Samba clients to one or several of your unix hosts, nfs shares if your M$ boxes are nfs servers (possibly from M$'s free Services For Unix product - SFU), some windows backup program that writes to a file and backup that single file/directory with amanda, install cygwin on each box and install amanda so it looks like a unix host. Many limitations to backing up M$ boxes, set your expectations low and you won't be unhappy. -- Jon H.

mounting/identifying a new tape drive
Hello, I have a Solaris 9 box and we bought a new tape drive model Certance LTO-2. Currently, I am trying to identify the tape drive using amtapetype command but it does not work. Let me go a step back and describe what I did so far. I connected the new tape drive to our Solaris 9 server and I restarted Solaris. Next in order to see that the server identified the new hardware I typed: #iostat -En and received the following output regarding the tape drive: # rmt/0 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 # Vendor: CERTANCE Product: ULTRIUM 2Revision: 1703 Serial No: 5150-400 Finally, I want to run the amtapetype to identify the tape type definition but was enable to do so! When I typed: #amtapetype: /dev/rmt I received the following error message: #amtapetype: /dev/rmt: rewinding tape: Inappropriate ioctl for device When I typed: # amtapetype: /dev/rmt/0 OR #amtapetype -f /dev/rst13 OR #amtapetype -f /dev/nrst13 The output is : # amtapetype: could not open /dev/nst13: No such file or directory Any idea why I am getting those error messages and whether I miss a step in defining a new tape drive, or any command that describe where the new tape drive is mounted? This is propably a silly question but I am stuck so any help is welcome... Thanks for your help, gil

Backup priorities and initialization of backup
Hello, I am quit new with Amanda and I dont understand an important concept regarding Amanda. I realize that Amanda decides what type of backup to perform (level 0 , level 1 etc) according to its algorithm. However, how does it knows which backup level to perform when a user have a tape drive with X different tapes that are manually changed? Is there a file that tells Amanda which backups has been performed and if so what is this file name? Finally, so far I have been changing the file disklist in order to check different backup scenarios. The file tapelist was automatically updated: The new tapelist file looks like: 20041222 DailySet105 reuse 20041222 DailySet104 reuse etc At this point, I want to run the backup which means I have to initialize all my experiments so far any ideas on how to do so? Which files do I have to modify in addition to the disklist file. Thanks, Gil

To test this with smbclient, do: smbclient '//homeros/d$' -U 'amanda%secret' -W MYDOMAIN And you should get the smb: -prompt, and type e.g. dir to list the files. If you add on each PC a local user instead of the domain user, then you should not add the MYDOMAIN value to /etc/amandapass, and test without the -W MYDOMAIN option for smbclient, of course. -- Paul Bijnens, XplanationTel +32 16 397.511 Technologielaan 21 bus 2, B-3001 Leuven, BELGIUMFax +32 16 397.512 http://www.xplanation.com/ email: [EMAIL PROTECTED] *** * I think I've got the hang of it now: exit, ^D, ^C, ^\, ^Z, ^Q, F6, * * quit, ZZ, :q, :q!, M-Z, ^X^C, logoff, logout, close, bye, /bye, * * stop, end, F3, ~., ^]c, +++ ATH, disconnect, halt, abort, hangup, * * PF4, F20, ^X^X, :D::D, KJOB, F14-f-e, F8-e, kill -1 $$, shutdown, * * kill -9 1, Alt-F4, Ctrl-Alt-Del, AltGr-NumLock, Stop-A, ...* * ...

using Amanda remotely
hello, We have servers(Solaris 9) on two different locations and when I am running amcheck I get the following error message: WARNING: host2name.com: self check request timed out. Host down? Client check: 1 host checked in 30.029 seconds, 1 problem found I can ssh remotely the server. I already set the .amandahosts with the appropriate hosts on both the Amanda server(localy) and on the remote Amanda client to allow access to this host. Do I miss something with the configuration? - I had no problem backing up different servers on the same site. Thanks, gil

Thanks, gil In addition to what Brian suggested, verify that any firewalls (or router ACLs) between the servers allow Amanda traffic. If you haven't compiled Amanda with the portrange options, it needs to be faily wide open in both directions.

Recommendation for tape drives
hi, Can someone recommend a tape-drive that works well with Amanda and can backup about 40-60GB. Thx, Gil
RE: Recommendation for tape drives
Some more specifications regarding getting a tape drive: I have a Solaris 9 box which will be the Amanda server I have to back up another Solaris box as well as a few Window2000 boxes. The budget for the tape drive is about 500$ to 1000$ (without Jukebox - too expensive) I would like to use compression, yet I have no idea about the compressibility of the data. My preferences would be: 1) A device that can store 30GB or more. (most important) 2) Easy to configure with Amanda.(very impportant) 3) Reliable (very impportant) 3) Fast to record and recover (less important) thx :) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Brian Cuttler Sent: Friday, December 03, 2004 1:27 PM To: Gil Naveh Cc: [EMAIL PROTECTED] Subject: Re: Recommendation for tape drives Gil, Amanda uses native utilities to write the tape drive. If you tell us your OS we might have specific recommendations. Do you have any idea the compressability of your data, and if you want to use compression or not ? Jukebox ? Budget ?
