Error while recovering files
Hi Sir, Sometimes I get this errors while trying to recover from my tape. EOF, check amidxtaped.debug file on chino.master.com. amrecover: short block 0 bytes UNKNOWN file amrecover: Can't read file header extract_list - child returned non-zero status: 1 Is this because I must format all tapes before I use them(they are all used by NTBackup previously)? warmest regards, Desmond Lim System Administrator http://www.kikuze.com/ AP Co-ordinator Pte Ltd 6 Aljunied Ave 3 #01-02 Singapore 389932 Tel: 7460188#322 Fax: 7462550 HP: 94525736
index generation
Hello People! I have another problem, this time about indexing. When I start "amdump Daily" the backup-procedure works well but thereis index-file being created within the index-directory which is set to "/usr/adm/amanda/index". So what did I wrong? Greetings, Volker
re-index old tapes ?
Hi, When installing amanda, I set up a tape cycle of about 20 DAT2 tapes named TAPE01 to TAPE20. some months ago, I upgraded the streamer to DAT3, put the old DAT2 tapes away and labelled 20 new DAT3 tapes with the names TAPE01 to TAPE20. from the point of amanda's view, it was a seamless migration to the new dat drive/tapes. the problem is: I urgently need to restore files from the old DAT2 tapes which are, of course, no longer in the current amanda index. Is there a possibility to re-index such tapes, even if they have the same label as a current one ? is it wise to re-label the old tape to a different name or will re-labelling erase them ? tnx in advance.

RE: amanda - DATA timeout?

Samba problem.
Hi guys!
i've got 2.4.2p2 running great on multiple linux boxes . . no problem.
just got a NAS in and need to set it up for backup.
1. i created a user on the NAS and granted it rights as needed to
backup.
2. created a share specifically for backup and set correct rights (read
only . i don't mind making a full dump of this NAS every night . .it
needs it)
3. smbclient was found when i installed 2.4.2p2 . . but i did a make
clean and reconfigured with the --with-smbclient option when i started
having problems.
4. i have an entry in disklist as such:
nas-1 //nas-1/back samba-comp-tar
5. here's the amanda.conf dumptype entry:
define dumptype samba-comp-tar {
program GNUTAR
options no-compress
priority medium
}
6. the amandapass is setup correctly:
//nas-1/backamanda%password
7. on running amcheck normal (my backup routine)
i get this error:
Amanda Backup Client Hosts Check
WARNING: nas-1: selfcheck request timed out. Host down?
Client check: 4 hosts checked in 30.130 seconds, 1 problem found
any ideas? i have run smbclient by hand, no problem . .got into the NAS
easily with the amanda user and pass. i double checked the Makefile to
ensure that smbclient was set correctly before make . .. .

tar
Hi After being bitten by a problematic GNUTAR I'd like to make the following suggestion: In the amanda source distribution include a properly patched version of GNUTAR, that people can build and use regardless of the tar that came with the system and be sure that they are using a good and safe tar instead of trial and error on any tar they have with the system (applicable to Linux systems) or what GNUTAR version they find on the internet (which isn't always the right one anyhow). Comments? Paolo

Chewed Backups
Hi
After completing the first dump cycle, I thought it was time to test Amanda,
to make sure that I could restore in case of emergency. It's a good thing
that I did. amrecover comes out with 'UNKNOWN file' whenever I try to
restore anything. I read the docs and tried to read the headers, and got this:
# mt rewind
# mt fsf NN
# dd if=/dev/rmt/0bn bs=32k count=1
AMANDA: TAPESTART DATE 20010615 TAPE xx0
1+0 records in
1+0 records out
Looks like the tape is hosed, tried a random selection and it looks like
I've never completed a run successfully here, although never had an error...
Any ideas? This is a Tandberg DLT 7000 running Amanda 2.4.2p2 on Solaris 2.6...
the only clue I have is something about Variable Length I/O in syslog, if
anyone has a working st.conf for this drive in Sol2.6 then I can eliminate
that possibility.
FYI, Tape type definition I'm using:
define tapetype DLT7000-IV {
comment DLT7000 with DLTtape IV uncompressed
length 35000 mbytes
filemark 8 kbytes
speed 5000 kbytes
}
Thanks

Re: re-index old tapes ?
the problem is: I urgently need to restore files from the old DAT2 tapes which are, of course, no longer in the current amanda index. Is there a possibility to re-index such tapes, even if they have the same label as a current one ? ... Amanda does not have a mechanism (although it should) to regenerate index files. And, as you have surmised, things might get a bit confusing with the same range of labels. Also, the log.MMDD.NN files (which Amanda has probably cleared out), are also needed for amrecover. Here's what I would do. First, I'd get a catalogue of what is on each tape like this and save it away: amrestore -p $TAPE no-such-host Then, for the images I needed (particular clients and disks), I'd regenerate the index information. How that's done depends on what type of program generated the image and what OS is on the client. If it's GNU tar, or if the client and tape server run the same OS and the tape server has the restore program available, you can do it there, something like this: mt rewind mt fsf NN amrestore -p the-client the-disk | gtar tbf 2 - index.client.disk.level (you will also need a gunzip in the pipeline if you used software compression). If you don't have the right software on the tape server, stick an ssh/rsh in the pipeline and send the image back over to the client to do the indexing there. Now you can find which image has the files you need, find the tape with that image, and do the restores by hand with amrestore piped into the restore program. is it wise to re-label the old tape to a different name or will re-labelling erase them ? You cannot relabel a tape. Everything after the last write is lost, and since the label is at the beginning, it would clobber all the data. John R.

Dumping to hd
Hi all, I would want to know if specifying holdingdisk yesin my dumptype will put my backup only on the holding disk without writting it on tape (which is exactly what i want). I'm asking this because i have 3 backup sets but only one tapedrive. One of the sets being daily and the other two being full backups every week (working on weekend). Since i'm not at work on weekends i cannot change the tapes, so what i though about was to do the dumps on the disk and then run amflush on monday, this way the daily dump of monday at 1 aM can be done... Tell me if i am wrong with that, i wanted to be sure. Thanks

The HP DAT40 I have doesn't integrate an internal terminator on its controller board. So you will need to terminate the chain with a SE Wide terminator, or a LVD Multimode Wide terminator. Thanks - I thought as much. Actually, we've been sent an Adaptec 2940U, which is not a wide SCSI card. The supplier tells me that this will do for just the 1 DAT drive. The trouble is that they haven't supplied the 68-to-50 pin adapter either. This isn't helping my schedule! Tom

If you label your weekend types different from the daily sets, the dumps will sit on the holding disk until the right tape will be in your drive and you flush them out using amflush.

Backup schedules
I'm attempting to expand my company's backup system to encompass more servers, and I'm a little confused as to how AMANDA handles multiple servers in rotation. For instance, I'd like to backup servers A B on the same tape every thursday, server C every tuesday, and server D on Mondays, wednesdays and fridays. Can AMANDA handle this from one config, or does it require 3 separate configs and crafty cron manipulation? -- Matt Barringer WireX Communications, Inc.

Re: Problems with amcheck and tape labels
John, Apparently I confused every one with my explanations. Of course I run amcheck BEFORE amdump, but that also means that amcheck is run after the previous amdump And the output of the amcheck on tape DailySet109 was just to prove that the tape does have a valid label! The problem occurs when I do put the valid tape in for the next run and amcheck is run, it then compains that the inserted tape isn't an amanda tape and if I check the first block using dd it does seem like if the tape was blank ... Does this make things clearer Pat. John R. Jackson wrote: I have this constant recurrant error, that every day the amcheck is failing just after a succesfull amdump. I don't understand. Do you really mean you're running amcheck **after** you run amdump? Why? Usually it's run **before** amdump so any problems it finds can be fixed before the run. for instance the day before tape DailySet109 is dued I run amcheck and get the following: Amanda Tape Server Host Check - Holding disk /amanda2/amanda/work: 985386 KB disk space available, that's plenty ERROR: cannot overwrite active tape DailySet109 (expecting tape DailySet108 or a new tape) This says that even though *you* thought DailySet109 was the next tape to be used, Amanda thinks the next tape should be DailySet108 and that DailySet109 is still active. It sounds to me like your tape sequence is confused, or you are not getting the right (from Amanda's point of view :-) tape mounted at the right time. How are you deciding what tape to mount? What happens if you run amadmin config tape? Does it show the tape you expect to be used next (I guarantee it is showing the tape Amanda expects to see next)? If you mount that tape, is amcheck happy? Pat. John R. Jackson, Technical Software Specialist, [EMAIL PROTECTED]
