tar escaping into a different file system
Finally I'm getting back on track after the tar 1.15.91-2 incremental changes. Due to this issue and my yearly holidays, my backups are long overdue and Amanda likes to do lots of level 0s (as expected). I just noticed this in the mail log of last night's backup: | /-- anakin / lev 0 FAILED [data write: Connection reset by peer] | sendbackup: start [anakin:/ level 0] | sendbackup: info BACKUP=/bin/tar | sendbackup: info RECOVER_CMD=/bin/gzip -dc |/bin/tar -f... - | sendbackup: info COMPRESS_SUFFIX=.gz | sendbackup: info end | ? gtar: ./proc/19106/fd/5: Warning: Cannot stat: No such file or directory | ? gtar: ./proc/19106/task/19106/fd/5: Warning: Cannot stat: No such file or | directory | ? gtar: ./proc/6490/task/19182: Warning: Cannot stat: No such file or | directory | ? gtar: ./proc/6490/task/19182/attr: Warning: Cannot stat: No such file or | directory | ? gtar: ./proc/6490/task/19182/attr: Warning: Cannot stat: No such file or | directory | ? gtar: ./proc/6490/task/19182/fd: Warning: Cannot stat: No such file or | directory | ? gtar: ./proc/6490/task/19182/fd: Warning: Cannot stat: No such file or | directory | ? gtar: ./proc/asound/card0/pcm0p/sub1: file changed as we read it | ? gtar: ./proc/irq/14/ide0: file changed as we read it | ? gtar: ./proc/sys/fs/mqueue: file changed as we read it | ? gtar: ./proc/sys/net/ipv6/conf/default: file changed as we read it | | gtar: ./dev/gpmctl: socket ignored | | gtar: ./dev/log: socket ignored | \ Since /proc is on a separate file system, tar is not supposed to enter that directory. Anyone seen that before? I'm using tar 1.15.91-2 and amanda 1:2.5.0p2-1 (+ my backport of the fixes for tar 1.15.91, cfr. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=378558), on Debian testing/unstable. Is this another tar 1.15.91 breakage?

Correct use of amflush
Hi, I'd appreciate some advice on what is regarded as the correct usage of amflush and the tapes to use with amflush. If the need to run amflush occurs, then amanda tells you which tape to use next, or that you can use a new tape. My question is simply this: Is it acceptable to use the next (already labelled) tape for the amflush operation, or is there any reason why amflush should rather/only be done with a new tape? E.g. I use daily-1 for a backup run, and the backup fails for some reason and some data is on the holding disk. Amanda tells me that she expects daily-2 or a new tape for the next run. I run amflush, and amanda wants a tape. Is it alright to use daily-2, or is it better to use a new tape? Thanks very much. -- View this message in context: http://www.nabble.com/Correct-use-of-amflush-tf2026836.html#a5573711 Sent from the Amanda - Users forum at Nabble.com.

If you're going to use an existing tape, daily-2 is what amanda will want. At any time it's always acceptable to use a new tape. If you use a new tape amanda will add it to the normal rotation at this point. What you choose to do is up to local policy. -Mitch
Re: Correct use of amflush
Aha - thanks for that! That was kind of what I was wondering about - didn't realise that amanda will add it to the rotation, so I thought what happens to the tape then... I wonder - how will amanda handle labelling the new tape, then? Will you be asked to label it first, manually, or does amanda label it automatically? Thanks!

Still struggling with L0
Guys I'm have _real_ trouble trying to force Amanda to do a L0 backup of the system that was effected by Amanda wiping out the last L0. I've tried to force a L0 backup of it, like : amadmin DailySet1 force qtvpdc.lab:/Shares amadmin: qtvpdc.lab:/Shares is set to a forced level 0 at next run. But when amdump runs, it just schedules a L1 or L2 backup. As you can imagine I'm not best pleased as I _still_ haven't been able to get an L0 of this system on tape 5 days later (after severely reducing the filesystem size) Any ideas ??? Cheers -- AlanP
Re: Still struggling with L0
The little bit of experience I have of amanda has showed me that "dumpcycle 0" in amanda.conf will force a level 0 (full) dump. I've been running amanda in a test lab with that setting before going production with incremental backups. Probably not the correct way of doing it in your case, but maybe it works if all else fails?

amcheck error
Amanda version: 2.5.0 Linux: Fedora Core 4 Windows Amanda client: Downloaded from http://prdownloads.sourceforge.net/amanda-win32/amanda-clients-2.5.0-2001062 8.zip?use_mirror=nchc and installed it on the Windows platform. The amandad service is successfully starting by running the rc.amandad batch script on the Windows side. On the Amanda server (running Linux OS), we did the appropriate configuration of the amanda build by running the following configuration line: ./configure --with-user=amanda --with-group=backup And successfully did the make and 'make install' as well (after creating the user 'amanda' and group 'backup') We went and created the appropriate entries in the amandahosts file in the following format and placed it in the home directory of Amanda user: The amcheck utility is throwing out an error stating that "access as amanda not allowed from [EMAIL PROTECTED]". Is there an issue running the client on Windows and the server on the Linux server? The basic communication between the amandad client and the amcheck run on the server seems to be fine since the name of the server gets succesfully printed on the amandad client window when a request for a connection goes successfully to the client. Is there a requirement that we need to run Cygwin mandatorily on the Windows client for getting this up and running?

Recovering files from DVD-recorded backup
After the struggle to burn my tape-split backups onto DVD, I find myself wondering just how useful they are. The current set of backups are still on hard drive, but what if I want to find an earlier copy of a file which has since been burned onto DVD? It seems to me that once vtapes are free for overwriting the corresponding index will be lost too. Can either amrestore or amrecover actually access these files?

You do realize that you are, or will soon be, the leading expert on saving amanda backups on optical media, right? Suppose you had a different config for recovery (rec-config). The rec-config might use nearly all the same config data and could use the same curinfo/log/index directories as your normal config. Further, suppose you never deleted (amrmtape) or overwrote a vtape in your regular config (unless the dvd data were no longer needed). That would keep the index and log files available for amrecover. Your rec-config could use a device, maybe with chg-manual, that had "data" pointing to your dvd mount point (a symlink). I'm not thinking well enough to recommend how to handle the current vtapes. Maybe rm the data a day or two before reuse, relabel the vtape with amlabel for a new label, and maybe rename the slot one greater than current max. Another totally off-the-wall brainstorm; what if you reserve one slot in your changer directory as a symbolic link to your dvd mount point. Say it was slot99 or slot1 or ???. Perhaps when amrecover asked for a particular tape you could mount the appropriate dvd, and ammt/amtape it to the current active changer position. I was thinking about that from my current installation. My actual storage is on two external drives. My changer "slot" directory is on the hard system's hard drive and the "slotXX" directories are actually symbolic links to external drive directories. It could just as well point to a mounted dvd directory. Such an approach would be testable with your current setup. Rename the slotXX containing the original hard disk data. Recreate slotXX as a symbolic link to your dvd data. Try amrecover. You would still need to retain index etc. and relabel hd tapes. -- Jon H.

Can either amrestore or amrecover actually access > these files? Barring defects in the file/media, amrestore can *always* be used to recover an amanda backup. The procedure isn't quite as automated as amrecover. Here's an outline of what you might need to do: 1) Determine what tape you actually need. You might not know this for real the first time! Trial and error may be required. 2) Mount the DVD, say at /mnt. 3) To figure out what backups are on the tape, run something like this: # amrestore -f 0 -p file:/mnt/tapeX invalid-host > /dev/null This says to start at block 0, of the tape file:/mnt/tapeX (path depends on how you named tapes/burned them), search for "invalid-host" and throw the data to /dev/null. This command will give you a printout of the contents of the tape like this: amrestore: 0: skipping start of tape: date 20050128 label DailySet117 amrestore: 1: skipping blah.sda1.20050128.2 ... This output is formatted like "hostname.device.date.dumplevel". Find the dump that you are looking for. Let's assume we want to restore from "blah.sda1.20050128.2". 4) Now we run a valid amrestore command to get data: # amrestore -f 1 -p file:/mnt/tapeX blah sda1 | restore -if - This pulls data for blah:/sda1 from file:/mnt/tapeX starting at block 1. You'll get a shell very much like amrecover that you can navigate the filesystem dump, add files, and extract them. If you use tar, you'll want to do something like: # amrestore -f 1 -p file:/mnt/tapeX blah sda1 | tar xpvf - to untar the tarball into your current directory. -- Ross Vandegrift [EMAIL PROTECTED] "The good Christian should beware of mathematicians, and all those who make empty prophecies.

I'm surprised at the resulting message. When I tried a similar bad syntax I got "amadmin: no disk matched" The amadmin info command shows when a DLE is set to forced. Here is one I forced for demo.

Thats one of the beautifull things about amanda, basic system tools can do a restore without amanda's help. >Anne -- Cheers, Gene People having trouble with vz bouncing email to me should add the word 'online' between the 'verizon', and the dot which bypasses vz's stupid bounce rules.

Re: Still struggling with L0
Ooops Sorry that's what I typed, cut and paste was a bit off as I tried to remove the company name from the host ! Finally got a L0 pumped to tape, after several runs (other errors were involved such as exclude list wrong) many thanks everyone. -- AlanP On Mon, July 31, 2006 8:24 pm, Mitch Collinsworth wrote: > > On Mon, 31 Jul 2006, Alan Pearson wrote: > >> I've tried to force a L0 backup of it, like : >> >> amadmin DailySet1 force qtvpdc.lab:/Shares >> amadmin: qtvpdc.lab:/Shares is set to a forced level 0 at next run. >> >> >> But when amdump runs, it just schedules a L1 or L2 backup. > > Syntax: > > % amadmin help > > Usage: amadmin {} ... > Valid s are: > version # Show version info. > force [ []* ]+ # Force level 0 at next run. > unforce [ []* ]+ # Clear force command. > force-bump [ []* ]+# Force bump at next run. > force-no-bump [ []* ]+ # Force no-bump at next > run. > unforce-bump [ []* ]+ # Clear bump command. > reuse ... # re-use this tape. > no-reuse ...# never re-use this tape. > find [ []* ]* # Show which tapes these dumps > are on. > delete [ []* ]*# Delete from database. > info [ []* ]* # Show current info records. > due [ []* ]* # Show due date. > balance # Show nightly dump size balance. > tape# Show which tape is due next. > bumpsize# Show current bump thresholds. > export [ []* ]*# Export curinfo database > to stdout. > import # Import curinfo database from > stdin. > disklist [ []* ]* # Show disklist entries. > > > So your "amadmin DailySet1 force qtvpdc.lab:/Shares" > should be "amadmin DailySet1 force qtvpdc.lab /Shares" > > -Mitch >

But are you sure Amanda is fully operational on the Linux machine first? - what "amcheck -s " is saying? - what is you have a DLE for the Linux machine only and try "amcheck -c " ? - what is you let Amanda run with the Linux machine only? Once I am sure the Linux server is working, I would see to the Windows client. Bests, Olivier
