Archiving with amanda revisited
Hi all, Thanks for an excellent software. I was searching the forum and found a question regarding archiving. As I'm using vtapes this would be a great feature to have, being able to collect the 0 images and save them on tape and continue to use the tool kit, amrecover etc. What is the status on this useful feature ? http://archives.zmanda.com/amanda-archives/viewtopic.php?t=3866highligh t=archiving Gunnar Gunnarsson

Currently I am using virtual tapes and after a period of time I would like to send those backups to a LTO Library Tape Unit to take away to a vault our backups.

The stupid way is make an Amanda backup of the vtapes directories. This works, and you data is indeed safe on the tape for offsite storage but restoring from those images is a two way process: first restore the needed vtapes to disk again, together with the index-files, log files (yes!!!), so that you use amrecover on those restored vtapes. Then recover from these vtapes. And while doing this, you have to make sure that you do not overwrite or erase any vtape/index/log from the current situation. Not for the noobs! There is work being done (but don't hold your breath on it) to allow copies of images, together with the needed information like indexes and so on, from one config to another config. That would allow to collect e.g. the level 0 images from a set of vtapes, and put those on tape, while doing the bookkeeping, like indexes, log files etc in the other config (without doing the backup again). While that feature is not yet implemented, currently the best way to do both: - daily to vtapes for fast and easy recovery, - weekly/montlyto tape for offsite storage (only level 0) Implement it in two separate configurations. I run a daily config to vtapes from mon-fri, and an archive config that I run on saterday only to real LTO tapes. That run starts saterday early morning at 00:05 and ends somewhere in the afternoon. It does only level 0 dumps. It has these special parameters: dumpcycle 0 # this forces level 0 always And the global dumptype, from which all the other dumptypes inherit their settings, has specially set: record no # do not interfere with the daily's skip-incr yes # emphasize we only want full dumps strategy noinc # do not even run estimates for incr. level (The last one, makes the estimates finish much faster, as amanda will not generate a plan B degraded mode with incrementals, and does not need to know the size of them.) -- Paul Bijnens, xplanation Technology ServicesTel +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, * * init 0, kill -9 1, Alt-F4, Ctrl-Alt-Del, AltGr-NumLock, Stop-A, ... * * ...

Hi, Steven, on Freitag, 28. Mai 2004 at 16:51 you wrote to amanda-users: SB I have some files I'd like to permanently remove from my system SB (archiving to tape). It would be nice to have them listed in SB amanda's index and have amanda keep track of them for me. Does SB anyone know a way to do this? Simple solution: Do a full backup of those files to a tape in your tapecycle. Mark it as no-reuse with amadmin conf no-reuse TAPE-LABEL You can browse it via amrecover, but AMANDA will not ask for that tape again for a dump. This is a common solution for doing things like monthly-archive-tapes or similar things. Better solution: Setup a config for archiving, with dumpcycle 0, record no, and put your files onto the tapes of this config. -- best regards, Stefan Stefan G. Weichinger mailto:[EMAIL PROTECTED]

It would be nice to have them listed in amanda's index and have amanda keep track of them for me. Does anyone know a way to do this? Mark the tape as no-reuse. Then amanda will not recycle the tape, but still keep track of it. I suggest you add a special config for this, instead of the daily. Call it archive or such. Add record no, dumpcycle 0 and index yes to the dumptype, (and even skip-incr yes and strategy no-inc to speed up estimates). record no is important to avoid messing up the daily schedule. I suggest you use gnutar to backup; who knows what hardware you need to restore the files to in 5 years from now. Add the necessary entries to the disklist. Label a tape, e.g. ARCHIVE-, or even ARCH-20040528-BigProject. Run amdump archive. Run amverify archive. Run amadmin archive no-reuse ARCHIVE-. rm -rf BigProject It's nice to let amreport generate some Postscript labels to go with the tape too. -- 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, ...* * ...

One point in addition to what everyone else has said: it would be wise to make at least two copies of the archive tape(s). Media has a nasty habit of going bad over time. When I had to archive and delete some data, this describes how I made duplicates of the archive tapes: http://groups.yahoo.com/group/amanda-users/message/49373 (Simply amdumping twice would not make *identical* copies, since the first run would change the files' last-access timestamps, if nothing else.) -- | | /\ |-_|/ Eric Siegerman, Toronto, Ont.[EMAIL PROTECTED] | | / It must be said that they would have sounded better if the singer wouldn't throw his fellow band members to the ground and toss the drum kit around during songs. - Patrick Lenneau

Changing the last-access time of a file is only an issue for mechanisms
that open the files in question. For example, tar opens (individual)
files that it reads. On the other hand, {,ufs}dump does not: the thing
it opens is a file system, so it does not change inode contents at all.
That said, there exist other reasons the product of another backup
process is unlikely to be an identical copy of the first.
IIRC, someone posted a note about how he ran an amdump, and as chunks
were written to the holding disk (well, before the chunks were taped
unlinked), he made another link to each file, so after the first taping,
the files in the holding disk were still there, and an amflush run created
another tape with the same data.
Peace,
david
