When I had only one tape drive, I ran a script which contained amdump $config amtape $config eject (I don't remember who suggested it to me, but thanks!) Now I have two drives configured as chg-multi, but sometimes backups only require one tape. amtape doesn't know how many tapes were used. I modified the script. amdump $config amtape $config slot 1 amtape $config eject amtape $config slot 2 amtape $config eject Each day I still need to figure out if a tape wasn't used and needs to be reloaded. I resisted writing a perl script to handle ejecting because I was concerned about keeping the list of tape drives up-to-date in both amanda and the perl script. Yes, the drives don't change often, so that was probably a silly concern. perl could probably figure out which tape shouldn't be ejected from a combination of "amadmin tape" and "amtape show". Then, maybe, I could turn the daily tape handling over to someone else, who only had to insert the next available tape(s) in the available drive(s). Ron [EMAIL PROTECTED]

Well, there's not much to it, in amanda's crontab entry, just do something like: 55 23 * * 0 amdump DailySet1 amtape DailySet1 eject or 55 23 * * 0 amdump DailySet1;amtape DailySet1 eject Or should I write a perl or shell script to automate the both the dump and eject tape process? This is also a perfectly viable option. Personally, I like simplicity, so I'd probably opt for one of the above methods. But, as Dave W. pointed out, if you use an autochanger, you can just run amcheck right after the dump is done, and this will accomplish the same thing. The way I handle it with my autochanger is to set up crontab entries for each day of the week to run 'amtape config slot #' to make sure the correct slot is loaded each day. A little verbose, and probably better handled with a script, but it works: 45 23 * * 1 amtape DailySet1 slot 1 This runs 10 minutes before amdump runs. I have one for each day of the week. I did it this way so that it was obvious to anyone else what was going on. I may place it all in one script and exec that instead, but either way works just fine. -- Seeya, Paul I'm in shape, my shape just happens to be pear! If you're not having fun, you're not doing it right!
Re: ejecting amanda tape - after dump finishes
Now I have two drives configured as chg-multi, but
sometimes backups only require one tape. amtape doesn't
know how many tapes were used. ...
I also use a script around amdump (et al) and just run that from cron.
It's available at:
ftp://gandalf.cc.purdue.edu/pub/amanda/run-amanda
if anyone wants it for a starting point. The above is for 2.4.2.
There is also run-amanda-2.4.1 there for that release.
Among other things, it runs amtoc. Prior to 2.4.2, it needed to know
how many tapes were used during this run, ala the need for you to know
how many tapes to eject. The technique I used was to copy the tapelist
file before the run (actually, I copy all the config files before the
run "just in case") and diff it with the one after. The following is
ksh code, adjust as needed for your shell, and tapelist.0 is the file
at the start of the run:
diff tapelist.0 tapelist \
| grep '^ ' \
| while read flag date label junk
do
print "$(ts) Creating TOC for $label"
${DEBUG} $base/sbin/amtoc ${config} -f -l $label
done
If you just want to know how many tapes were used, this should do it:
numtapes=$(diff tapelist.0 tapelist | grep '^ ' | wc -l)
