Hi!
Sorry, if I'm asking something obvious, but I recently got to manage an
amanda server and do not have that much experience with amanda. And we
encountered some problems recently.
We used a very old workstation to do some backups on tape until the tape
drive died. So we put in a raid of 2 200GB IDE hard disks to be our
holding disks and just don't flush to tape anymore.
My problem is now, that amanda still shows the tapes in amoverview. May
I delete all tapes from the configuration and amanda will still work? Or
do I have to leave at least one tape in the configuration.
You may "amrmtape" all of them. Beware that you also erase the online
information from those tapes: if you ever want to restore from them, you
cannot use "amrecover" (but you can use "amrestore").
But I guess, you will not replace the tapedrive anymore, so will not
even be able to read the tapes.
I know, that there are better ways to get amanda save to hard disk, but
we needed a quick workaround and I'll switch to hard disk backup as soon
as I have some spare time.
Quick setup with vtapes (takes only 15 minutes, if you can type fast
enough):
Create the virtual tapes:
# mkdir /space/vtapes
# chown amanda:disk /space/vtapes
# su - amanda
$ mkdir -p /space/vtapes/daily/slots
$ cd /space/vtapes/daily/slots
$ for i in 1 2 3 4 5 6 7 8 9 10 11 12 13 14; do mkdir slot$1; done
$ ln -s slot1 data
In the above: create as many slots as you have specified "tapecycle"
in the amanda.conf.
And finally lets see if it works:
$ ammt -f file:/space/vtapes/daily/slots status
in amanda.conf:
tpchanger "chg-disk"
tapedev "file:/space/vtapes/daily/slots"
changerfile "/home/amanda/daily/changerfile" # contains statusinfo
changerdev "changer"
Then label the tapes:
$ amlabel daily DAILY-01 slot 1
$ amlabel daily DAILY-02 slot 2
...
$ amlabel daily DAILY-14 slot 14
And reset to first slot again:
$ amtape daily reset
And you're ready for the first amdump/amflush.
