I had a lot of responses to this and want to thank everyone for their
input. The responses were pretty much the same - here is one of them:
I came across this problem a couple of years and was told by Compaq that
asking for a 2nd volume for a backup that runs from the cron wasn't
possible! Something to do with being unable to handle the standard
output asking for the second volume.
At the time, Compaq mentioned products such as Networker would enable
your backup to go to a second volume.
Depending on the type of tape drive you have, you could elect to get a
bigger capacity tape drive.
Due to our time window being so small, we elected to buy a second tape
drive and we split our backups across the two tape drives.
I am using crontab to schedule my backups:
00 21 * * 1 /usr/local/backup.com
00 21 * * 2 /usr/local/backup_scratch1.com
00 21 * * 3 /usr/local/backup_scratch2.com
00 21 * * 4 /usr/local/backup_scratch3.com
00 21 * * 5 /usr/local/backup_scratch4.com
The backup_scratch*.com file looks like this:
/sbin/vdump -Duf /dev/rmt0m /usr/mountdir/scratch3
exit 0
Most of my backups take two tapes now, it will not ask me for another
tape
- I get this error:
vdump: out of space and unable to prompt input for a new tape: [25] Not
a
typewriter.
Is there some parameter that I am missing?? When I run the backups
manually, I will get the message to mount another tape and when I mount
another one the backup continues. It is just when backups run with
crontab.
