flexbackup and single files restore?
« on: April 20, 2001, 03:11:44 PM »
hi,
i just deleted a file that should not be deleted on my e-smith server (in an ibay)! so i started my ssh client to restore the file with flexbackup (running on my IDE Seagate Hornet tapedrive).
that's the log of the backup:

WHAT IS WRONG WITH MY BACKUP?
is the device /dev/nst0 the IDE tapedrive?
where is my daily backup saved to? (cron daemon?)
i want to change it to only backup on some days a week - how?

thx for your help!

OK it worked (i changed some cron files and the flexbackup.conf [dev/nst0 to dev/nht0]) - now my backup fails?!

It is not clear what you are doing.  You had mentioned your backups were working and you simply wanted to restore a file.  If this is the case then there should have been no need to change anything, so a cron and flexbackup.conf change was definitely not required nor is this the way to change these files anyhow as they are templated and device changes are done via db entries.

Put everything back the way it was, (when it was working) and then simply run the interactive restore command as noted in my:
