the manual. In it, it mentions doing a restore will be about 3 times
slower than a backup.
Now I've got a situation where I have to remove sensitive data that was
backed up on several tapes. The way I'm doing this is to bscan a tape so
as to sync the content to a new catalog, then restore each Jobs in
seperate restore jobs. Once every job has been restored, I search for
the sensitive data, delete and then backup every seperate jobs in one
single job.
So basically I've got a /backup-restore folder that contains each
seperate jobs in their own folder (ie. /backup-restore/01,
/backup-restore/02, ... /backup-restore/9
. I need to do this in order
to prevent files with the same name to overwrite each other. Once I
deleted the sensitive data, I backup the parent (/backup-restore) folder
in a single job.
The problem I'm having with this is that it took 5 days to only do the
restore of each jobs. I had 98 jobs that bscan found and added to the
catalog, all of which are about 100MB to 30GB in size. Here are the
actual stats:

Am I doing this the most efficient way possible? Is it normal that each
job takes progressively longer to complete? I'm getting the feeling the
tape is rewinding and forward spacing a lot for nothing since I'm trying
to restore every job on tape.
Any advice or comments would be appreciated.
