As far as I can't tell, amrecover won't work unless
1. Log file from the backup you are trying to recover is still present
The log are needed to find which dump are on which tape and where on that tape.
We have the need to keep both weekly full and daily incrementals on disk
(tapeless) so that we won't have
to go to slow media. We then copy full backups (data and inex) to
magnetic tapes for a rotation of 8 tapes
using tar. The disk won't hold up to 8 full backups, so it is set up
with only one "tape". After full backup,
data and index are copied immediately to tape.
This way, we can go back one week, up to any day, using data on disk;
and go back every week
before that, using data on tapes. We do not care much about previous
week's incrementals.
Recover using tapes is done, first with untarring it from tape onto disk
and replacing necessary index
(with data on disk renamed first for preservation, of course), then
running amrecover.
My questions is: Must I have log files tarred to tape along with data
and index in order to run amrecover?
I have never needed to go back more than one week from tape.
Thanks in advance.
