I am currently experiencing problems with Amanda backup runs completing successfully, supposedly due to running out of tape. I am using Amanda 2.4.3 on a FreeBSD 4.8-STABLE machine, backing up to 35/70GB DLT 7000 drive. Compression is enabled on the drive, and we are also using compression within Amanda. We are getting nowhere near the expected 70GB compressed capacity of the tapes.
I would guess that something is misconfigured somehow, and I am simply not catching it. If somebody else has suggestions or information on how to deal with these problems, it would be greatly appreciated. Thanks in advance!! --Joshua D.
