Hi,
I am trying to backup approx 25 Gb of data to a Quantum DLT7000 tape
unit. I have configured an amanda backup server and the client.
Currently amcheck show no problems found and backups do take place. The
oddities begin when I check the report that is sent to me after amanda
has completed it's backup. Amanda's report shows that only 3605 Mb are
backed up. When I check with amrecover, I can see that the files I
backed up are indexed. Can someone please explain why I am getting such
a low number reported back to me by amanda when I am attempting to
backup such a large amount of data? Is there a way to check the actual
size of the backup on the tape? I am using FreeBSD for both my client
and server. I have included some important files below. Thanks in
advance.
