I tried tar, but it complained about some things, so I'm now looking at
rsync. I want to back up to our Overland LTO3 tape library connected to
the server via a SCSI card. One filesystem is /home, and the other is
/var.
I'd want to create a full backup, with verbose output, and weekly
incrementals.
Again, files may be in-use during backups - no databases in use at this
time. I just have to live with the in-use files situation.
What would be the best rsync method to the local lto3 library (full
magazine with 12 LTO3 400/800 GB tapes).
Thanks again.
Scott
