I've got a 2.4.2 amanda server using samba to backup the C:\ drive
of an NT workstation. That user's machine has C:\ set as one 8gig
partition, and it's 6gig full. My tapes have just over 4 gig
capacity compressed. (Of course there are many other partitions in this
backup set, but those aren't the problem.)
Amanda pulls the data from the NT disk, and writes it to 5 gigs
worth of compressed disk, in 6 chunks. Now, the compressed sum
of all these sections is already well beyond what the tapetype
says my tape can handle.
So, why is amanda even trying to write 5 gigs worth to a tape it
knows can only hold 4 gig? Isn't it checking?
It keeps running into EOT (like, duh) and it reschedules the same
machine the next day. I've looked at the past week's backups and
all I have is one or two very small incrementals, and repeated failed
attempt to backup this same NT box.
I thought the planner was supposed to be more intelligent than this?
Here's the line for this disk from the amstatus report:
joi://janet/c$ 0 5619328k writing to tape (18:04:52)
Here's the end of the dump log:
| tar: dumped 55234 files and directories
| Total bytes written: 6937226240
sendbackup: size 6774635
sendbackup: end

And here's the tapetype:

filemark 102 kbytes

lbl-templ "/usr/local/etc/amanda/DailySet2/EXB-8500.ps"
}
Here's the schedule:

Why is amanda blowing the tape size by 25%? Why is it being
stubborn about doing this disk, a low-priority user workstation,
instead of doing the medium and high-priority file servers?
