How can Dump Time be *GREATER THAN* Run Time?
STATISTICS:
Total Full Daily

Estimate Time (hrs:min) 0:17
Run Time (hrs:min) 9:40
Dump Time (hrs:min) 12:12 12:10 0:02
Clearly, this backup did *NOT* take anywhere near twelve (12) hours.
So, what is that Dump Time value?
What do you think?
Time Management by Women, like Amanda: do many things at once.
If you have 12 machines, each dumping 1 hours 1 minutes, then
the total dump time is 12:12, isn't it?
From my weekly archive run:
Total Full Daily

The dumptime is the time needed when Amanda would run all dumps
sequentially. Amanda does things in parallel.
Run Time is the wall-clock time. The Estimate time is the
first part of this Run Time, when doing the estimates.
(Run Time also includes Tape Time, especially taping
the last image is not done in parallel with anything.)
P.S., Notice the Estimate Time (re: Speed up 400GB backup? thread).
This successful backup is for >65GB, across (17) DLE's, including a
Netware server over ncpfs, and a couple of windoze over samba.
