Hello All,
I would like to ask a general Amanda backup 'strategy' question here, given
by backup 'goals' below. I have a configured and working Amanda set-up but I
want to try and fit a backup policy that I believe is best suited to our
site around Amanda.
I have an 8-tape (DLT 35/70gb each

Here's a strategy that I implemented about a month ago that is working
pretty well so far:
1. run amdump every night to large RAID w/o tape, mix of full and incr
2. run script to separate images to amanda-incr and amanda-full
3. when amanda-full exceeds size of tape, run amflush
4. when RAID

I was thinking I could do the incremental backups to a hard disk area on the tape
server each night and then run Amanda once a week to archive the full backups plus
the HDD incremental ones.
I did this once, way back when

I have a tapeless back-up config here with 2.4.3. I have 30 virtual tapes, and so
have amanda.conf values of dumpcycle 30 days and tapecycle 30 tapes
Now, man amanda tells me that this dumpcycle value should mean that each disk using
this set of options will get a full backup at least this
Linebreaks, man, use some line breaks...
Sorry, dude, sorry...
Not that I know of, but in the 2.4.4 ReleaseNotes it says
that it tries to
reduce the number of level 0s per host each night.
I guess that *might* help. I could probably get it down to
a full backup every week. Would I just

However, when I look an amoverview I see that several disks are getting
a full backup EVERY OTHER DAY! What's the idea of this? I'll grant
it's within the letter of the manual, but it's hardly

Yep. Amanda gets estimates for all the DLEs at multiple incremental
levels, and figures out the best thing to do within the
tapelength it has.
Even to the extent of not doing any sort of backup at all on some or many
of the DLEs?

Hmm, dividing my clients into multiple DLEs that I hope will never exceed
