RE: Amanda always flushes holding-disk

Hi, Harald,
--> What Jon said is correct, but I will rephrase from a different
viewpoint

Amanda goes like this:
- grab data from where it lives
- copy to holding disk
- move on to tape:
  - if there is a tape, and there's room on it, and so on
  - move in large chunks, possibly tape sized, so that the tape never
stops

So if there is a problem with the tape, you still do the backup, but it
only gets as far as the holding disk. One advantage of this, if you
have a large holding disk, is that it is moved across the network at the
expected time when network traffic is probably lower. 

Then "amflush" is used to move the data from the holding disk to the
tape when you resolve whatever problem stopped it going to tape in the
first place.

--> Next point: Why did you expect the other behavior?

Are you trying to do disk-to-disk-to-tape backups?
Or just using Amanda to backup to a disk?
These can both be done, but it's slightly more configuration.

I am doing disk-to-disk backup to 250GB disks, then moving the disks (in
USB external cases) to off-site storage. Look ma, no tapes!

For backups to disk, see:

Ok, but what's the "autoflush off" parameter good for?
