Hi,
I have a disk that is a cache for database backups
and is a set of 30 directories with database exports
of the last 30 days. I want to use Amanda to backup
ONLY the latest written directory every night,
without ever doing a full backup of the whole disk
(it is too big
to fit on one tape! :(  )

In other words, is there a way to tell Amanda to
always back-up only the changes from the last run
regardless of dump levels. Equivalently, is there a way
to fool Amanda into thinking that a full backup was
done every night, after the level 1 completes
successfully.

Any other ideas would be appreciated!

Cheers,
Milos
