Is anyone successfully using a mixed strategy of backups to both disk

drive. I have thought about a few different ways to go about it, but
would appreciate suggestions from someone who has tried this approach.
The Snap also has built-in snapshot capability, and I wondered if there
was a way to make use of that in combination with backups to disk.
1. normal amanda backup to holding disk, flush when disk is getting full
2. do full dumps to tape out of cycle and incrementals to disk with
file-driver
3. #2 but also use snapshot technology to keep an even longer history of
incrementals
4. use file-driver, and occasionally archive some of the tape-files to
real tape
Any other ideas?
Set up normal backups to tape, probably already done.
Set up the file:driver to use the Snap server
Set up the RAIT driver to mirror the backups to two devices,
one the file:driver the other the LTO.
Use the LTO for longterm storage, the Snap server for
immediate availability of backups for recovery.
