Re: suggestions for RH amanda installation

I'd suggest getting the DBA involved. If the database is running in
ARCHIVEMODE, backing up the redo logfiles should be very doable, even
with such a slow/small tapedrive. Depending, of course, on transaction
volume. RMAN may be useful (though I have no experience (yet) in
implementing it with Amanda...)
Then, full (database) backups can be scheduled based on the maximum
acceptable recovery window.
Also, it's common to design Oracle implementations with multiple
spindles, to spread I/O, even for relatively small databases. You may
find that one drive is dedicated to the SYSTEM tablespace, etc., such
that the amount of changed <user> data is pretty small. Likewise, if
the DBA has any battle scars, he's mirroring his drives potentially
reducing the amount of actual data even further.

Until now I've never seen a 240GB file system :))
Me neither, up to last week, when they called me for advice
how to backup a 800 GB filesystem (4 x 200 GB SATA disks), containing
one large Oracle database. The hardware was completely configured
already, so was the database, so was the tapedrive.
The tapedrive was a DDS3 tape.
Anybody any idea? (No budget for another tapedrive :-) )
Sometimes I really really get tired...
