Just to be on the safe side, and if you are considering to split your
backup anyway, it is better to split into pieces that are smaller than
the tape size.

Not sure if Amanda can split a single DLE onto several tapes. I use a
pre-historic version of Amanda that run single tape :)

Spliting your big DLE into pieces (as many pieces as runpercycle) is
anyway a good tactic, so on every dump Amanda will backup one of the
pieces, and you will end up with equal dump time every day.

Else you will have one big day, doing the 200GB and many small other
days.

Hi Mario,

Take a look at http://wiki.zmanda.com/index.php/Splitting_dumps_across_tapes

Which chapter is that? I could not find it with: lynx -dump
http://www.amanda.org/docs/index.html | grep -i spann

I thought amanda can split such big backup archives up in serveral
parts. I doubt that someone will backup up a 200GB System onto one
single tape.


You're looking for the tape spanning feature, which is explained in the 
docs.  There's also been a lot of discussion recently regarding backups to 
DVDs -- look through the list archives.

So you are saying i should loock for ~4GB directories tar them instead
to dump them?

I thought amanda can split such big backup archives up in serveral
parts. I doubt that someone will backup up a 200GB System onto one
single tape.

A Backup onto DVD would then never be possile???

Thanks, Mario

Make them several DLEs. That means you must use GNU tar, not dump and
you must identify sub-hierarchies, from that too big disk, that will
match your 4.5 GB limit. Time to play with exclude file list.

That said, your tapelist shows 4350 MB, why making chuncks of 4500MB?
