It was our understanding, from reading the Amanda manual and the FAQ,
that if you have a filesystem which is bigger than a single tape (we
do), you will need to do multiple smaller runs, until you have segments
that *will* fit on a tape.
Is that not the case?
We archive data out of a 1.7 TB partition, a set of files sometimes as
small as 300GB, sometimes larger. The tape library has an SDLT220 drive
in it, so our tapes max out at 220GB. We generally need three tapes to
do the archives, using Arkeia right now. Arkeia takes about 7-10 hours
to complete, at about 730-740 MB/mn.
