Gee, 15 tapes minimum for one file system.
Are you sure the tape recording speed is sufficiently fast
to allow writing that much data between scheduled amdump's?
ISTR that most tape formats take about 3 hrs to write a full tape.
At that rate it would take 45 hrs for that one FS.

The basic way is to use gnutar as the backup program and NOT back up
the entire FS, but create a series of disklist entries which back up
a sub-tree of the total system.  For example if your big FS mounts as
/big_mama, and has subdirs of /big_mama/proj1, /big_mama/proj2, ...
you could specifiy a separate DLE for each "projx" directory tree.
