I'm trying to backup a home partition with amanda under Sun Solaris 9 with
Amanda version 2.4.4p1:

Filesystem             size   used  avail capacity  Mounted on
/dev/md/dsk/d0         102G    50G    51G    50%    /home

which contains a lot of i-nodes:

Filesystem             iused   ifree  %iused  Mounted on
/dev/md/dsk/d0       2932711 9923481    23%   /home


I can write it to tape in ~5-6 hours using plain gtar but amanda seems to
be busy for several hours (10+) without writing anything to tape. Is there
a workaround to get the partition backed up? Why amanda is so slow? Is it
related to the number of i-nodes or the size of the partition?

Thanks for any help

Zoltan
