dumps larger than tape

[Rainer Fuegenstein]

Hi,

I'm using amanda now for quite a long time to backup 8 unix hosts on a 4
Gig DAT streamer (uncompressed). Over the course of time, data volume grew
larger and now amanda permanently refuses to backup volume sdb1 on host
sheena:  

sheena sdb1 lev 0 FAILED [dumps too big, but cannot incremental dump
new disk]

I submitted a "amadmin config force sheena sdb1" some days ago, but of no
use. meanwhile, the last full backup of this volume has been overwritten
in the tape rotation.

[rfu@sheena rfu]$ df -k
Filesystem 1024-blocks  Used Available Capacity Mounted on
/dev/sdb14307040 3719800   364340 91%   /web1

sure this volume is quite close to 4 gigs, but compressed with gzip it has
something about 2 gigs which should fit on a tape easily.

is there any chance to get amanda to make a level 0 backup of this volume
until our new 12 gig streamer gets delivered and installed ? would make me
sleep better at night.

thanks in advance.

If the 4 GB volume compresses to 2 GB then you can use software
compression to get your level 0 dump.  Just use one of the dumptypes
that says 'compress client fast' or maybe 'compress server fast', or
add it to the dumptype you're already using.
