Hi:

The gzip --best process in the server is to compress the index files, not the 
data.

Dear Listers,

yesterday I configured an amanda server with vtapes and client compression.
Now I see that on both machines (client and server) a gzip process is
running and I wonder why.

The client "hercules" (a samba server, amanda-2.4.4p1-62):

HERCULES:~ # ps aux | grep amanda
amanda    /usr/lib/amanda/sendbackup
amanda    /usr/bin/gzip --best
amanda    /usr/lib/amanda/sendbackup
amanda    sh -c /bin/tar -tf - 2>/dev/null | sed -e 's/^\.//'
root      gtar --create --file - --directory /samba/QS --one-file-system
--listed-incremental /var/lib/amanda/gnutar-lists/hercules_samba_QS_0.new
--sparse --ignore-failed-read --totals .
amanda    /bin/tar -tf -
amanda    sed -e s/^\.//

The amanda server "minerva" (amanda-2.4.5-2):

minerva:~ # ps aux | grep amanda
amanda   /bin/sh /usr/sbin/amdump normal
amanda   /usr/lib/amanda/driver normal
amanda   taper normal
amanda   dumper0 normal
amanda   dumper1 normal
amanda   taper normal
amanda   /usr/bin/gzip --best

The excerpt from minerva's disklist:
hercules /samba/QS comp-high-tar

The excerpt from minerva's amanda.conf:
define dumptype comp-high-tar {
    global
    comment "very important partitions on fast machines"
    program "GNUTAR"
    compress client best
    priority high
}

the dumptype 'global' only contains "index yes".

Any idea?
Thank you and best regards
Uwe
