I have one amanda server and one client. I have 2 separate amanda
configs to backup different DLEs on the client.
The problem is that backups with one config seem to be much slower than
the other. The amanda tar files on the holding disk are being created at
about 10MB/s with one config and 1MB/s for the other config. The tape
writes are fine - it's the creation/transfer of the backup from client
to server that is at issue.
You still have 4.4 MB/s for some server with large DLE in the "slow"
category too. And that's not too bad for a 100 Mbit ethernet interface
either.
A good tool to dig into this problem is amplot:
amplot -e amdump.1
It shows a lot of information. E.g. it could be holdingdisk that
is full, pausing some backup, and making it's average throughput go down.
If you need help interpreting the output, send a xbm or gif or ps to me.
