Backup Central

Hi List !

Were great anyone could help ...

We are experiencing strange errors at the time.
We have an amand-server that backs up about 30 hosts a night.
Most of the time it went well, but now there are very often etrange errors.

It sais:

xxxxx /opt lev 0 FAILED 20040606[could not connect to xxxxx]

And that on about 15 of 30 hosts. The more interesting is, that the
first filesystems (or dle´s) are fine, only some of them are failing.
Next day everything is fine, or other filesystems on other hosts are
failing .. !?
On some days
There seem to be no networking problems, all hosts are 100 Mbit
connected by a 1 Gbit HP Switch separated in VLANS.
The amanda-server is a 1GHz Pentium 3 with 2 2TB RAids attached to it,
so Space should not be the problem.
I wrote a little script, that monitors wih amdump the backup every 3
minutes in a file named date-time, but the output doesnt´t give any
hints ...
Neither the amanda-server, nor the clients tell anything in the
log-files ... !?

Would it be an idea to set (if existent) a higher debug-level at the
amanda-server, and where should i do that ?

Thanks in Advance ...

I would look in the client(s) in the directory /tmp/amanda and there
should be files with a datetimestamp. Have a look in there,
especially in amandad.XXXX.debug. Compare them with a host or
DLE that does succeed.
Post them if they still look normal to you (or mail to me, if privacy
is a concern).

Is that setup working through a firewall?

Did you configure Amanda with one of the 'portrange' options and not allow
enough ports to accomodate the number of hosts you dump in parallel?

Exactly what I thought ;-)
