here's the send sizesize log. To me it appears that it is just taking that long to create the tar..... ???


thanks for your response :).

One of our amanda clients takes an incredibly long time to do estimates
(17000seconds on a level 0, which is about 210GB), and causes the server
to return a estimate timeout error.  Seems to be mainly when it tries to
do a level 0 backup.  the server that takes this amount of time is
accessed through a firewall.

Check the /tmp/amanda/sendsize* logs for any reasons why it is taking too long.

You can try running the tar (I'm assuming that you are using tar not
dump) command
manually.


Is that a typical amount of time, or is something taking WAY too long?
Should I just increase the etimeout in amanda.conf to facilitate the
17000 seconds ?


You could also change "estimate" value to "calcsize" or "server" for
faster estimates (estimates will be less accurate).

See http://wiki.zmanda.com/index.php/Amdump:_results_missing#Timeout_during_estimate.3F

for more information.

Thanks,
Paddy
