Hi there:

I'm doing a backup of some of my machines via rsync, and I have the next problem:

[Tue Feb 22 02:51:13 CET 2011] /usr/bin/rsync -az --delete --numeric-ids --relative --delete-excluded --rsh=/usr/bin/ssh root at server1:/var/spool/exim /data/backups/server1
[Tue Feb 22 02:51:28 CET 2011] /usr/bin/rsync -az --delete --numeric-ids --relative --delete-excluded --rsh=/usr/bin/ssh root at server1:/opt/qpsmtpd /data/backups/server1
[Tue Feb 22 02:51:34 CET 2011] /usr/bin/rsync -az --delete --numeric-ids --relative --delete-excluded --rsh=/usr/bin/ssh root at server1:/opt/spamassassin /data/backups/server1
[Tue Feb 22 02:51:34 CET 2011] /usr/bin/rsync -az --delete --numeric-ids --relative --delete-excluded --rsh=/usr/bin/ssh root at server1:/opt/clamav /data/backups/server1
ssh: connect to host port 22: Connection timed out
rsync: connection unexpectedly closed (0 bytes received so far) [receiver]
rsync error: unexplained error (code 255) at io.c(635) [receiver=3.0.3]
[Tue Feb 22 02:51:55 CET 2011] /usr/bin/rsync -az --delete --numeric-ids --relative --delete-excluded --rsh=/usr/bin/ssh root at server1:/opt/exim /data/backups/server1
[Tue Feb 22 02:51:55 CET 2011] /usr/bin/rsync -az --delete --numeric-ids --relative --delete-excluded --rsh=/usr/bin/ssh root at server1:/etc /data/backups/server1

As you can see the error arise in the same machine, but in a different directory.
This error happens all days with the same directory.
Performing the rsync by hand, it works without any problem:

% /usr/bin/rsync -az --delete --numeric-ids --relative --delete-excluded --rsh=/usr/bin/ssh root at server1:/opt/clamav /data/backups/server1

I'm doing this backup as root via a daily cron.

Any idea about the problem?

Thanks in advance.
