Backup to external server with rsync

[jayel]

When I do the backup with rsync I get these errors on the backupmachine :

The error would make me think first of a hardware problem. How are the drives in the system?

What do you mean ?

command : df -h

I'm guessing that he meant you might have a hardware problem with your HDs, have you actually checked them?

Assuming you are not running rsync while the Zimbra backup is running (sorry, but had to ask!) please be sure you are running rsync as root and try turning off rsync's compression (no -z switch), like so:

rsync -avH /opt/zimbra/backup  /foreign_backup_target > /tmp/rsync_output_log.txt

There are a number of reasons why this could be happening, but on the presumption that your hard disks are indeed OK, please try this and let us know

Hope that helps,
Mark
