Rsync SSH backups failing
On my readyNAS 102 running 6.6.1, for about a week now I've been seeing rsync backup failures when trying to back up a remote server over SSH. Another server backs up just fine (both jobs were create...
Solved it. There was a typo in a setting in my server sshd_config that was causing client disconnects within 60s on this server. While rsync was calculating the checksum on the NAS (which takes about 10 minutes for this particular file), the ssh connection was being dropped, so as soon as it started to attempt to transfer, the backup would fail. I edited the server config to allow more ClientAliveCountMax retries and it's fine now.
New information - if I delete the original .tar file on my ReadyNAS (in the backup destination) before running the backup job, the backup works fine.
...and now it's working fine again; I've run 3 incremental backups and it works perfectly now after a new initial backup. The odd thing was I did a new initial backup yesterday and the incrementals were still failing afterward, so I'm not sure why it "took" this time. I'll repost if it breaks again.
