There is delay between a) when rsync collecting what needs to transfer and b) the actual transfer. Files changed between a) and b), that is what is happening.
Tomas, That's what I thought.
You could avoid it by 1) not writing/deleting stuff on the disk when your backup is in progress or 2) by making filesystem snapshot and backing up the snapshot. 1) is probably not practical. 2) would require filesystem change to COW filesystem such as btrfs on Linux or zfs on BSD. Common practice is to live with the errors or 2).
Dirvish runs at 00:30 and I'm not working on the host then. I've encountered errors backup up /home if I run dirvish while I'm logged in; otherwise the error is a very rare occurrence. I think it was an incoming message then but I've not looked at the mail log. Thanks, Rich
