Errors related to datto in running backups

Hi,

When a backups run, always ends with errors related to datto which I don’t know if save to ignore them:

  • Logs in UrBackup:

Creating snapshot of “/run/cups/printcap” failed
Snapshotting device tmpfs via dattobd…
Using /dev/datto2…
driver returned an error performing specified action. check dmesg for more info: Invalid argument

  • In server:

EXT4-fs (dm-0): recovery complete
EXT4-fs (dm-0): mounted filesystem with ordered data mode. Opts: (null)
EXT4-fs (dm-1): mounted filesystem with ordered data mode. Opts: (null)
datto: illegal to perform setup while unmounted: -22
datto: error during setup ioctl handler: -22
datto: illegal to perform setup while unmounted: -22
datto: error during setup ioctl handler: -22

I don’t know if related to this, but many times files created by datto, does not get deleted. These files are the ones stored in root, with names .datto_* and .overlay_*.

Also I am not sure if this is a problem of UrBackup or Datto.

UrBackup version: 2.1.19.0
Dattobd: 0.10.3

Thanks in advance.

Me too have these messages

i think there is something to configure in datto but i don’t understand what!
