Scheduled backups don't work

[Itzel_Gtz26]

I have 2 tasks scheduled to run the backups, one that is local and the other to send to FTP.

These were executed correctly, however, in 3 gateways they stopped executing, in the logs you do not see any errors, it is simply as if they were not programmed, the 4th device sometimes executes the backups and sometimes not.

I thought it could be something with the version and I updated my devices to version R81.10 with the latest hotfix at that time, however this did not solve anything.

Any idea what it could be?

What does /var/log/CPbackup.elg say?

Nothing about the scheduled backups, I only get information about the backups I do at the moment.

Can you attach that file here?
