Backup & Migrate scheduled backup silently fail I've tried to use backup &amp; migrate for backups on my omega8 based aegir server.

Although I've defined a schedule, and setup cron interval to 1 hour, it doesn't work - no backups are generated. Scheduled backup silently fail.

Attached is a screenshot of the current schedule:



Notes: 


Module's permissions are default (all marked V for admin).
Backup profile is the default as well.
I'm using Drupal 7. Module's version is 7.x-2.7


Any idea?
It is because you are using buggy module with known issues. This has nothing to do with BOA nor Aegir. There is a reason why we have removed this notoriously buggy module from BOA recently. You should report any such issues in the backup_migrate issue queue on drupal.org - and you may find them reported already, in fact.

This module may still be useful, but only if you follow its issue queue and use release which happens to work. The regressions rate in this module is way too high for us, so we no longer include it by default. Just one example:
