Comet Backup 1.5.6 — cPanel & WHM Update
Bug fixes This release fixes Comet Backup jobs failing en masse with locked-by-device retention errors on busy servers. The plugin now requests the less-often automatic-retention ruleset for dispatched backups and no longer cancels orphaned in-flight jobs, so overlapping retention passes cannot wedge the device.
