Comet Backup 1.5.6 — cPanel & WHM Update
Affected Versions
1.5.6
What this means under a SharedLicense license
Your SharedLicense license itself is not affected — this is a change in cPanel & WHM software, not in licensing. Apply it on every affected server: sudo /scripts/upcp --force. Licenses keep working through updates; nothing needs re-issuing or re-activating.
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.
