Comet Backup Release Notes

Last modified: 2026 June 10

Comet Backup 1.5.5

2026 June 10

Bug fixes
  • CPANEL-53785: Update WebPros remote storage when the Comet Backup license changes. Cloud storage provisioning is now available from the Destinations tab on storage-tier licenses, with re-authentication resume.

Comet Backup 1.5.4

2026 June 03

Bug fixes
  • CPANEL-53162: Stop Comet backups from consuming all local disk space while a backup runs.
  • CPANEL-49676: Apply the CPANEL-53254 resource-usage approach to the backup side so the plugin works correctly on v110.
  • CPANEL-53561: Ensure the outbound User-Agent is not inherited from the parent process.
  • CPANEL-53604: Fix restore backup options being hidden in the UI.
  • CPANEL-53706: Fail a Comet database restore when restorepkg errors out, and compute the restore –disable list from live modules instead of a static 134-era list.
Improvements
  • CPANEL-53411: Remove the credentials download warning.

Comet Backup 1.5.3

2026 June 02

Bug fixes
  • CPANEL-53589: Fix a scheduling race that caused first-run backup jobs with no prior run history to never execute.
  • CPANEL-53414: Correct the destination label from “WebPros Cloud” to “WebPros Storage” in Destination Management.

Comet Backup 1.5.2

2026 May 28

Bug fixes
  • CPANEL-53213: Fix restorable accounts disappearing from the multi-account restore interface when the backup job that created them is deleted.
  • CPANEL-53355: Fix backups hanging when the Comet Backup Server is slow to respond by bounding the create_backup_job call to its configured timeout.
  • CPANEL-53423: Guard orphaned-job cancellation against connectivity failures; fix backups hanging due to a problematic running_only query argument.
  • CPANEL-53585: Fix restore failures on Ubuntu caused by a shared socket after forking.
Improvements
  • CPANEL-53247: Narrow Comet API queries using GUID/SourceGUID/HasFinished filters and prevent concurrent backup runner instances.
  • CPANEL-53495: Improve the onboarding experience when no backups are present; open the backup wizard directly from the onboarding call to action.
