Comet Backup Release Notes

Last modified: 2026 November 11

Comet Backup 1.5.12

2026 November 11

This release includes every change since Comet Backup 1.5.6. Servers that run Ubuntu® already received version 1.5.10 on 2026 October 20, so the changes under Backup model and disaster recovery (1.5.7 to 1.5.10) are already on those servers.

Backup model and disaster recovery (1.5.7 to 1.5.10)
  • CPANEL-54613: Backups now use a small fixed set of Protected Items per server: native MySQL® with every account’s users and grants, grouped home directories, and account passwords, keys and settings. Restores and disaster recovery work from both new backups and backups made before the upgrade. Backup runs recover from a backup agent restart and report their results accurately.
  • CPANEL-52332: The Activity tab lists each backup job’s activity.
  • CPANEL-55613: A server recovered with disaster recovery keeps its activation code, so it can still provision cloud storage.
Backups
  • CPANEL-57969: Excluding junk mail now excludes only Junk and spam folders. Previously, read messages in top-level mail folders were also left out of backups.
  • CPANEL-57978: Every backup job backs up its accounts’ home directories, including a manual run of a job that shares a grouped backup with other jobs.
  • CPANEL-57979: Custom exclusions in grouped home directory backups now match top-level names, **/name patterns, and absolute paths.
  • CPANEL-57968: A file that is renamed or removed while the backup reads it, such as a mail message that is marked as read, no longer fails the home directory backup.
  • CPANEL-57940: Unreadable files that do not matter, such as the LiteSpeed cache log, root-owned entries in a home directory, and a public_ftp directory with no permissions, now log a warning instead of failing the nightly home directory backup.
  • CPANEL-57953: A partial backup run now refreshes the disaster recovery point, so a recovery uses the newest snapshot.
  • CPANEL-57967: Before each run, the plugin checks its backup definitions on the Comet Backup server and corrects any that differ.
  • CPANEL-58098: A destination is marked as failed when its backup job never starts.
  • CPANEL-57614: Run summaries count an account as backed up only when its items were backed up.
  • CPANEL-58288: Nightly runs no longer warn that zero Protected Items were backed up for accounts that were removed and recreated.
  • CPANEL-57886: Fixed duplicate jobs and destination changes, kept restore data when a restore step fails, improved the grading of file backups and the tracking of restore jobs, and hardened the handling of local destination paths and temporary domains.
  • CPANEL-57875: Comet Backup no longer causes I want to umask(022) warnings when you create an account in WHM.
Restores and disaster recovery
  • CPANEL-57980: A restore of a grouped home directory to a different path now restores to that path instead of over the account’s live files.
  • CPANEL-58087: An in-place restore that reaches the account’s disk quota no longer overwrites existing files with empty files.
  • CPANEL-58038: Restores only offer recovery points that still exist in the storage vault, and the system checks the vault before it creates an account. A refused restore no longer leaves a partly created account.
  • CPANEL-58046: A full restore on a server with more than one storage vault fetches the account’s settings from the vault that holds the backup.
  • CPANEL-57930: A full restore no longer applies the settings of an earlier account with the same name from another backup job.
  • CPANEL-58083: An account whose backup job does not include Account Configuration restores in place, and the restore stops with a message if the account no longer exists.
  • CPANEL-57879: Native MySQL restores keep each database user’s assignments.
  • CPANEL-58273: Database restores keep the account owner’s MySQL privileges on hosts other than localhost.
  • CPANEL-58082: Restored MySQL logins follow the account’s current suspension status.
  • CPANEL-57952: After a restore, the plugin checks that the account’s DNSSEC keys, password and logins were applied.
  • CPANEL-58080: A restore no longer fails the whole account when only the DNSSEC step was skipped.
  • CPANEL-57932: Finding temporary domains after a home directory restore no longer stalls large restores.
  • CPANEL-58086: Restores no longer log temporary domain warnings for files that the account cannot read.
  • CPANEL-57931: The restore log now says why the system could not look up an account’s saved settings.
Interface
  • CPANEL-54266: On servers licensed directly through cPanel, WHM shows Comet Backup and a link to buy it in the cPanel Store before you purchase a license.
  • CPANEL-58032: The restore wizard lists accounts in seconds on servers with a long backup history.
  • CPANEL-58045: You can create a settings job for all accounts in seconds. Previously, the interface could time out.
  • CPANEL-58037: The multiple-accounts restore list and the Activity and Job History pages no longer show two scrollbars.
  • CPANEL-58233: Job names with accented letters or emoji display correctly, and error messages no longer show internal program details.
  • CPANEL-58047: Improved run summary accuracy and error messages.
  • The Comet Backup announcement banner no longer appears on WHM’s Home interface.

Comet Backup 1.5.6

2026 July 14

Bug fixes
  • CPANEL-54412: Request the less-often automatic-retention ruleset for dispatched backups and stop cancelling orphaned in-flight jobs, so overlapping retention passes no longer wedge the device with locked-by-device failures.

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.

Comet Backup 1.3.3

2026 April 23

Bug fixes
  • CPANEL-52790: Remove non-functional Get More Space button.

Comet Backup 1.3.2
