Changes compared to 22.5.1

Enhancements

  • Support fallback domain controllers when configuring LDAP connection for administrators

Comet Server supports using external authentication sources for admin accounts. If you have a highly-available LDAP server infrastructure using multiple servers, such as an Active Directory failover cluster with primary/fallback domain controllers, you are now able to configure multiple LDAP server addresses in Comet Server. When an admin user tries to authenticate at the Comet Server login screen, if a connection to the first entry on the list fails, Comet will try the remaining entries on the list before denying the authentication attempt.

  • Update Thai translation

  • Improve handling of temporary files on Synology devices using the SPK client installer

During backup jobs, Comet saves some temporary files in the system temporary directory. In the Synology DSM operating system, the default directory for temporary files (/tmp) is a RAM disk. With this change, Comet switches to use a custom temporary directory. This reduces the RAM requirements for running Comet Backup on Synology devices, meaning that large backup jobs on RAM-constrained Synology devices will no longer cause slowdown or freezes due to running out of RAM.

Thank you to our partners for getting the Chinese (Traditional) localization started! The best-quality translations come from our customers, who better understand the software and the backup industry. We appreciate any translation assistance that is offered.

If you want to correct a translation in Comet, or if you want to translate Comet into a new language, further information is available via CometBackup/translations at GitHub.

This release comes with two key improvements to server self backup. Using the new slider component you can select 'faster' or 'smaller' to optimize the compression levels for the backup. A new option has been added to exclude the job database from the Comet Server self backup. It is best practice to keep regular backups of your comet server. Some very large databases can cause this to be a high cpu operation. In this case, we recommend having two backup schedules, one very regular backup that excludes the job database and another less regular backup that includes all databases.

We have also improved the onboarding experience for DSM-7. There is added guidance on how to configure permissions in the DSM 7 Synology SPK for the Comet client

New Features

  • Feature: Add Chinese (Traditional) language translation for client-facing text

Changes compared to 22.3.5

New Features

Comet Backup supports many different cloud storage providers (e.g. SFTP or S3-compatible) if you bring your own storage credentials. If you have configured Comet Backup to back up directly to a cloud storage provider, you should avoid reusing storage credentials across customers. For each customer, you should either create new cloud storage credentials manually; or proxy the data through Comet Server Storage Role; or ideally, have Comet Server allocate new cloud storage credentials automatically. Previous versions of Comet Server supported this "Requestable" provisioning for Backblaze B2, Wasabi Cloud Storage, and custom HTTP integrations. The latest version of Comet Server extends this support to Amazon AWS and to custom IAM-compatible cloud services.

  • Feature: Allow selecting Amazon AWS as a Requestable storage target

  • Feature: Allow selecting "Custom IAM-Compatible" as a Requestable storage target

New Features

New Features

  • Add the new schedule option "If last job was Missed" to allow a backup job to run as soon as the Comet client is reconnected when there are missed jobs

You can now select "If last job was Missed" from the schedule dialog. When a device re-connects to the server and detects that it has recently missed a backup, it will immediately start a new backup job. This replaces the previous option "When PC starts, if last job was missed". The "If last job was Missed" option bypasses any issues with fast startup, hibernation or sudden power off interrupting a backup schedule.

Changes compared to 21.12.0

  • Deprecation: Comet Server no longer supports Windows Vista or Windows Server 2008.

Windows Server 2008 R2 is still supported for both Comet Server and the Comet Backup desktop app.

  • Deprecation: Removed support for U2F for two-factor authentication for admin users due to the impending removal of U2F from browsers (see !https://groups.google.com/a/chromium.org/g/blink-dev/c/xHC3AtU_65A). Existing U2F 2FA will be automatically migrated to use WebAuthn when the Comet Server instance is upgraded; this requires no action on an admin's part, and the same U2F devices can continue to be used.

New Features

  • Added support for WebAuthn for two-factor authentication for admin users, including support for Windows Hello Face / Fingerprint / PIN, Android Safetynet / Fingerprint and other Hardware Security Keys
