Changes compared to 26.2.3
Notice
Gradient PSA integration retired
The Gradient PSA integration has been retired. Existing configurations are preserved and clearly marked as deprecated in the UI, with a startup warning to help administrators plan any necessary migration.
New Features
Proxmox VM and LXC template backup and restore
Proxmox customers can now protect their VM and LXC templates — with full backup and restore support. This closes a meaningful gap in Proxmox coverage, ensuring the building blocks of an environment can be recovered just as reliably as live workloads.
Zero-touch device registration for 2FA-enabled users
Administrators can now register devices on behalf of users who have 2FA enabled, using either lobby mode or an install token, without requiring the user to be present or share their TOTP code. This removes a key friction point in enterprise and MSP deployments, enabling true zero-touch device provisioning.
Enhancements
Disk image backup support for Ubuntu 25
Customers running Ubuntu 25 can now take full disk image backups, keeping pace with the latest release cycle.
Auto-add Cluster Manager target when creating Storage Templates
When setting up a Storage Template or replication target, administrators are now prompted to simultaneously register the destination as a Cluster Manager target — eliminating a common multi-step setup gap.
Streamlined licensing during Comet Core installation
The Comet Core installer now presents a streamlined licensing experience showing only the serial license key option.
/run and /var/run excluded from Unix Files and Folders backups by default
Files and Folders backups on Unix systems now automatically exclude /run and /var/run by default. Excluding these paths out-of-the-box improves efficiency and reduces unnecessary data capture without any user configuration.
Improved error messaging for Backblaze Storage Vault creation failures
When a Backblaze-backed Storage Vault fails to be created, users now receive a clear, actionable error message instead of a generic server error — reducing troubleshooting time and support overhead.
