dattobd version 0.11.8

Bug Fixes:

  • Linux Agent Backups on Production: Fixed an issue where backups were not being created for Linux agents on Ubuntu 20.04 and 22.04. Backups now function correctly for Ubuntu 18.04, 20.04, and 22.04.
  • Kernel Panic on Reboot with Specific Kernel Versions: Resolved an issue where systems running kernel version 5.15.0-94-generic (and related versions) experienced kernel panics during reboot after installing the latest Datto Linux Agent (DLAD). This fix ensures: Systems can now reboot gracefully without user intervention. Compatibility with Docker installations, preventing kernel panics on affected systems. Improved stability on Ubuntu 22.04 with the specified kernel versions.
  • Incremental Backup Fails to Capture Changes: Fixed an issue where incremental backups did not capture changes made after a full backup. This included scenarios where new files added or files deleted after the full backup were not reflected in the subsequent incremental backup.

Known Issues:

  • Backup Resumability for Linux: Temporarily disabled for Linux DTC Agent (EBWDR) on Ubuntu 18, 20, 22.
  • On some operating systems, a differential merge may be incorrectly triggered following a soft reboot or shutdown.
  • A differential merge sometimes occurs after reboot due to an undersized COW file, leading to overflow.
  • The Datto Partner Portal may occasionally display a failed screenshot verification, even though the backup was successfully created and virtualized correctly.
