DattoDB 0.12.1 - May 16, 2025

New Features:

  • The Datto Linux Agent now officially supports SUSE Linux Enterprise Server (SLES) 15 SP5 and SP6.

Bug Fixes:

  • Backup Failures and Hung Processes on EXT4 Filesystems: Fixed an issue where backups could fail mid-process on certain Linux distributions (Debian 11, Ubuntu 18.04/20.04/22.04 with kernel versions such as 5.3.x and EXT4). This issue often left a hung datto_snap_cowX process, preventing future backups.
  • CentOS 7.3 Installation Failure: Resolved a dattobd kernel module build failure on CentOS 7.3 using kernel 3.10.0-514.el7, enabling successful agent installation.
  • Virtualization and Restore Failures – XFS Filesystems: Fixed issues preventing virtualization and restore operations from completing on systems configured with XFS.
    • Ubuntu 24
    • Debian 12
    • Red Hat 9.5 , Alma 9.5 , Rocky 9.5

DattoBD hotfix 0.12.0 - February 27, 2025

New Features:

  • Support for Debian 12: Added compatibility with Debian 12, enabling our product to support the latest enterprise Linux distributions. This update broadens our market reach and enhances usability for customers adopting Ubuntu's most recent release.
  • Support for Ubuntu 18.04, 20.04, and 22.04 Hardware Enablement (HWE) Kernels:
  • Added compatibility with Hardware Enablement (HWE) kernels for Ubuntu 18.04, 20.04, and 22.04. This ensures broader hardware support and improved performance on systems using the latest kernel updates provided by Ubuntu’s HWE stack.

Known Problems:

  • On Ubuntu 18.04 systems running kernel 4.15, sometimes backups after a system reboot are incorrectly processed as differential merges rather than incremental backups.

Bug Fixes:

  • Resolved an issue where stopping the agent service triggered unnecessary warnings related to COW file closure. This fix reduces log clutter and improves log readability.
  • Fixed a problem preventing DLA from booting when Logical Volume Manager (LVM) groups spanned multiple disks. This ensures proper initialization and system functionality on affected configurations.
  • Addressed an issue causing kernel panics on reboot for Red Hat Enterprise Linux (RHEL) and derivative distributions using DLA. This fix improves system stability and prevents unexpected crashes.
  • Resolved a conflict where installing both DLA and Docker on a Linux system caused Docker commands to hang, leading to a kernel NULL pointer dereference. This fix ensures smooth coexistence between DLA and Docker.
