Bug Fixes

Agent Interaction with "Partially Loaded" Driver: Fixed an issue where the agent failed to back up due to interacting with a "partially loaded" driver.

Bug Fixes

Snapshot Handling: Fixed an issue causing missed file system changes and corrupted backups due to simultaneous creation of shadow copies by other software. Our agent now handles these situations better, ensuring reliable backups.

Bug Fixes

Blue Screen Prevention: Resolved an issue that could cause a Blue Screen showing 'Inaccessible Boot Device' error. Agent logic has been updated to monitor the state of the cbtfilter driver. If the filter driver has been blocked, all backups will run as a diffmerge until the installation is completed successfully and the system is rebooted. Please make the recommended adjustments in your AV/EDR solution as detailed here.
Backup Timeout Fix: Fixed an issue where Endpoint Backup agents could time out prematurely during backup finalization, leading to failed backups.
Restore Point Reliability: Addressed a problem in Endpoint Backup Agents that could result in unrecoverable restore points and bluescreens during screenshot verification. To ensure backup integrity, impacted assets may promote the next backup to a diffmerge to maintain data consistency after this update.
Startup Stability for Azure Agent: Resolved a startup crash in the Datto Backup for Microsoft Azure agent.
