Agent Version 3.0.19.1

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.

To ensure backup integrity, impacted assets may promote the next backup to a diffmerge to maintain data consistency after this update.
