Environment

  • Datto Endpoint Backup

Description

  • Releases may consist of Device updates, Agent Updates, or both as specified. Device updates represent the Datto Cloud software, whereas Agent updates represent the Agent software on the protected machine.
  • Datto pushes updates out on a rolling basis. You may not be updated immediately upon each new release. Update windows will vary, but are generally completed within one to two weeks of the initial release date.
  • When new releases become available, they are automatically pushed out and require no partner intervention unless otherwise noted.

Release Notes 3.0.25.0 - 2024-10-16

New Features

  • HashCache Integration for Faster Diffmerge Operations: We’ve introduced HashCache to optimize diffmerge operations during backups. This enhancement reduces resource consumption, including CPU, Disk IO, and Network IO, by approximately 60%, significantly improving performance and reducing operation times.

Bug Fixes

  • Increased Backup Connection Timeout: Fixed the issue with the default Datto endpoint backup connection timeout being too short, causing potential failures in slower network environments. Now, the timeout has been increased to improve backup reliability.
  • DWA Uninstaller Removing Unrelated Files: Fixed the issue with the DWA uninstaller removing all contents within C:\\Program Files\\Datto, including unrelated files. Now, the uninstaller only removes Datto Windows Agent files, leaving other files intact.
  • Datto Endpoint Backup Agent Installation on Unsupported OS: Fixed the issue with the Datto endpoint backup agent allowing installation on non-supported operating systems, causing potential compatibility issues. Now, the agent correctly blocks installation on unsupported OSes to ensure proper functionality.
  • EB Agent Crashes Due to Integer Division by Zero: Fixed the issue with the EB Agent crashing due to an integer division by zero, causing unexpected interruptions in backup processes. Now, the agent operates reliably without crashing during backups.

Release Notes 3.0.21.0 - 2024-07-22

Enhancements

  • Datto Windows Agent now collects more details about Disk health, NTFS and VSS logs; upcoming Siris and portal updates will alert for unhealthy local volumes.

Bug Fixes

  • Fix for occasionally hanging backups related to unstable network.
  • Fixed incorrect display of estimated backup completion time in the system tray.
  • Fixed an issue where backup progress could exceed 100% in the Datto portal, ensuring accurate progress display.

Release Notes 3.0.19.12 - 2024-06-26

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.

Release Notes 3.0.19.11 - 2024-06-07

Bug Fixes

  • Tracking During Pauses: Fixed a bug where changes made during pause states weren’t tracked. Our improved resumability implementation now captures and sends all new blocks, even during pauses, keeping backups up-to-date.

  • Fixed the issue with Memory Corruption in Empty Space Excluder: Resolved problem causing memory corruption due to undefined behavior during memory copying.

  • Fixed the issue with Improper Reading of Resume File with Byte Value 26: Corrected file reading mode to prevent premature end-of-file (EOF) when encountering byte value 26 in the resume file.

Release Notes 3.0.19.9 - 2024-06-04

NOTE  A manual agent update will need to be performed, before the automatic agent update process will resume. For more information please refer to: Manual Update Required for Datto Windows Agents

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.
