Alike v6.2 build 8403

Released: 1/22/2019

A stabilization and performance update. All A2 customers are encouraged to upgrade to this build.

Please note: this update requires operating system updates/packages to complete. The A2 will require internet access to perform OS updates (standard Ubuntu apt-get).


  • Increases core restore performance across all restore paths and provides increased stability for backend operations.*

Bug Fixes

  • Hardens resiliency of full restore to Xen. This restore path is now more tolerant of networking intermittencies, especially for long-running restores
  • Eliminates intermittent database lock issues in Data Engine
  • More reliable and improved handling of all Xen upload/download over HTTP/S. Improves stability of CBT and other operations.
  • Addresses 'Access denied' issues with full restore to Hyper-V
  • Resolves issue with Q-Hybrid second disk GPT. These now load correctly in the restoreFS FLR directories
  • Improves Q-Hybrid performance when protecting iSCSI drives
  • Resolves issue with S3 intermittencies and rebuilds through failsafe functionality
  • Fixed various UI typos and errors

Known Issues

  • "alike" user for RestoreFS does not always change password properly
  • LVM file-level restore not supported for RestoreFS (full restores are supported)
  • Deleting an entire VM from the UI will remove it to be lost from any configured jobs
  • Dashboard graph empty on first day after initial install and setup

*Please note: customers with the specialized "no_hc0" ABD installed to work around the XenServer driver issue will not receive all of the restore performance improvements.
