NovaStor DataCenter 

Notable Resolved Issues

• Hyper-V: Backup Type "All VMs" does not start up.
  Creating a Hyper-V backup job to a GIR pool that includes “All VMs” did not start if the job was configured for incremental backup. Backup jobs that do a full backup were not affected.
• Hyper-V GIR pool restore fails if restored to root path
  Restoring a Hyper-V backup from a GIR pool to a root path (e.g. c:\) failed with an error. Now the virtual disks are restored to the selected root path and the configuration is put in a directory “Configuration”.
• Hyper-V restore from alternate pool does not work
• Hyper-V GIR pool restore from alternate pool passes wrong pool ID
• VMware backups end prematurely, but VMware.exe still runs.
  A log truncation issue has been fixed. In some cases logs of jobs (e.g. backup) were fetched prematurely. This was leading to jobs being marked erroneously as failed even though the backup has been successfully completed but the user were not able to restore from that backup.
