Environment

  • N-able RMM

    • Backup & Recovery
  • N-able N-central
    • N-able Backup
  • Virtual Disaster Recovery

Solution

  1. The Backup Manager restore in progress panel will show the file it is currently restoring, Take note of that.
  2. Check the application logs locally from http://localhost:5000/logs/app
  3. Search for the file that is being restored and you will likely see the following:
    • [BackupQueueHandler] Leaving restore of <filename>
  4. This means the restore of the data is complete but it is still doing some work. Likely merging disks. Look for the following line:
    • [VhdApiWrapper] Start merging of difference disk to parent.
  5. This means the disks are being merged. It can occasionally take a long time.
  6. Check the device to see if you can find evidence of it still being merged.
    • From your Hyper-V Manager you might see "Merge in Progress" status message.
