Committing a Restore Point
The NxTop Administrator can select the date of the backup used for a restoration (set a restore point). Committing to a restore point:
- sets that user's VM (virtual machine) to reset to that committed point
- deletes all later differencing disks; the collection of differencing disks starts again from the restore point
Committing a restore point deletes later differencing disks used to compose a backup. If the user is restored or assigned to a new computer, the restore point is the backup data used. Backups are then added to chain from that restore point.
In the image below, a restore point of June 19 is committed, and the backups for June 20th and June 21st are removed. Subsequent backups would build on top of the June 19th backup.

See Backup and Restore for more information.
To commit to a restore point for a VM:

Step One
Open the Users branch of the navigation tree, then select the User.
The User branch lists any assigned VMs.
Step Two
Select the VM to restore and click the Backups tab.
The list of backups for that VM appears.
Step Three
Click the Modify action.
The Delete Backups pop-up appears. It lists each backup (restorable point) for that user's VM, the size of the differencing disk for that file (Backup Size) and the total size of the accumulated backups (Total Size).
Step Four
Fill the checkbox of the backup to use as the restore point.
That backup and those dated earlier are selected with checkboxes. Later backups have empty checkboxes.
Step Five
Click Save.
The user should verify that this is the correct backup, and that he or she wants to continue form this point forward. Once the restore point is committed, the later backups are deleted.
Step Six
Click the Commit Restore Point action.
Step Seven
Click Yes in the confirmation pop-up to set the restore point for that user VM to the selected date, and to delete later differencing disks.
The unchecked backups are deleted. This user VM is restored as of the date of the committed Restore Point. All backups dated later than the Restore Point are deleted. New differencing disks start accumulating from the committed Restore Point.
