Retrieving a File
This topic describes how to retrieve a file from a stored backup. At this time, restoration is holistic - the full user disk is restored, the base disk is merged with the differencing disks in order by age up to the selected restore point. To restore a file, the VM (virtual machine) is reset to the state it was in when the file existed. The user then copies the file from the VM. The VM is returned to its current state, and then the file is copied back to the up-to-date NxTop.
To retrieve a file for a VM:
Step One
The User contacts the NxTop Administrator, requesting that the VM be set to an earlier restore point. The user needs to provide the VM name, and the date to use as a restore point.
Step Two
The NxTop Administrator opens the Users branch of the navigation tree, then selects the User.
The User branch lists any assigned VMs.
Step Three
Select the VM to restore and click the Backups tab.
The list of backups for that NxTop appears.
Step Four
The Administrator clicks the Modify action, and fills the checkbox for the backup to use as the restore point. The checkboxes above the selected point are emptied.
Step Five
The Administrator clicks Save 
The next time the user's computer contacts NxTop Center,
- Backup processing is suspended
- Updates are suspended
- The NxTop user disk (and other files included in the backup, and the system disk for custom VMs) is set back to its state as of the restore point. Changes dated after that restore point are ignored.
Step Six
The user sees that a restore point has been set on the NxTop, and restarts the VM.
The VM's user disk (and system disk on a custom VM) is restored to its state as of the restore point.
Step Seven
The User finds the file(s) from the earlier restore point that they want to keep, and copies these files to another location off of the VM user disk (a network share or other media, or even the local disk (L: drive).
The User shuts down the VM.
Step Eight
The NxTop Administrator selects the user's VM again (see step 2) clicks the Modify action, and clicks any filled checkbox on the Backup tab, clearing all the checkboxes.
Step Nine
The Administrator clicks Save, clearing the restore point.
The next time the user's computer contacts NxTop Center,
- Backup processing is re-enabled
- Updates are re-enabled
- The NxTop is set to its state as of the last backup. The differencing disks (backups) between the previous restore point and the current restore point as re-applied.

The VM is returned to its current state when it is restarted after the restoration is received. The file can then be copied back to the VM user disk.
