Recovering from backup

In the event of a disaster, it is important to restore existing backups in whole or in part as quickly and easily as possible.

To start such a restore, you must first select a backup job on the left side of the main menu. From this selected job, data can then be restored from existing backup points or live backups.

After selecting a job you can start the restore process by clicking on this button:

A new window opens with adjustable recovery options:

The following can now be set in this view:

• Restore type: Here you can set what type of restore should be carried out. Further information on this can be found below.
• Source VM: Since a backup job can consist of several virtual machines, you can select which machine should be restored here.
• Select restore point to restore from: Here you must select a backup point or a LiveBackup to which the restore should be started. If a live backup is selected, the user is immediately given the opportunity to select a more precise point in time for the restore using the slider:

After clicking on “Start Restore” the restore process begins. Please note the recovery details for the individual restore types:

nxmBackup distinguishes between four restore types:

1. “Full virtual machine restore”: The selected virtual machine will be completely restored. Attention: An existing virtual machine with this name will not be overwritten; only the machine's required files will be stored in a selectable path. The VM can then be imported manually into HyperV. The storage path must be on a local storage medium and can be selected in the window that opens: After clicking on “Start restore” this begins and a status window reports on the progress:
2. “Full virtual machine restore to HyperV”: This restore option is identical to Full VM Restore. However, after the restore is complete, the virtual machine will be imported into HyperV. An existing virtual machine with this name will not be overwritten. The restored machine has the suffix “_restored” in HyperV Manager.
3. “Guest files restore”: The entire virtual machine is not restored here, but individual files can be retrieved from the backup. Attention: This restore type only works with virtual machines or virtual hard drives that are formatted with NTFS, FAT or FAT32. These are typically all Windows and Windows server installations. If the virtual machine uses more than just one virtual hard drive, a hard drive selection dialog will be displayed in the next step: Clicking “OK” starts the recovery. The source backup is now checked and loaded. After a short wait, a file selection dialog appears containing the contents of the virtual hard drive from the source backup. In the upper part of the window you can switch between the individual readable partitions of the virtual hard drive. Right-clicking on a file or folder can start a file download. The download then contains the selected file or folder in a zip-compressed form. Once the process is complete, it should be ended by clicking on “Stop restore”.
4. “LiveRestore”: BWith LiveRestore, the virtual machine can be temporarily started from the backup. The virtual machine is not completely restored, but only selected, necessary parts of it. After a short wait, the following message appears: This temporarily restored virtual machine can now be seen in the HyperV Manager with the suffix “_LiveRestore”. This VM can now be started manually. By default, nxmBackup disconnects this machine from the network to avoid problems with the network infrastructure. The performance of this machine depends on the I/O speed of the backup source. When work with this temporary machine is finished, the “Stop LiveRestore” button should be clicked within nxmBackup. The machine will now be automatically shut down and removed from HyperV. Attention: All changes made within this virtual machine will be lost. This machine is to be viewed as a pure information system.
