Restoring virtual machines

This procedure explains how to restore or retrieve one or more virtual machines from backup or archive (respectively). Note the following:

l Multiple virtual machines may be restored from a single TSM server only.

l If you are restoring to a standalone ESX/ESXi host, VMB must be configured to connect directly to that host. Check settings on the vCenter Server tab of the STORServer VMB Settings dialog box. Only virtual machines that were backed up using the VDDK backup technology and changed block tracking (CBT) can be restored to a standalone ESX/ESXi host.

l If the virtual machine that is being restored is a vCenter Server, refer to the STORServer white paper titledProtecting and Restoring a VMware vCenter Server Virtual Machine with STORServer Virtual Machine Backupfor instructions.

l If the virtual machine that you want to restore is not listed on the Clients tab, see Restoring a deleted virtual machine clientfor further instructions.

l If the virtual machine was backed up or archived using the older VCB backup technology, seeRestoring and retrieving from VCB backups and archives.

l You can opt to validate full machine backups instead of actually restoring the virtual machines by using the Perform data validation only option in theRestore Virtual Machines dialog box. This option is valid only for full machine backups created with VDDK backup technology.

To restore or retrieve one or more virtual machines:

1. On the Clients tab, select one or more virtual machine clients and click Restore or click the down-arrow on the Restore button and select Restore Virtual Machines on the submenu.

Tip! To make a long list of clients more manageable, use the Show clients on host feature to filter the list by ESX/ESXi host, or click the appropriate column head to re-sort the list by name, ESX/ESXi host, or last backup, for example.

2. In theOn-Demand Restore - Virtual Machines or Disks dialog box, click Next to use the default values unless you need to:

n Specify a different TSM server. (You may be prompted to log on.)

n Retrieve virtual machines from archive. (The default setting is to restore from backup.)

n Restore an older version of one or more selected virtual machines. (Latest is selected by default.)

When you select Date range and specify a date range, the backups or

archives that occurred during that period are listed in the next dialog box. Both active and inactive files are included by default. You must clear the Include inactive files check box to omit inactive files.

3. In theRestore Virtual Machines dialog box:

NOTE! Values that you set during this procedure (network, ESX host, and datastore, for example) are applied to all virtual machines that are being restored. The default "Unchanged" value retains original settings on all selected virtual machines.

a. If you specified a date range in the previous dialog box, there may be multiple versions of selected virtual machines listed. Select one version for each virtual machine that is being restored.

Tip! Entries in the Type column indicate which backup technology was used and the type of backup/archive that was performed. See theRestore Virtual Machines dialog boxsection for a list of entries that may appear in this column.

b. Verify settings for the newly restored virtual machines:

n These settings apply to ALL virtual machines that are being restored. The default "Unchanged" value retains original settings on each selected machine.

n When restoring a virtual machine that already exists on the specified ESX/ESXi server, select the Delete and replace existing virtual machines check box or specify a new name for the restored machine. To rename multiple virtual machines, add a prefix, suffix, or both.

n When restoring virtual machines to a standalone ESX/ESXi host, be sure to select that host in the ESX host box, and a Network and Datastore that are valid for that host.

c. Click Start.

You can monitor the status of this on-demand job from the Status tab.

NOTE! Do not attempt to access or use the restored virtual machines until the restore operation has successfully completed.

Notes... 

l When restoring or retrieving virtual machines using VDDK backup technology, you may notice that none of the restore/retrieve candidates match the last backup date shown on the Clients tab. This occurs when the last backup or archive was

incremental rather than full. With VDDK technology, virtual machines can only be restored from a full machine backup.

l When restoring or retrieving a virtual machine that was backed up or archived using VDDK backup technology and changed block tracking (CBT), if you select a

differential backup, STORServer VMB restores the latest base backup first, followed by the differential backup.

l When restoring to a different ESX/ESXi host, make sure that host is running a version of ESX/ESXi software that is the same or newer than that of the original host (the host on which the virtual machine resided when it was backed up or archived).

Otherwise, the restore will fail if features that were enabled during the original backup (CBT, for example) are not supported by the target host.

l Virtual machines that were backed up with the TSM for VE backup technology can be restored directly from the VMware vSphere Client using the Data Protection for VMware vCenter plug-in, an optional TSM for VE component.
