One of the most effective ways to protect virtual machines is by leveraging the primary storage arrays on which the VMs are stored. This method uses array snapshots to create quick copies of the file system. These point-in-time copies of the data are then moved to secondary storage for archival. Using storage for backups has the following advantages:
Many backup products support leveraging array snapshots to perform backups, but using NetVault has added advantages:
We will look today at how to use SnapVault plug-in with VMware virtualization. Complete details can be found by downloading NetVault: BackupSnapVault Manager Plugin User’s Guide from support.quest.com.
After you have the NetVault backup server configured, and SnapVault plug-in installed, perform the following steps to configure filers with NetVault server
options snapvault.enable on options SnapVault.access <secondary>
options snapvault.enable onoptions SnapVault.access <Primary>
That’s it. Now you are using the power of your NetApp storage to backup your VMs. Restore Restores are the easiest part of the whole setup! There are no messy storage adapter rescanning or datastore additions necessary! Just open the NetVault: Backup GUI and go to the SnapVault plug-in. You will be able to see your backup volumes that you used to establish the relationship. Because the backups are stored in the native format, you can view all directories under which the VMs are stored.If you are restoring the VMs to an alternative filer, you can start restoring right away. If VMs are to be restored to original filer, then you first have to release the relationship between the primary and secondary volumes. Using this method:
The restores happen between the filers and not the servers, thus conserving production resources.
Once data is restored, you will have to import the VMs into the vCenter inventory. Since these are the same VMs that exist in the vCenter database, you will not have to re-GUID them.
