Configuring a VMware backup policy to protect Exchange Server

Through a VMware backup policy, NetBackup can create full application-consistent backups of the Exchange databases that reside on a virtual machine. Granular Recovery Technology (GRT) is always available with the VMware policy and optionally you can use NetBackup Accelerator. VMware policies let you exclude certain virtual disks from the VMware backup. If you want to exclude specific Exchange components, use a MS-Exchange-Server policy.

To truncate logs, you must first perform a full VMware backup without log truncation. When this backup is complete, then enable log truncation in the policy.

More information on Accelerator is available:

See About policy attributes.

See the NetBackup Administrator's Guide, Volume I.

To configure a VMware backup policy to protect Exchange Server

Open the NetBackup web UI.
On the left, click Protection > Policies.
Add a new policy or open the policy that you want to edit.
Click the Attributes tab.
- From the Policy type list, select VMware.
- In the Policy storage list, select a disk storage unit.
  If you want to use NetBackup Accelerator, select a supported storage unit type. The NetBackup device mapping files list all supported storage types.
- If you want to use NetBackup Accelerator, click Use Accelerator.
  Accelerator uses the initial full backup to establish a baseline. Any subsequent backups that are performed with Accelerator can run significantly faster. You may want to create an additional policy schedule that enables the Accelerator forced rescan option. This option establishes a new baseline for the next Accelerator backup.
  Perform block-level incremental backups is automatically selected and grayed out. On the VMware tab, the Enable block-level incremental backup option is also selected and grayed out.
On the Clients tab, do the following:
- Click Select automatically through VMware intelligent policy query.
- From the NetBackup host to perform automatic virtual machine selection list, select the host you want to use.
- Use the Query builder to create the rules that select the virtual machines you want to back up.
On the VMware tab:
- Select the Primary VM identifier to use to catalog the backups.
- Select Enable file recovery from VM backup.
- Locate Application protection and click Microsoft Exchange Server.
  This option allows recovery of the databases from the virtual machine backups. If this option is disabled, you can recover the entire virtual machine from the backup, but you cannot recover the databases individually.
- Do not enable Truncate logs at this time. You must first perform a full backup without log truncation, described later in this procedure.
If you want to exclude certain disks from the VMware backup, click the Exclude disks tab.
NetBackup excludes those disks from the VMware backup that protects Exchange Server. Be sure that any disks that you exclude do not contain database data.
Click Save to save the policy.
If you do not want to truncate transaction logs, no further action is necessary.
If you want to truncate transaction logs, continue with step 9.
Perform a full backup without log truncation.
When the backup completes, open the policy that you created in step 1.
Click the VMware tab.
Locate Application protection and click Microsoft Exchange Server. Then click Truncate logs.
For Exchange Server, this option truncates the transaction logs when the VMware snapshot of the virtual machine is complete.
Click Save to save the policy.
Perform a full VMware backup.
