Troubleshooting VMware backups

Note the following when you perform a VMware backup that protects an application:

  • The Application State Capture (ASC) job contacts the NetBackup client on the guest virtual machine and catalogs the application data for recovery.

  • One ASC job is created per VM, regardless of which applications are selected in the policy.

  • ASC messages are filtered based on the ASC job details in the Activity monitor.

  • Failure results in the discovery job or parent job exiting with Status 1.

  • If you enable recovery for a particular application but that application does not exist on the VM, the ASC job returns Status 0.

  • bpfis is run and simulates a VSS snapshot backup. This simulation is required to gain logical information of the application.

Table: Issues with using a VMware policy to protect databases

Issue

Explanation

A database backup fails.

Databases are cataloged and protected only if the configuration is supported for VMware backups.

See Limitations of VMware application backups.

NetBackup is installed on an excluded Windows boot disk. The ASC job detects this type of disk and treats it like an independent disk. Do not select the Exclude boot disk option if NetBackup is installed on the boot drive (typically C:).

ASC job produces a status 1 (partially successful).

You selected databases for backup that exist on both supported and on unsupported disks. See "A database backup fails" for unsupported disk information.

The Application State Capture (ASC) job fails and the databases are not protected.

When the ASC job fails, the VMware snapshot or backup continues. Application-specific data cannot be restored.

You disabled the Enable virtual Machine quiesce option.

Database objects are on a VHD disk. No objects in the backup are not cataloged, including those that do not exist on the VHD.

You excluded any data disks from the VMware policy, on the Exclude disks tab. Be sure that any disks that you exclude do not contain database data.

The VMware disk layout has changed since the last discovery. In this situation, you must force NetBackup to rediscover virtual machines by lowering the value of the Reuse VM selection query results for option. See the NetBackup for VMware Administrator's Guide.

You cannot use a VMware incremental policy to protect Exchange Server. However, the VMware backup job is successful.

You can recover the entire virtual machine from the backup, but you cannot recover the databases individually.

You did not select the Application protection option Microsoft Exchange Server on the VMware tab in the policy, which allows recovery of the databases from the virtual machine backups.

Transaction log backups fail.

You must first perform a full VMware backup without log truncation (Truncate logs option).

The Exchange databases are not quiescent.

Neither the Veritas VSS Provider nor the VMware VSS Provider was installed at the time of backup. The recovery of the Exchange database may require manual steps using the Exchange ESEUTIL utility.

GRT live browse error for a VMware image that supports the restore of application data.

The VMware backup did not include the volume where Exchange is installed.

You may encounter problems if you select VM hostname for the Primary VM identifier. Use VMware display name instead.
