Trial backup for VMware

Trial backup for VMware lets you perform approximate validations for the backup configuration. Trial backup support for VMware is only available through an API call.

A trial backup operation for a virtual machine performs certain operations as:

  • Discovery

  • Validation of credentials

  • Snapshot

  • Mapping of a few files (if you have selected the enable file recovery option in the policy).

  • Test the transfer of limited bytes (to the media server) of data per disk of a virtual machine.

You can use the following API with the input parameter trialBackup: true to initiate a trial backup for a VMware policy. Before you use the trial backup API, the required policy configuration must be defined in the policy created.

API : /admin/manual-backup

Method : POST

Example: Request body

{
 "data": {
               "type":"backupRequest",
               "attributes": {
                   "policyName": "vmware_test",
                   "trialBackup" : true
               }  
     }
}

The backup job displays as Trial Backup.

Note the following:

  • The parameter trialBackup is optional and its default value is false.

  • A trial backup is not recoverable. The Image Clean up job does the cleanup of test data which is transferred during the trial backup operation.

  • The trial backup functionality is only supported for a VMware policy of VADP (VMware vStorage API for Data Protection) based backups. It does not validate application integration with Microsoft Exchange, SharePoint, and SQL server.

  • VMware agent resource limits apply to trial backup.

  • A trial backup consumes resources like querying the vCenter for discovery and there can be short-lived snapshots.

  • A trial backup doesn't affect existing schedules or incremental backup chains. However, it may affect VMware resources like the vCenter for discovery and snapshot.
