Prerequisites and limitations of VMware agentless restores
You must provision VxUpdate packages for all platforms for which you have virtual machines where you want to perform agentless recovery.
You must have an account with administrator or root permissions on the target virtual machine.
The target VM is where the files are recovered. It must be powered on and have VMware Tools installed.
The default staging location on the target VM is
%TMP%for Windows and the root directory (
/) for Linux.
The staging location must exist on the target VM file system.
You must have the latest version of VMware Tools installed to perform agentless restores.
Agentless restores to Windows target VMs can fail if you use an account other than the built-in Administrator for Windows Guest OS account as the . The restore fails because is enabled. More information is available:
VMware agentless restores can only be used for the restore of files and folders.
In some instances, when you perform an agentless restores, orphaned VMs starting with
NB_are left behind. Using the ESX server credentials to perform the restore on the target VM even though the vCenter manages the ESX server can cause this condition. This condition is a known limitation of VMware. To resolve the problem, register the vCenter in NetBackup and use vCenter credentials for backups and restores. The orphaned VMs starting with
NB_can be removed from inventory manually by logging into the vCenter using VMware vSphere Client.
Restore job fails if NetBackup is unable to use the directory that is specified in the TMP or TEMP environment variable as the staging directory.
Restore job fails if NetBackup does not have sufficient privileges to the staging directory or if there is insufficient space in the staging directory.
If you selectand options, you risk an incorrect restore if it contains multiple files with the same file name. In this case, the last file that is restored is the one that is present when the restore completes.
If you selectand you do not select , the restore succeeds, and the first file that is restored is present when the restore completes. To prevent this issue, do not select when restoring multiple files with the same name.
Theand options are only applicable to files. They are not available for directories.
Multiple restore jobs to the same VM are not supported. The user must start another job as needed for that VM once the first restore job for that VM has completed.
If a backup and a restore occur simultaneously on the same VM, one or both jobs can have unexpected results. If a backup or a restore exits with a non-zero NetBackup Status Code, one possible cause is simultaneous jobs occurring on the same VM.
Veritas does not recommend VMware agentless restore if a NetBackup client already exists on the target VM. The NetBackup administrator must use the agent based restore in such cases.
Veritas supports SLES, Red Hat, and Windows as the guest operating systems for the target VM.
