About Nutanix AHV agentless files and folders restore
NetBackup 9.1 and later support Nutanix AHV agentless files and folders restore. It lets you restore individual files or folders to any target host. The target host can be a virtual machine hosted on AHV or other hypervisors or even a physical machine where the NetBackup client is not installed. This restore uses VxUpdate package of matching target host platform and deploys NetBackup recovery tool on the target host. Agentless files and folders restore performs clean-up of recovery tool and staging location after the restore process is completed. The recovery process uses a NetBackup host as a recovery host that has network connectivity with the target host. This recovery host can be either NetBackup server or a client.
Overview of the files and folders restore process
The NetBackup primary server receives input from either the NetBackup web UI or the agentless recovery API. The input is the files or folders for restore along with the target host credentials. The required credentials are:
Windows: User must belong to the local administrators group if UAC is disabled. If UAC is enabled, the user must be a domain user, added to the local administrator's group.
Linux: User must be a root or sudoer user having all permissions.
The primary server sends the requested data to the recovery host.
The recovery host confirms that it has the necessary VxUpdate recovery package to perform restore. If it's not available, the recovery host downloads the required package from the primary server that uses VxUpdate.
The recovery host copies recovery tool of VxUpdate package to target host. Linux recovery and target host use SSH protocol for recovery operation. Windows recovery and target host use WMI, SMB protocol for recovery operation.
The data stream file containing files and folders to be restored is staged at a staging location on a recovery host.
The file created on recovery host staging location is copied to staging location on a target host.
The recovery tool is invoked, and selected files or folders are recovered along with ACLs and metadata details.
NetBackup performs the necessary clean-up even if restore operation is successful or failed. All temporary files stored at the staging location on target host and recovery host are removed. However, in case of failures the evidence is collected from target host to recovery host collection with default configuration.
