5 Quest NetVault Backup Plug-in for SnapMirror to Tape User s Guide 5 Chapter 1: INTRODUCING QUEST NETVAULT BACKUP PLUG-IN FOR SNAPMIRROR TO TAPE Quest NetVault Backup Plug-in for SnapMirror To Tape At a Glance Feature Summary SM2T Backups and NDMP Dump Backups Target Audience Recommended Additional Reading About Quest Software Contacting Quest Software Quest Support Quest NetVault Backup Plug-in for SnapMirror To Tape At a Glance NetApp's SnapMirror Software provides many benefits to system administrators, including reduced backup and recovery windows, instant access to mission-critical data, and file system replication at a local or remote site. Working in conjunction with the SnapMirror technology, Quest NetVault Backup Plug-in for SnapMirror to Tape (Plug-in for SnapMirror to Tape or Plug-in for SM2T) extends these benefits by enabling full volumes on NetApp Filers to be mirrored and backed up to tape. Tape mirror copies can be used as an alternative transport mechanism and provide long term, off-site archival storage for mirrored volumes. The plug-in's benefits are further extended when combined with the NetApp Snapshot Technology. Snapshots provide a backup function that allow user and application data stored on a Filer to be quickly and efficiently backed up with virtually no service disruption. Snapshots are stored on volumes residing on the same filer as the data being protected and provide a fast method of data recovery under normal circumstances. SnapMirror to Tape can be used to backup filer volumes containing snapshots on a periodic basis for disaster recovery purposes. In a disaster scenario where the entire filer is lost, snapshots can be recovered quickly and efficiently from the tape to ensure minimal interruption to operations.

13 Quest NetVault Backup Plug-in for SnapMirror to Tape User s Guide 13 Chapter 3: CONFIGURING PLUG-IN FOR SM2T Prerequisites Adding a NetApp Filer to Plug-in for SM2T Reconfiguring an Added Server Removing an SM2T Server Prerequisites Before you start the configuration procedure, make sure that the following requirements are met: Connect the Backup Devices Ensure that the backup device is properly connected to the NVBU Server, SmartClient or the NetApp Filer depending on the type of the Data Transfer Model in use. Add the NetApp Filer Add the NetApp Filer as an NDMP Server to the Plug-in for NDMP. For details on adding an NDMP Server, refer to the Quest NetVault Backup Plug-in for NDMP User's Guide. In a Filer-to-Filer Data Transfer Model, add both the target Filer and the Filer to which the backup device is connected as NDMP Servers. Add the Backup Devices Add the backup device to the NVBU Server if the device is attached to a Filer or a SmartClient. For adding devices to the NVBU Server, refer to the Quest NetVault Backup Administrator s Guide. Configure Media Block Size for Target Drives The Plug-in for SM2T v and later releases use a block size of 256K, whereas the pre releases use 240K. For ONTAP requirements, refer to the NetVault Backup Supported NAS and NDMP Compatibility Guide.

For details on adding an SM2T Server, refer to Adding a NetApp Filer to Plug-in for SM2T on page 14.

27 Quest NetVault Backup Plug-in for SnapMirror to Tape User s Guide 27 Ensure that the volume size of the destination Filer is equal to or greater than the original volume. This is necessary even if the data transferred is smaller than the overall volume size of the destination filer. For example, if the original volume was 10GB and the data snapshot from it was 2GB, relocating this data to a different volume that is only 5GB in size will result in a failure b Figure 5-5: Restore Options tab Restore Procedure To restore a volume to an alternate filer 1. Select the data to be restored. For details, refer to Selecting Data for a Restore on page Click the Restore Options tab, and configure the following parameter: NDMP Server By default, the original Filer name is displayed in this box.
