Introducing the Arcserve Backup NDMP NAS Option › Features

Features

The option has the following features:

Push Technology

Lets you complete a backup more efficiently by processing the data locally at the NAS server. Push technology offloads system resources from the Arcserve Backup host server and minimizes network traffic by initiating the backup and restore jobs remotely on the NAS server.

Real-time Remote Browsing

Lets system administrators view real-time file and directory information about the remote target computer.

Note: This feature requires NAS-vendor support.

Local and Three-way NDMP Backups and Restores

Lets you use a tape device attached to one of the NAS servers with the other NAS servers in the configuration. The tape device does not need to be attached locally to the NAS server to back up or restore that server.

Note: When you move NAS tape devices from one NAS server to a different NAS server, the new hardware configuration results in a three-way restore operation.

NAS Filer to Server NDMP Backups and Restores

Lets you back up the NAS filer directly to the Arcserve Backup server, where all devices that are attached to the backup server can be used as the destination of the NAS filer backup job. NAS filer to server restore jobs restore NAS data back to a NAS filer from any type of Arcserve Backup media or migrated media.

NAS Changer Support

Supports backing up and restoring NAS servers using changers or tape library units attached locally to a NAS server or remotely to a different NAS server. This feature lets you back up and restore a local or remote NAS server using a three-way NDMP backup or restore.

Multistreaming Support

Lets one agent handle different requests and perform multiple jobs simultaneously.

NAS 64-bit Support

Supports x64 Arcserve Backup servers to back up NAS filers.

Tapecopy Support

Provides the tapecopy utility, which allows you to copy NAS sessions from one tape to another.

The tapecopy utility provides the following NAS session capabilities:

• Perform a tapecopy backup of normal NAS sessions
• Perform a tapecopy backup of NAS sessions with or without a tape span situation (involving one or more tapes)
• Perform a tapecopy backup of NAS sessions from the query mode
• Perform a tapecopy backup of NAS sessions using the "-entire" source option which allows you to copy all tapes in a group to another group.

Most tapecopy switches can be used; however, some limitations apply for tapecopy support of NAS sessions:

• The tapecopy source and destination groups should be SAN dynamic device sharing (DDS) groups (accessible to both the Arcserve Backup server and the NAS filer).
• Does not support remote copy (using SAN/NAS DDS environment)
• Does not support copy to a FSD or from a FSD.
• Does not support multiplexing and encryption

Dynamic Device Sharing

Uses DDS to enable the Arcserve Backup server to share tape library units (TLU) on a storage area network (SAN). You can share a TLU between multiple NAS servers exclusively, or share multiple NAS servers with a TLU and the Arcserve Backup server. DDS enables your environment to select the optimal device to back up and restore data. For more information about DDS, see the section Dynamic Device Sharing.

Note: To use dynamic device sharing, you must install the Arcserve Backup SAN Option and Tape Library Option.
