NetVault Plug-in for SnapMirror to Tape 11.1

To perform backups to a virtual tape library, you must set the Device Block Size to 256K. For instructions configuring this setting, see the topic on Managing Storage Devices in the Quest NetVault Backup Administrator’s Guide.

The backup option Delete Snapshot on Exit (SMTAPE_DELETE_SNAPSHOT) is only supported on ONTAP versions 6.5 P5 and later, 6.5 H2 and later, and 6.5 R2 and later.

If a filer reboots or there is a loss of network connectivity with the filer while the plug-in is running, the filer-attached drive goes offline with the message “Command Failed, Re-initializing Driver” when the plug-in tries to access the drive after the NAS Device is brought back online. After a few minutes, the drive recovers and becomes online, but you must perform a manual check before using the drive.

To perform a manual check

In the Navigation pane, click Manage Devices, and then in the list of devices, click the applicable drive or the corresponding Manage Device icon.

On the Tape Drive Management page, click Check.

If you had issued any load or unload requests before performing this procedure, try them again after the check.

When a job starts child jobs, the user logged in to NetVault Backup when creating the parent job remains the owner of the parent job, but the child jobs are owned by the default user. This issue can affect NetVault Backup Reports, Job Status page, and other functionality that depend on job ownership.

Upgrade and compatibility

•

Select the correct installation package on Linux and Windows: NetVault Backup offers separate client‑only and server-only installation packages for Linux- and Windows-based systems. Both the server and the client packages are available in hybrid and pure 64-bit versions:

•

Hybrid server and client packages: The hybrid packages are intended for users who do not have a pure 64-bit-only requirement.

These packages let you upgrade from pure 32-bit and hybrid installations of NetVault Backup. The hybrid packages retain binary compatibility with all previous versions of 32-bit and 64-bit plug-ins. These packages also work on 32-bit systems that do not have 64-bit capability.

•

Pure 64-bit server and client packages: The pure 64-bit packages are intended for pure 64-bit operating systems. If you have a specific reason that you cannot use any 32-bit components (for example, you are using a Linux distribution that does not run 32-bit code), use these packages.

The pure 64-bit packages cannot be used to upgrade existing pure 32-bit or hybrid NetVault Backup installations. You must remove the existing pure 32-bit or hybrid version and install the pure 64-bit version separately. To reduce confusion, warning messages have been added to both the upgrade and installation packages to ensure that you understand that they are incompatible.

Depending on your OS type, make sure that you select the correct installation package to install the NetVault Backup Server software:

•

netvault-<RYYYYMMMDD>-vx.x.x.x-Server-{LinuxX86Hybrid|WindowsX86Hybrid}: Use this package to install or upgrade NetVault Backup Server on 32-bit or 64-bit systems.

•

netvault-<RYYYYMMMDD>-vx.x.x.x-Server-{LinuxX86Pure64|WindowsX86Pure64}: Use this package to install or upgrade NetVault Backup Server on pure 64-bit systems.

For client installations, make sure that you select the appropriate package based on your system.
