NetVault Backup Plug-in for SnapMirror to Tape 11.1 - Release Notes

Known issues

Table 2. Known issues

Restores that span tapes fail with the following error: “SMTAPE: Bad block in read stream. vbn = xxxxxxxxxx, max_vbn = xxxxxxxxx”

13506 (NTG-60)

On NetApp ONTAP 8.1.7 Mode filers, the plug-in restores data correctly, but reports the job status as failed and generates a dump.

13515 (NTG-69)

When specifying a backup path, if you omit the starting slash, the job stops responding.


On Clustered Data ONTAP 8.3, backups are performed using TCP connections instead of local connections because the plug-in fails to get affinity information about volumes and tape devices on this OS.


When performing a SnapMirror to Tape backup job, if you kill the NDMP sessions, the job stops responding.


Currently, BLI backups are not supported on Clustered Data ONTAP 8.3.


On NetApp filers running ONTAP 7.0 and later, if you try to restore data from a Traditional Volume to a Flexible Volume, the job fails.


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.

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.
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.
