NetVault Plug-in for NDMP 12.2 - Release Notes

Resolved issues

Corrected an issue that caused a search for a file in a restored saveset to display two paths — one correct and one incorrect.


Corrected an issue with Data ONTAP 9.x that caused a restore job to complete with warnings.


Corrected an issue that caused the restore of an individual file to its original location to fail if the file existed at the location. Also corrected the issue that caused creation of a directory with the same name as the restored file.


Corrected an issue with Data ONTAP 9.x that included all subvolumes in a backup even if you selected a main volume for a backup job and excluded any Vserver or subvolumes.


Corrected an issue in which selecting the Backup Subvolumes Individually option caused backup jobs to fail with Data ONTAP operating in 7-Mode.


Known issues

The filenames containing characters from the extended character set are not displayed correctly in the restore selection tree.

DNNDMP-115 (13037, NCG‑203)

If the NetVault Backup Service is stopped when the status of a restartable NDMP backup job is “Waiting to Retry Backup,” the drives in use by that job become offline.

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.

DNNDMP-199 (13121, NCG‑289)

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


The history component of a dump, which tracks the various levels of dumps in the series, is transferred as the last item in a dump backup. This component increases the time taken to generate the backup index; it also increases the processor and memory usage for a job.


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.


Dell FluidFS

If you use more than 32 entries in the EXCLUDE option for a backup job that targets a Dell FluidFS, FluidFS does not return an error. Exceeding the same limit using the EXCLUDE_PATH option works correctly.

DNNDMP-661 (32079, 00040990)

EMC Celerra

If an EMC Celerra reboots or there is a network connectivity loss with the device while a job is in progress, the plug-in does not automatically cancel the job. You must manually cancel the job.


EMC Celerra

After adding the first filer-attached device, a delay of up to 30 minutes may occur when you try to add the other devices attached to the EMC Celerra. The delay occurs when NetVault Backup attempts to scan the device for addition.


EMC Celerra

Selective restores with Plug-in for FileSystem using EMC Celerra attached tape device is not supported.

NVBU-47 (773)

Hitachi BlueArc

Due to a fault in the Data Copy Plug-in, restores with Duplicate or Data Copy savesets fail for the Hitachi BlueArc. This failure is only encountered on Windows platform. Moreover, only a particular configuration causes this problem. It only occurs when the original savesets are generated using drives local to the NetVault Backup Server, while the Duplicate or Data Copy savesets are generated using drives that are local to the filer.


Hitachi BlueArc

Hitachi Essential NAS does not support Direct Access Restore (DAR).


Hitachi BlueArc

Hitachi Essential NAS does not support Rename and Relocate options.

DNNDMP-352 (13274, NCG‑442)

Hitachi Essential NAS

Hitachi Essential NAS only supports backups and restores to NetVault Backup Server or Client attached backup devices.


Isilon OneFS

Isilon OneFS 4.7.2.x does not support child-level data selection for restore. This limitation is imposed by a syntax handling error. Restore job on OneFS 4.7.4.x requires you to select data at the parent-level


NetApp Data ONTAP

Backups and restores involving tape spans on Data ONTAP GX filers may display the error message “Tape Reading Operation Terminated.” This error is expected. Despite this error message, the backup or restore job preserves data integrity.


NetApp Data ONTAP

On Data ONTAP 7.1, you may encounter errors during Direct Access Restores. You must upgrade to ONTAP 7.1.1 or a later version to resolve this issue.


NetApp Data ONTAP

Restores of selective files from filer-attached devices fail with the error “tape read error.”

NVBU-11907 (27982)

NetApp Data ONTAP

If a device hosted on a different node is specified for a backup or restore job, the plug-in performs an affinity match and uses a local device instead of using the specified shared device.

NVBU-12310 (28510)

NetApp Data ONTAP

If a device failure occurs during an NDMP backup or restore operation, the job does not fail; it has to be canceled manually.

NVBU-12506 (28798)

NetApp Data ONTAP

If you are using Plug‑in for NDMP or Plug-in for SnapMirror to Tape with Data ONTAP 9.1 and you perform multiple-volume backups, the job might fail and display a “Mover has halted due to an internal error” message.


NetApp Data ONTAP

Installing the plug-in on the client prevents you from clicking the Volumes node to select all Vservers, volumes, directories, and files automatically on the NetVault Backup Selections page, nor can you select multiple items manually. You can only select one item to back up.

Workaround: Install the plug-in on the server instead of the client, or create a separate backup job for each item that you want to back up.


NetApp Data ONTAP

The plug-in fails to restore a file or directory to a different Vserver in a locally attached — direct — topology. Restoring a file or directory to a different Vserver works in remote — indirect — and 3-way topologies.


NetApp Data ONTAP

If you use the Incremental forever feature, the plug-in runs a Full Backup twice before starting the Incremental Backup process. The second Full Backup is not full. The pattern repeats so that every Full Backup is followed by a nearly Full Backup and subsequent Incremental Backups.


Sun StorageTek 5320

On a Sun StorageTek 5320 filer running OS 4.20 M3 Build 1, the plug-in may erroneously mark a used media as bad after attempting to read the header. This error occurs when you try to blank media from the GUI or CLI. To avoid this problem, upgrade to OS 4.21 or later.
