NetVault Backup Plug-in for NDMP 11.4 - Release Notes

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.

1
In the Navigation pane, click Manage Devices, and then in the list of devices, click the applicable drive or the corresponding Manage Device icon.
2
On the Tape Drive Management page, click Check.

DNNDMP-199 (13121, NCG-289)

An issue in the ndmpversions.cfg file prevents the plug-in from allowing a rename of nlist items during a restore.

DNNDMP-668

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.

1
In the Navigation pane, click Manage Devices, and then in the list of devices, click the applicable drive or the corresponding Manage Device icon.
2
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 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 ONTAP

Backups and restores involving tape spans on NetApp 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 ONTAP

On NetApp 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 ONTAP

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

NVBU-11907 (27982)

NetApp 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 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 ONTAP

Restores with NetApp ONTAP 9.1 complete with warnings. Although the plug-in backs up the .copy_offload directory, it cannot restore it.

Workaround: Clear the .copy_offload directory from the selections to restore on the Create Selection Set page.

DNNDMP-682

NetApp ONTAP

Restoring an individual file to its original location fails if the file exists at the location. If you delete the file from the original location before performing the restore, the plug-in creates a directory of the same name as the restored file and includes the file in the directory.

Workaround: To avoid creation of the directory but restore the applicable file, use the Relocate option to select the correct location.

DNNDMP-687

NetApp 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.

DNNDMP-698

NetApp 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.

DNNDMP-699

NetApp ONTAP

If you upgrade from version 10.x or 11.1 to version 11.4 of the plug-in, the selection set created using the earlier version is not displayed correctly in the selection tree on the NetVault Backup Selections page. You must manually clear and select the correct Volumes to include in backup jobs. Use the Manage Sets option to update and save the selections.

DNNDMP-702

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.

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.
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.
