When performing backups with the NetVault Backup Plug-in for Teradata (Plug-in for Teradata), if the number of parallel streams exceeds the SoftStreamLimit set for the target NetVault SmartDisk, the backup job stops responding. |
|||||||||
|
In NetVault Backup with non-English locale, Running Status field did not display a current job status as the output of nvreport command and Report Job. |
|||||||||
|
If the Network Manager process (nvnmgr) stops responding due to any error and fails to exit properly, it prevents the NetVault Backup Service from starting on that machine. When this error occurs, manually kill or end the nvnmgr process before restarting the NetVault Backup Service. |
|||||||||
|
If you install the built-in plug-ins available with 10.0.1 and later on a machine running NetVault Backup 10.0, the About dialog box displays the correct 4-digit version number, but the other WebUI pages (for example, the Manage Clients page) display 3-digit version numbers with incorrect release numbers (for example, it may display 10.0.257 instead of 10.0.1). Similarly, if you install a plug-in that uses the old version format on NetVault Backup 10.0.1 and later, the About dialog box displays the correct version number (for example, 2.6.5), but the other WebUI pages display incorrect release and build numbers (for example, 2.6.0.5). In such cases, use the About dialog box to determine the correct version number of a built-in plug-in. |

|
The Drive Transfer Buffer Size option is now set to 8 MiB by default. To ensure that this configuration is supported on your system, verify your OS settings before adding a tape device. If this value is too high, change it to 257 KiB in the template file.
NOTE: If Drive Transfer Buffer Size is set too high and NetVault Backup fails to allocate the transfer buffers, the backup jobs using tape devices show reduced performance. |
|||||||||
|
Workaround: If the NetVault Database backup is stored in NetVault SmartDisk, stop the NetVault Backup Service and run the service in “user space” (that is, nvpmgr debug) before starting the restore job. |
|||||||||
|
Issuer certificate is invalid. (Error code: sec_error_ca_cert_invalid) The new security library security.use_mozillapkix_verification raises this certification error when you try to access a self-signed certificate. Workaround: To resolve this issue, do the following:
|
|||||||||
|
These issues occur because the Media Manager uses a “quiesce time” setting to prevent assigning too many simultaneous jobs to a disk-based backup device. By default, the quiesce time is set to 10 seconds. Thus, after a job is assigned to a disk-based storage device, the Media Manager waits for 10 seconds before assigning the next job to the same device. You can change the default setting for quiesce time in the mediamgr.cfg file.
|
|||||||||
|
On Windows, if a copy of “.cfg” file is created in the <NetVault Backup home>/config directory, the WebUI may display empty or partly empty dialog boxes when the settings are accessed from the Change Settings page after restarting the service. |
|||||||||
|
The shared directory path for push installations cannot contain non-English characters. |

|
If the server IP address is used to configure a local package store (for example, \\10.11.12.3\PkgStore), the user credentials are not validated when the package store is added or updated. If you specify invalid credentials, no errors are reported. However, the deployment task fails if the authentication fails and the packages cannot be retrieved from the store. Therefore, Quest recommends that you use the server name when configuring the path to a local store (for example, \\WinServer1\PkgStore). |

|
|||||||||
|
On a Linux system, NetVault Backup fails to access a DR Series system if you do the following: When you remove the RDA plug-in, it deletes the directory /usr/local/oca-libs, which causes an error when NetVault Backup tries to access the device. Workaround: After removing the RDA plug-in, complete the following steps:
|

|
When using NetVault Backup Plug-in for NDMP (Plug-in for NDMP), if you run multiple jobs with the auto-deletion option set to “On,” the parent and child jobs may still be listed on the Job Status page. To correct this issue, close the NetVault WebUI, and start it again. There is no need to stop and restart the NetVault Backup Service. |
|||||||||
|
The canned report “Disk Storage Devices — General” is intended for the NetVault SmartDisk devices; this report does not show details about the DR Series systems and Data Domain Systems. |
|||||||||
|
On a Solaris (SPARC or x86-64) system, when the LANG variable is set to en_US.UTF-8, the restore job wizard does not display the filenames on the Create Selection Set page. This issue is not encountered when LANG is set to C. |
|||||||||
|
On Windows Vista, Windows 2008, and Windows 7, if the OS firewalls are turned on, connectivity issues between the NetVault Backup Client and Server may be encountered occasionally even if the port exceptions have been correctly configured on the NetVault Backup Client.

|||||
|
The asf_load_media command fails if the machine name contains any spaces. |
|||||
|
When the asf_release_drive command is issued to various brands of library devices (for example, those containing various Exabyte or 9840 drives), a delay of up to eight (8) minutes may occur before a piece of media is unloaded. Workaround: The workaround is to issue the “Unload” command from the NetVault WebUI.
The drive remains in and “Idle” state, and media are not unloaded as expected. If the logs for the selected device are viewed, an entry stating “Unload media in drive <X> failed — Device unavailable” is displayed. Repeat Step 2 to unload the media. |
|||||
|
The range function does not work properly for the nvacslsmedia command. Workaround: The workaround is to explicitly run this command for each media item that you want to allocate or deallocate. You can use a script to do this task. |
|||||
|
When a space character is all that is specified for a library name with the nvcleandrive command, the first library on the Manage Devices page performs a clean operation on the specified drive. For example, if you run the command nvcleandrive libraryname “<space character only>” -librarydrivenumber <X>, NetVault Backup automatically targets the first library on the Manage Devices page and perform a clean operation on drive <X>. |
|||||
|
When a null value is specified with the nvexpiresaveset command, any random saveset is expired. |
|||||
|
When you run the nvjobmodify command, the job is submitted to run, even if you do not include the “‑submit” option in the syntax. |
|||||
|
When a null string is specified with the nvremovemedia command, the first entry is deleted from the Media Database. |
|||||
|
The nvsetcleaninglives command does not report any errors if you configure incorrect values for the lives option. |
|||||
|
The “-include” option for nvsetcreate cannot be used to specify data selections below the “Fixed Drives” node in the selection tree. |
|||||
|
The nvsetmodify command cannot be used to modify Schedule Sets. You can create a set using nvsetcreate, and assign it the same name to overwrite the existing set. |
|||||
|
On Windows-based installations, the nvsyncronizesilomedia command does not update the media status on the Manage Devices page. |
|
On ZFS, if the backup data contains ACLs on extended attributes, the restore job fails when you use the default restore options. If errors occur on restore of metadata, select the Discard Metadata option to restore the data. |
|
|
The IIS Metabase node in the System State tree is not visible by default on Windows Vista, Windows 7, and Windows 2008 systems. To enable this node, install the ISS 6 compatibility pack, or create a selection set that includes the IIS config and schema files located under %windir%\system32\inetsrv\config. |

|
The Verify After Backup option does not work for a restarted job instance. |
|
|
When you submit a policy job created for a UNIX file system on a Windows system, the job status shows “Completed with Warnings,” but no data is backed up. |
|
|
The following known issues apply to the Backup Windows File Short Names and Restore Windows File Short Names options: |
|
|
If a job restores a Windows symbolic link (file created using mklink, not Windows shortcut), where the symbolic link file exists on the target file system and the data file the symbolic link targets also exists, the data in the targeted data file is lost. Ensure that the data files targeted by symbolic links are included in backups. Quest recommends that you delete the existing symbolic links that you want to restore from the target file system before running a restore job. To avoid any risks of data loss, you can also perform backup of data files possibly at risk before running the restore job. |
|
|
Backups on GFS and GFS2 can stop responding if the files or directories are frozen. |
|
|
In an environment with many direct automounts on Solaris Clients, a backup job may remain at “Waiting for Job Options” status while the Plug-in for FileSystem attempts to load the automounts temporarily to determine whether they are on remote systems. This delay can be alleviated by selecting the “Backup through Remote Mounts” option. If necessary, clear or exclude remote mounts or add the following stanza to the file nvfs.cfg: |

Upgrade and compatibility
|
• |
NetVault Backup Server OS requirements: Starting with 10.0, the NetVault Backup Server installation is only supported on Windows and Linux operating systems; the server installation is no longer supported on UNIX and Mac OS X operating systems. |
|
• |
NetVault Database migration: Upgrade from 9.2 involves the migration of NetVault Database from proprietary format to the PostgreSQL database. The migration can take a significant amount of time depending on the size of your NetVault Database and other factors such as system performance. |
|
NOTE: Before upgrading from NetVault Backup 9.2, purging unnecessary logs can significantly reduce the database migration time. For more information about purging log files, see the Quest NetVault Backup Administrator's Guide. |
|
IMPORTANT: Before upgrading from 9.2, verify that you create a backup of the NetVault Database. The database format introduced in 10.0 increases the importance of performing NetVault Database backups before upgrading from 9.2. For more information about backing up the NetVault Database with the Plug-in for Databases, see Quest NetVault Backup Built-in Plug-ins User’s Guide. |

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. |
|
IMPORTANT: Before installing the hybrid package of NetVault Backup on 64-bit Linux machines, ensure that all the required 32-bit libraries are installed on the system. For more information about the requirements, see the Quest NetVault Backup Installation Guide. The installation process may fail silently if the installer is unable to find the required libraries on the system. |
|
NOTE: X = Compatible |
|
• |
Licensed plug-ins: After upgrading to the latest version of NetVault Backup, you may be unable to create new backup jobs with previously installed licensed plug-ins. This issue occurs in the following upgrade scenarios: |
|
• |
SNMP Trap Notification Object Identifier (OID): After you upgrade from NetVault Backup 9.2, the OID for the SNMP Trap Notification method is changed. |
|
• |
NetVault Backup Plug-in for NetWare (Plug-in for NetWare): NetVault Backup 10.0 and later do not support Plug-in for NetWare. |
|
• |
Plug-in for VMware and NetVault Backup Plug-in for Hyper-V (Plug-in for Hyper-V): After installing the Plug‑in for VMware or Plug-in for Hyper-V, if you upgrade the NetVault Backup software, you must re‑install the plug-in on that machine. If you do not reinstall the plug-ins, you cannot open the Drives node of a mounted virtual machine to create any new file‑level backup jobs. |
|
• |
Device names containing multibyte characters: After upgrading from NetVault Backup Server 9.2, a device that uses multibyte characters in its name must be removed and added again. |
