Known issues

In NetVault Backup WebUI, while editing a restore selection set, on Edit Selection Set page, the Next button is disabled.

Workaround: Select or clear the data selection tree check box on Edit Selection Set page.

NVBU-16148

Sometimes the diagnostic data for few NetVault Backup client machines with old configuration is partially collected due to timeout.

Workaround: Increase the value in the field ‘Physical Client Long Timeout’ in the Web Service timeout settings from NetVault Backup WebUI.

NVBU-15735

Quest DR Device is not accessible after you change the DR Device user password.

NVBU-15843

CLI displaying non English characters incorrectly. For example,

NVBU-13974 (31104), NVBU-13736 (30702)

The restore job from NDMP backup data copied to 256Kib drive fails and displays error message 'NDMP data does not start on a block boundary'.

Workaround: https://support.quest.com/netvault-backup/kb/212701

DNNDMP-657 (31825)

NetVault Backup is unable to send the report as an email attachment in PDF format on RHEL 5.x platform.

Workaround: To send the report as an email attachment in HTML format, follow these steps:

2
On the Configuration page, click Server Settings.
3
Under ‘User Interface’, click Reporting. In the Reporting dialog box, under ‘Misc’, configure the following setting:
Default mail format: Select HTML.
4
Click Apply to apply the new settings and close the dialog box.

NVBU-14529 (31878)

On Manage Devices page, in Tree View, clicking “Scan” option directly starts scanning the selected slot/drive/library. It does not show the dialog box for “Minimum life for imported backups (days)” and a confirmation message.

NVBU-14745 (32197)

On Manage Devices page, in Tree View, you cannot select multiple media from the list of available media for bulk blank operation.

NVBU-14758 (32214)

On Manage Devices page, in Tree View, you cannot select multiple media from the list of available media for bulk label operation.

NVBU-14759 (32215)

When performing backups with the NetVault Backup Plug-in for Teradata, if the number of parallel streams exceeds the SoftStreamLimit set for the target NetVault SmartDisk, the backup job stops responding.

NVBU-389 (1948)

When a backup that is configured as “restartable” is duplicated, only the data backed up in the last restarted instance of the job is duplicated.

NVBU-1160 (3971, (NVG‑4022)

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.

NVBU-1186 (3997) (NVG‑4206)

On Linux- and UNIX-based systems, the progress message that is displayed during NetVault Backup installation are displayed correctly only if the system is configured to use UTF-8 character set.

NVBU-10588 (26249)

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.

NVBU-11005 (26778)

Starting with NetVault Backup 10.0.1, the built-in plug-ins use four-digit version numbers (for example, 10.1.1.1).

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.

NVBU-10927 (26687)

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.

1
Open the file “drives.tpl” in a text editor. You can find this file in <NetVault Backup home>\devices\drives on Windows and <NetVault Backup home>/devices/drives on Linux and UNIX.
2
In the [Device:Total Buffer Size] section, set Value to 257.
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.

NVBU-11305 (27165)

On Windows 2012, the Plug-in for Databases fails to restore a NetVault Database backup that is stored in a NetVault SmartDisk device.

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.

NVBU-11307 (27167)

After upgrading to Firefox 31, if you try to log in to the NetVault Backup WebUI, the following error message is displayed:

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:

2
Locate the preference security.use_mozillapkix_verification, and set it to false.

NVBU-11321 (27189)

When many backup jobs that target the same disk-based storage device are scheduled to start at the same time or within a small window of time, the following issues occur:

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.

1
Open the mediamgr.cfg file in a text editor. You can find this file in <NetVault Backup home>\config on Windows and <NetVault Backup home>/config on Linux.

Note the following:

NVBU-12089 (28204)

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.

NVBU-12734 (29149)

If a deployment task is stopped (or the Deployment Manager or NetVault Backup Service shuts down) while a task is still running, the task status is set to “Complete” and the individual targets are marked as “Completed with Errors” even if the software packages are successfully installed on the target machine.

NVBU-13433 (30274)

The shared directory path for push installations cannot contain non-English characters.

NVBU-13564 (30451)

Under certain conditions, the NetVault Backup Server may be unable to determine the status of the push installation task on a remote client. In such cases, the task status may remain in the “Running” state. This error can occur under the following conditions:

Subsequent tasks remain in a “Pending” state until you cancel the previous task.

NVBU-13610 (30508)

When performing push installations, if you use any illegal characters in the machine password for a new client, the remote installer reports an error and fails to install the software on the client.

NVBU-13632 (30537)

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).

NVBU-13647 (30558)

Known issues related to Plug-in for RDA on Solaris:

Backing up file system data from Solaris clients to DR Series Systems: When you perform file system backups to DR Series systems, the backups run in the Passthrough mode by default. You can change the default setting on the DR Series system to run backups in the Dedupe mode, but you may experience slow backup performance in this mode.
Restoring data from a DR Series System to a Solaris Client: When you run multiple restore jobs at the same time, it can affect the performance of individual jobs and result in low aggregate throughput.

NVBU-13678 (30596)

Known issues related to DR Series Systems:

When performing a backup using the NetVault Backup Plug-in for VMware (Plug-in for VMware), if you set the client mode type to dedupe, the throughput is lower when compared with the passthrough mode. If you do not set the client mode on the DR Series system, the Plug-in for RDA automatically chooses the best mode for the backup.

 

On a Linux system, NetVault Backup fails to access a DR Series system if you do the following:

When you remove the 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 plug-in, complete the following steps:

1
Ensure that the /usr/local/oca-libs directory has been removed. If not, remove the directory.

 

The Delete Non-Scheduled Jobs option is intended to delete non-scheduled jobs after a specified period. Since the jobs using the Triggered schedule type have no physical scheduled time, they are also deleted after the specified period elapses. If you are using Triggered jobs in your NetVault Backup environment, do not use the Delete Non-Scheduled Jobs setting.

 

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 Backup 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.

 

After restoring the NetVault Database, when you restart the NetVault Backup Service, the job status shows “Scheduler Aborted Whilst Job Running.” This message can be ignored.

 

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 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. For more information, see https://support.quest.com/kb/SOL79286.

 

If the default locale is changed (for example, from UTF8 to EUC or from EUC to UTF8), the EULA may not be displayed properly.

Workaround: To view the EULA, use a terminal that can display EUC character set.

 

Job details are not displayed when you click a policy job in Job Status widget on NetVault Backup Dashboard page.

NVBU-17538

After running a job, when you go to Job Status page to monitor the status of the job, it shows all the jobs with previously applied filters instead of showing all current activity.

Workaround: Select the option ‘Current Activity’ in the ‘View By’ job status filter option.

NVBU-17582

Unable to restore the data items using catalog search from network share backup.

NVBU-17632

Edit option on Set Management page allows to select multiple backup sets while editing an existing set for a Data Copy backup job.

NVBU-14441 (31745)

When a job that is set to Priority 1 goes into a Waiting for Media state, all subsequent Phase 2 (Secondary Copy) jobs also go into a Waiting for Media state.

Workaround: To ensure that all Phase 2 jobs continue instead of going into a Waiting for Media state, reduce the priority level of the initial job. This change ensures that multiple requests that target the same media can continue even if one request is in a Waiting for Media state.

NVBU-17795, NVBU-18025

QoreStor does not support multi-tenancy.

QS-437, DNR3-71

Solaris backup jobs that target QoreStor or a DR Series system are not supported.

QS-1824

If you are upgrading from a previous version of NetVault Backup, verify that none of the existing NetVault Backup users have an @ symbol in their User Name. Update the User Name for any users whose name does contain an @ symbol. NetVault Backup assumes that a name that contains @ is a domain user and automatically tries to authenticate it with AD when the user logs on. If an existing user tries to log on and NetVault Backup is unable to authenticate the user with AD because the credentials do not match, login fails.

DNAD-523, DNAD-562

When the Broadcast details to machines on local networks setting is disabled on a client, the nvclient utility fails to add the client.

Workaround: Use the nvclientadd -clientip <Client IP address> command to add the client.

NVBU-12966 (28829)

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 Backup WebUI.

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 Unload.
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.

 

Table 7. Plug-in for FileSystem known issues

On Snap Appliance Filers, data must only be relocated to existing directories. Items relocated to directories that do not exist cannot be accessed due to permissions settings on the newly created directories.

DNFSP-113 (13979, (FSG‑188)

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.

DNFSP-456 (14324, (FSG‑514)

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.

DNFSP-508 (14376, FSG‑563)

On Solaris ZFS and UFS file systems, the files and directories for which only the extended attributes have changed do not qualify for Incremental Backups.

DNFSP-636 (14504, FSG‑684)

When restoring a Linux or UNIX backup to a Windows-based NetVault Backup Client, the items are restored successfully, but the job generates the following warning and log context:

Log message: <num> items and their contents could not be restored

Log context: <filename>: writing to file: Incorrect function

These messages can be ignored.

DNFSP-718 (14586, FSG‑760)

On Windows 2008 and Windows 2003, the System State node does not include the Removable Storage Manager Database node.

 

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:

 

Although VSS backups complete successfully, the message “Error deleting volume snapshot(s): VSS_E_BAD_STATE” is written to the NetVault Backup logs.

 

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.

 

When a symlink is restored, GuardianOS applies the Xattr attribute user.SnACL to it. This behavior is expected and does not have any negative effects.

 

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:

[Performance:DoRecursiveAutoMountScan]

Value=FALSE

 

The nvreport utility does not work in the MSP environment.
