Restores using Data Copy savesets fail on clients running NetVault Backup 10.0.1

Description

When restoring a Data Copy saveset on a client running NetVault Backup 10.0.1 or an earlier version, the job fails.

Symptom

The restore job reports the following error:

Failed to get index.

The trace logs contain the following messages:

New style index.

Corrupt index file, version number invalid.

Solution

On NetVault Backup Server 10.0.5 and later, the Plug-in for Data Copy creates index version 4, which is incompatible with earlier versions of NetVault Backup. A client running NetVault Backup 10.0.1 or an earlier version cannot read these index files, causing the restore job to fail.

To restore Data Copy savesets generated from NetVault Backup Server 10.0.5 or later, the client must be upgraded.

Restore fails on Itanium platforms if the index is larger than 2GB

Description

On Itanium platforms, restore fails for backups with indexes larger than 2GB in size.

Symptom

On Itanium platforms, when you try to restore a backup with an index larger than 2GB in size, the job fails with the error message “Failed when sorting items to restore.”

Solution

To correct this issue, increase the stack size:

•
On the standard UNIX platforms, edit the ulimit setting from the CLI to increase the stack size.
The following is a list of available options:
•
ulimit -a
Displays all settings for the environment.
•
ulimit -s
Displays the current stack size setting.
•
ulimit -s unlimited
Sets an unlimited stack size.
•
ulimit -s <n>
Sets stack size to the specified value.
•
man ulimit
Provides information about the ulimit command.
After changing the value, run the ulimit -a command to ensure that the setting has been changed.
•
On HP-UX Itanium platforms, use the bash command kmtune or kctune (depending on the operating system) to access to the kernel stack size information. The stack variables are maxssiz for 32-bit applications and maxssiz_64bit for 64-bit applications.
The following is a list of available options:
•
kmtune -l -q maxssiz
Displays the setting information for a 32-bit application.
•
kmtune -l -q maxssiz_64bit
Displays the setting information for a 64-bit application.
•
kmtune -u -s maxssiz=<n>
Sets the new stack size to the specified value for a 32-bit application.
•
kmtune -u -s maxssiz_64bit =<n>
Sets the new stack size to the specified value for a 64-bit application.
•
kmtune -u -s maxssiz+<n>
Increases the stack size by the specified value for a 32-bit application.
•
kmtune -u -s maxssiz_64bit +<n>
Increases the stack size by the specified value for a 64-bit application.

After upgrade, console error is displayed on WebUI pages

Description

After upgrading NetVault Backup to version 12.1, console error is displayed on various WebUI pages.

Symptom
