Variables currently undocumented
Treewalk
A treewalk is performed when backing up a file system to calculate how many files have changed
since the last full backup.
NOTREEWALK=1 is the correct variable for Data Protector 6.0. It works exactly the same in the
Data Protector 6.1 code, only the syntax is different. It is undocumented in the the Data Protector
6.0
omnirc file.
• Data Protector 6.0:
o if (EnvGetBool(_T("NoTreeWalk"))) opt.firstTreeWalk=0; /* old
variable still checked */
• Data Protector 6.1:
o if (EnvGetBool(_T("OB2NOTREEWALK"))) opt.firstTreeWalk=0; /* new
variable */
Note: If you abort a backup session while it is still determining the sizes of the disks that you
have selected for the backup, it does not abort immediately. The backup is aborted once the size
determination (treewalk) is completed.
Note: Windows and Unix treewalks are run differently. See the HP Data Protector Performance
White Paper (4AA1-3836ENW) for further details.
Event management
Setting up SNMP trap forwarding
To set up SNMP event forwarding, follow the basic configuration steps as described in the Data
Protector online help.
To configure SNMP trap forwarding from the HP Data Protector Cell Manager to any trap-
receiving recipient, follow the following steps:
1. Run
omnisnmp.exe command from the <Data_Protector_home>\bin directory. It will
create the appropriate Data Protector entry in the System registry under
CurrentControlSet\Services\SNMP\Parameters\ExtensionAgents.
2. In the Control Panel, select Network and Dial-up Connections (Windows 2000) or
Network Connections (Windows XP/Server 2003).
3. In the Advanced menu, select Optional Networking Components to start the wizard.
4. Select Management and Monitoring tools and click Next.
5. Follow the wizard to install the management and monitoring tools.
