Logical Block Protection (LBP) is functionality offered by manufacturers of stand-alone tape drives, such as IBM and HP, that lets Arcserve Backup detect read and write errors that occur on drives under the following conditions:
When an error occurs, the drive reports a SCSI error in the Tape Engine log file and the backup will fail.
The Arcserve Backup implementation of LBP does not support the following backups:
Example: Data deduplication and staging backups
To implement LBP, you can create the registry key described in the following procedure. The registry entry can be created under the DEVICE<#> key in the registry for the stand-alone tape drive.
Follow these steps:
HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\CA ARCServe Backup\Base\TapeEngine\DEVICE<#>
Note: DEVICE# represents the number of the device where you want to implement LBP.
LBP
Note: To disable LBP, set the DWORD value of LBP to 0.
