About the DSL Data Utility

If the disk space is full and data should be retained, then use Storage Extension feature

DSL Data Utility is used to increase Dedupe Storage Location (DSL) space without impacting user’s backups and restores

Moves DSL data from the configured DSL to another storage location

Any new backups created after the DSL data movement will be backed up to the user's original DSL

Data in the moved dedupe chunk will be restored (restores run from the Target DSL)

Using the DSL Data Utility

1. Disable all clients to temporarily stop all read and write operations
2. Create a new DSL to which data will be moved
   • From DLO Admin Console under Configured Dedupe server > Manage Dedupe server > DSL
   • Target DSL must in the same pool as the source DSL
3. Edit the DDRedistribute.ini file, by default in C:\Veritas\Veritas DLO
4. Run the RedistributeDSLData.exe file, by default in C:\Veritas\Veritas DLO
5. Enable all clients

Editing the DDRedistribute.ini

DDRedistribute.ini parameters:

HTTP_SERVER = Machine IP and port for DedupeServer

HTTPS_SERVER = Machine IP and port for DedupeServer

SOURCE_DSL= Source DSL for the data chunk to be copied

TARGET_DSL=Target DSL for the data chunk to be moved

AUTO_DELETE = If set TRUE, it will delete the chunk from Source once copied to Target

MOVE_ALL = FALSE, moves the data as specified in the MIN_USER_DATASIZE

SPACE_TO_RECLAIM = Size should be equal to or more w.r.t. the chunk data (in MBs)

MAINTENANCE_TIMEOUT = Time (in minutes) for which the Dedupe server has to be in maintenance mode. Default value set to 200.

MIN_USER_DATASIZE = Threshold size for chunk data (in MBs)
