Running system compression
If a backup set has been configured in DS-Client with no compression type, you can run system compression on the backup set to compress any uncompressed data in the DS-System online storage. The DS-System uses ZLIB for the compression type and only compresses files larger than 32 KB.
NOTE: To run system compression on a backup set, DS-Client encryption key management must be enabled and the DS-Client encryption key(s) must be forwarded to the DS-System. For more information, see
“Configuring the encryption keys settings”.
To run system compression:
1. In the Customers tab, browse and select the backup set on which you want to run system compression.
2. Right-click the backup set and select Run System Compression. The System Compression dialog box appears.
Select the options for the compression.
3. Click OK.
You can verify the system compression results in the activity log.
