Running system compression
If you have configured a backup with no compression type in the DS-Client, you can run system compression on the backup to compress 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, you must enable DS-Client encryption key management and you must forward the DS-Client encryption key(s) to the DS-System. For more information, see
“Configuring the encryption key settings”.
To run system compression:
1. Under the Customers tab, right-click the backup for which you want to run system compression, and then click Run System Compression.
2. In the Additional validation threads box, enter the number of additional threads you want to use for the compression process.
3. If the DS-System is running in an N+1 configuration, in the N+1 ID to perform activity box, select the DS-System on which you want to run the compression process.
4. In the Additional validation threads box, enter the number of additional threads you want to use for the compression process.
5. Click OK. You can verify the system compression results in the Activity Log.
