View Compression Results after Deduplication

You can view the compression ratios achieved after a backup job with deduplication is completed in the Activity Log. Compression is displayed as a ratio and as a percentage. This information is also stored in the CA ARCserve Backup database, so you may view it in Job History at the session level, job level and node level.

• From the Restore Manager, you can view session level compression ratio information.
• From the Backup, Restore or Device Managers, you can view the device/tape level compression ratios.
• From the Report Manager, you can view the session compression ratio from the Session Details and Session Reports. You can view device level or node level compression ratio from the Dashboard report.

The compression ratio is the result of the amount of actual data to be stored divided by the amount of data stored after deduplication expressed as a ratio or as a percentage.
