Compression levels for recovery points
During the creation or copying of a recovery point, compression results may vary, depending on the types of files that are saved to the drive you are backing up.
The following table describes the available compression levels.
Table: Compression level options
Option | Description |
---|---|
Indicates that no compression is applied to the recover point. Use this option if storage space is not an issue. If the backup is saved to a busy network drive, high compression may be faster than no compression because there is less data to write across the network. | |
Uses low compression for a 40 percent average data compression ratio on recovery points. This setting is the default. | |
Uses medium compression for a 45 percent average data compression ratio on recovery points. | |
Uses high compression for a 50 percent average data compression ratio on recovery points. This setting is usually the slowest method. When a high compression recovery point is created, CPU usage might be higher than normal. Other processes on the computer might also be slower. To compensate, you can adjust the operation speed of Veritas System Recovery. Adjusting the speed may improve the performance of other resource-intensive applications that you are running at the same time. |
