Compression level options

The following table describes the compression levels that you can apply to the recovery points.

See Scheduling a backup.

Table: Compression level options

Option

Description

None

Indicates that no compression is applied to the recovery point. Use this option if storage space is not an issue. However, 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.

Standard (recommended)

Uses low compression for a 40 percent average data compression ratio on recovery points.

This option is set by default.

Medium

Uses medium compression for a 45 percent average data compression ratio on recovery points.

High

Uses high compression for a 50 percent average data compression ratio on recovery points. This option 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 slow down.
