Compression levels for drive-based backups
During the creation of a
recovery point, compression results may vary, depending on the
types of files saved to the drive you are backing up.
The following table
describes the available compression levels.

Description
|
|
None
|
Use this option if storage space is not an issue. However, if
the backup is being 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)
|
This option uses low compression for a 40 percent average data
compression ratio on recovery points. This setting is the
default.
|
|
Medium
|
This option uses medium compression for a 45 precent average
data compression ratio on recovery points.
|
|
High
|
This option 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 Norton Ghost. This might improve the performance of other
resource-intensive applications that you are running at the same
time.
