Compression level options (continued)
DescriptionOption
Uses medium compression for a 45 percent average data
compression ratio on recovery points.
Medium
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 Symantec System Recovery. This might
improve the performance of other resource-intensive
applications that you are running at the same time.

Running a one-time backup from Symantec System
Recovery
You can use One Time Backup to quickly define and run a backup that creates an
independent recovery point. You use the One Time Backup wizard to define the
backup. The backup runs when you complete the wizard. The backup definition
is not saved for future use. You can use the independent recovery point later.
This feature is useful when you need to back up your computer or a particular
drive quickly before a significant event. For example, you can run a one-time
backup before you install new software. Or, you can run it when you learn about
a new computer security threat.
You can also use Symantec System Recovery Disk to create one-time cold backups.
