How fast will my restores be? To determine restore performance, you must measure how fast data can be read reads from tape and how fast data can be written to disk. Restore performance will be the slower of these two measurements. • Use the Device Performance test to measure the speed of the tape drive. • Use the System Performance Restore Pre-test to measure the speed of the disk subsystem. Note this test is independent of the backup application and uses test restore data. Please check with your backup vendor if actual backup performance is significantly slower.

How fast will my restores be?
To determine restore performance, you must measure how fast data can be
read reads from tape and how fast data can be written to disk. Restore
performance will be the slower of these two measurements.
•
Use the
Device Performance test
to measure the speed of the tape
drive.
•
Use the
System Performance Restore Pre-test
to measure the
speed of the disk subsystem.
Note this test is independent of the backup application and uses test restore
data. Please check with your backup vendor if actual backup performance is
significantly slower.
