The following options are available for the Restore Performance Test:
•
Filesize —Specify the size, in bytes, of the test files to be created.
•
Number of Files —Specify the number of files to be created.
•
Directory path —Specify the path of the directory where the test files will be written.
This must be a directory on the backup server being tested. Make sure that the path is
on the restore destination disk to measure the real data rate. Use a directory name that
you can find easily such as C:\Test so that you can easily delete the data later.
•
Pattern —Specify one of the following data patterns:
◦ Fixed byte
◦ Incrementing byte
◦ Random data
◦ 1.6:1 compressible data
◦ 2:1 compressible data (suggested starting value)
◦ 3.1:1 compressible data
◦ 4.3:1 compressible data
4. Use the start command to start the test.
