Verifying a Backup

8 Verifying a Backup

Nero BackItUp can be used to verify an existing backup. Nero BackItUp verifies whether or

not the backup

can be used for a successful restore process. During this process, data integ-

rity is checked, and the backed up data is compared to the source data. If you carry out the

verification right after the backup and have not modified any data in the meantime, you can

use the feature to verify whether or not all data was backed up successfully (data verifica-

tion).

To verify the backup, proceed as follows:

1. Click the Wizards menu icon.

 The Wizards screen appears.

2. Click the Verify Backup button.

 The Verify Wizard window opens and the welcome screen appears.

3. Click the Next button.

4. The Verify Settings screen appears.

5. Click the button.

 The Open Backup window opens.

6. Select a backup from the selection list or select a different backup using the option buttons

and the

button.

7. Click the OK button.

 The Open Backup window closes. The selected backup is transferred and the name of

the backup is shown in the Select Backup display panel. The Select any option to ver-

ify the backup area is available.

8. If you selected a file backup, specify the type of check that should be used for the file back-

up:

1. If you want to compare the CRC

checksum of the backed up files with the CRC checksum

of the original files, select the Verify by CRC option button.

If you want to verify whether files have been changed after the backup, select the Modi-

fied option button.

If you want to verify whether all files have been backed up, select the Verify by contents

option button.

9. If you selected a drive backup, specify the type of check that should be used for the drive

backup:

1. If you want to compare the CRC checksum of the backed up drive with the CRC check-

sum of the original drive, select the Verify by CRC option button.

2. If you want to compare the original drive with the backup sector-by-sector, select the Sec-

tor by Sector option button.

3. Select the appropriate hard drive or partition from the lower area.
