You can perform three things if a backup is already exists: ✓ Automatically create a new backup file: As long as you have the disc space, doing this is advised. It will change the backup file's name by appending a sequential number. You should keep many copies of your backup on hand. ✓ Overwrite the existing backup file: There is only one backup version left after each backup has been overwritten. As a result, in the event that a backup is flawed/corrupted, you have no other options. So, we do not advise choosing this option. ✓ Stop the backup process: Any backup files with the same name present in this same location will cause the procedure to terminate. The log file will receive a new entry.
