I can’t tell you how many different times I’ve had to fall back to a backup of a file, folder, or hard drive only to find that the backup doesn’t exist.
At that point, depending on the critical need for the backed up file/folder/drive, life is either a lot easier, or a lot more difficult.
Backup early and often. Those are words to live by. That’s why we’re thankful for applications like PC File Backup Professional.
