To ensure a successful backup, use the newest version of backup software. Set a time when the computer is functional and on. Break backup data into smaller sections. Avoid conflicts by making sure virus scans or other computer programs are not being done at the same time. Make certain backup copies have the same content as the original data file. Check that backup was successfully completed or failed. Follow up on the integrity of the backup file by periodically retrieving the backup file, open it on a separate system, and compare to the original file. Follow up to ensure backup is completed successfully.
