There are also several options to backup only files which match the saved backup criteria, and have been recently modified. These options work well with another option to save each backup in a separate folder on the backup disk automatically named for the date and time, so you can make small backups of your recently modified files on a regular basis, and save them all to the same backup disc without overwriting the older backups.
Backup To DVD/CD/Flash and Backup Made Simple can also compress files on the backup, and if necessary split large files across multiple discs. Files backed up this way obviously need to be restored using the "restore" option in our backup software rather than simply copying or opening then on the backup disc with directly with some other software, as is normally possible with files backed up with our backup software.
