Minimum Security Rotation System

The absolute minimum backup schedule is the use of two media sets, and rotating them on alternate backups. This gives you at least protection against relying on a single backup media set, and eliminates the chance of a hard disk crash during backup leaving you with nothing at all. It is still not great protection, since the retention period is very low, and there is no provision for off-site media storage.

If you use this type of scheme, you need to decide how often to do the backup. The longer you go between backups, the longer you put at risk the changes since the last backup. For many people who use their systems little enough that this minimum scheme makes sense, doing backups weekly is more than sufficient. For others, daily backups make more sense. If you do need daily backups however, I suggest a more comprehensive rotation scheme than this one, which is very limited in many different respects.
