Backup basics: Three backup plans -- six tape backup

In a six tape backup, you'll need four discs or tapes for your daily incremental backups, and two discs or tapes for full weekly backups:

Disc/tape 1 = Monday backup of daily file changes. (Incremental backup)

Disc/tape 2 = Tuesday backup of daily file changes. (Incremental backup)

Disc/tape 3 = Wednesday backup of daily file changes. (Incremental backup)

Disc/tape 4 = Thursday backup of daily file changes. (Incremental backup)

Disc/tape 5 = Odd week Friday backup of all files, stored securely off-site. (Full backup)

Disc/tape 6 = Even week Friday backup of all files, stored securely off-site. (Full backup)
