Backup basics: Three backup plans -- ten tape backup

Imation

Published: 02 Oct 2003

In a ten tape backup, you'll need four discs or tapes for your daily incremental backups, three discs or tapes for weekly incremental backups, and three discs or tapes for full monthly 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, 6, 7 = Friday backup of weekly file changes stored securely off-site. (Incremental weekly backup)

Disc/tape 8, 9, 10 = Full backup on the fourth Friday of each month stored securely off-site. (Full monthly backup)

One extra tape is used for an incremental backup if there is a fifth Friday in a month.
