* daily — around the “boy tapes”
* weekly — around the “father tapes”
* monthly — around the “grandfather tapes”

This tactic gives you having the ability to restore data in the a week ago, plus any Monday during the last month, plus any month as many monthly tapes as you’ve. Variations about this plan can be found, and supply a trade-off between the amount of tapes needed, and the amount of monthly tapes available.
5. Various kinds of backup
Various kinds of backups can be found in backup software.
* Full — all files, system data
* Differential — all files added or altered because the last full backup
* Incremental — all files added or altered because the last full, differential or incremental backup
* Daily — all files added or altered at the time from the backup
A Complete backup will copy all files and system data towards the backup media. It enables for that complete restore of data in one single tape.
Differential, Incremental and Daily are partial backups are made to reduce quantity of data backed-to the media, leading to faster backups. To revive data using one of these simple backups, the final Full backup tape may also be needed, together with every other partial backups because the last Full backup.
