Models

Unstructured! Stack of disks or media

! Minimal info aboutwhat was backed up, when! Easiest to implement

! Least likely for recoverability

Full + Incremental! Full backup,

followed by incremental backups! Restoration complicated:full backup + increments

to given time! Very common method

85

86


Continuous! Every change logged & backed up! Bytes or blocks saved, not files

FinalThoughts

Backup locally & off-site
