GNU/Linux Desktop Survival Guide
by Graham Williams
Computers crash, disks become corrupt, data is lost, security is compromised. Today, computers are pretty reliable and it is rare to lose data (except through accidental deletion) but it can happen and usually when it is most inconvenient! Important work should always be backed up.
In this chapter we review approaches to backup and recovery. We begin with a review of recovering accidently delted files from a filesytem that is not backed up. Then we continue with simple approaches to backing up, including backing up to CD and the use of a commercial backup system called Legato NetWorker (also known as the Solstice NetWorker).
Alternatives include backup2l, backuppc, bacula, cdbackup, dar, and mondo.
