Backup Data stored in files is often valuable so companies are keen to prevent it’s loss. The easiest way to do this is to make a copy of the data and keep it in a secure location (off site to protect from fires).

Backup, how often? No right answers! Backups could be expensive and take time so a compromise needs to be struck. A file this altered a lot will need backing up more regularly than one that never changes.

Types of backup Normal – Copies all selected files to the selected medium. Incremental – Only changes files that have changed since the last backup.

Archiving If data is no longer being used (ie your data when you leave sixth form) you may not need it to be readily accessible. BUT You don’t want to get rid of it (ie in case a student wants a reference) so you create an ARCHIVE of the data you can access if you want it.
