Backup/Restore
Possibly the most important concept in computing is that of backup. This is especially true regarding Internet safety.
The idea of backing up is to make a copy of your important data as a precaution against losing the original.
Many home users will make backups of important files to CDs or even DVDs whereas business users will typically have a more robust backup/restore strategy with expensive hardware and software.
Note: Some operating systems have the facility to take a dated snapshot of a fully working system. This snapshot can be used to restore the system back to this snapshot if something goes wrong later. This snapshot is called a restore point.
