DATA BACKUPHow often you will make the backup depends on the data that needs to be backed up. If your running a network with critical data on the servers, then daily backups might not be enough.You may need to include some of the things like:
  • The duration of time you spend on your computer
  • How much the data on your computer changes

If it is just small data (music files, photos, e-mails) then monthly backups will suffice. However if it is more important larger data's (tax audit) need to be backed up more often.

Backups can be stored in devices like:

  • USB flash drives
  • Hard disc drives
  • Optical disc drives
  • floppy disc
  • Memory cards
These are the places wherethe data can be transferred to use away from the computer:
