Backing Storage

The type of back up storage that I am mainly looking at is known as “local backup”. Local backup is any backup where the storage device is kept close at hand. Typically, the storage device is connected to the source computer being backed up or is connected through a local area network to the source being backed up.

Examples of Local Backups
•Internal hard drive
•External hard drive (desktop or portable)
•Optical drives like CDs, DVDs and Blue Ray discs
•Solid state drives like USB memory sticks or Flash Drives
•Backup to a shared folder on another computer over the network
•Magnetic tape drives

•Good protection from hard drive failures, virus attacks and accidental deletes.
•Very fast backup and very fast restore.
•Storage cost can be very cheap when the right storage medium is used, eg. External hard drives.

Since the backup is stored close by to the source, it does not offer good protections against theft, fire, flood, earthquakes and other natural disasters. When the source is damaged by any of these circumstances, there’s a good chance the backup will be also damaged.

memory sticks, CDs and other forms of local backup can be easily mis-placed
