Home Network Backup

A home network backup system maintains copies of your personal electronic data files in case of computer failures, theft or disasters. You can manage your own home network backups or choose to use an online service. Considering the impact of possibly losing irreplaceable family photos and documents, the time and money you spend on network backups is almost certainly a worthwhile investment.
Types of Home Network Backup
Several different methods exist for setting up and organizing backups using your home computer network: backups to CD-ROM or DVD-ROM discs
network backups to a local server
online backups to a remote hosting service
backups to CD-ROM or DVD-ROM discs
network backups to a local server
online backups to a remote hosting service
Backup to Discs
One simple way to back up your data is to "burn" copies onto optical (CD-ROM or DVD-ROM) discs. Using this method, you can manually choose the individual files and folders you want to back up from each computer, then use the computer's CD / DVD writing program to make file copies. If all of your computers have a CD-ROM / DVD-ROM writer, you do not even need to access the network as part of the backup procedure.

Most homes have at least one computer on the network without its own disc writer, however. For these, you can set up file sharing and remotely transfer data onto the optical disc over the home network.

Network Backup to a Local Server
Instead of burning multiple disks on possibly several different computers, consider setting up a backup server on your home network. A backup server contains a large hard disk drive (sometimes more than one for increased reliability) and has network access to receive files from the other home computers.

Several companies manufacture Network Attached Storage (NAS) devices that function as simple backup servers. Alternatively, more technically inclined homeowners may opt to set up their own backup server using an ordinary computer and home network backup software.

Network Backup to a Remote Hosting Service
Several Internet sites offer remote data backup services. Instead of making copies of data within the home as with the above methods, these online services copy files from the home network to their servers over the Internet and store subscribers' data in their protected facilities.
