Types of Home Network Backup
Several different methods exist for setting up and organizing backups using your home computer network:- network backups to CD-ROM or DVD-ROM disks
- network backups to a local server
- online backups to a remote hosting service
Network Backup to Disks
One simple way to back up your data is to "burn" copies onto CD-ROM or DVD-ROM disks. In this method, you can manually choose the individual files and folders you want to back up on each computer, then use the computer's CD / DVD writing program to make copies. If all of your computers have a CD-ROM / DVD-ROM writer, you do not even need to access the network.Most homes have at least one computer on the network without its own disk writer, however. For these, you can set up file sharing and remotely transfer data onto the disk over the home network.
Network Backup to a Local Server
As an alternative to burning multiple disks on possibly several different computers, some people opt to set up a backup server on their home network. A backup server contains a large hard disk (usually 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 which function as simple backup servers. Alternatively, more technically inclined homeowners may choose to set up their own backup server using an ordinary computer and home network backup software.
Network Backup to a Remote Hosting Service
Some Internet sites provide remote data backup services. Instead of making copies of data within the home like the above methods, these online services instead copy files from the home network to their servers over the Internet and store subscribers' data in their protected facilities.After signing up with one of these services, you first set up their network backup software application and most of the backups happen automatically thereafter. These services typically charge monthly or yearly fees based on the amount of data being backed up.
Comparing the Options for Network Backup
Each of the above methods has its advantages:Local Disk Backups:
- Pros - Full control over which files are backed up and when. Disks are relatively cheap.
- Cons - Disks are easy to steal or misplace. People often forget to backup frequently enough.
Local Server Backups:
- Pros - Automatic backup capability with suitable software. Frees up resources (disk burners) on the home computers.
- Cons - Server is in the same location as the computers and susceptible to the same theft/fire/flood risks. NAS devices are not cheap.
Remote Hosted Backups:
- Pros - Automatic backup capability. Servers are away from the home with lower risk from theft/disaster.
- Cons - Is an expensive option financially for large amounts of data. Relies on providers being reputable and provisions being made if their business shuts down.
Summary
Network backup systems allow you to protect personal computer data. Using your home network, files can be copied to CD-ROM / DVD-ROM disks, a local server you've installed, or an online service you've subscribed to. Pros and cons exist for each of these options.Many people do not take the time to set up a network backup system hoping they will never need it. Yet network backup need not be difficult to install, and it is a insurance policy for electronic data that is probably a lot more valuable than you think.
