FileSlinger™ Backup Reminder 8-20-04: Network Backups
Dear FileSlinger clients, colleagues, and friends:
More backup news next week,
Sallie
It's that time again—time to protect your data against the inevitable computer disaster. And it is pretty much inevitable. Drive failure seems to be on the increase and often occurs at about the two-year mark, but might happen even sooner, depending on everything from the manufacturer to whether it gets adequate cooling. If you're really lucky, a hard drive might last you 5 or 6 years.
The other night I got to watch the Ur-Guru making a network backup of a client's laptop in order to reformat the drive. The simple version of how this works is:
Transferring data over a network is much faster than writing it to a CD or to a USB or even Firewire drive. It can also spare you having to get an external drive, as long as you have more than one machine on your network and the machine you want to put your backups on has lots of extra hard drive space.
It is possible that every machine on a network could go down at one time (fire, flood, earthquake, etc), just as it's possible that both your computer and your external drive could be destroyed at the same time. But it's not nearly as likely that two computers will die simultaneously as that one drive will fail when another is fine.
There can be some tricky bits involved in setting up network backups, depending on your hardware, and a Ghost backup won't work over a wireless network. (Wireless networks are much slower than cable networks anyway, even if you don't notice this in your day-to-day e-mail and web browsing.) But they can still be a good option for anyone who already has a home or office network set up.

- Plug the computer to be backed up into your network. (This machine had a built-in network port, so that was easy.)
- Designate a network drive on which to back up the machine. (Windows calls this "mapping" the drive.) This actually took some special utilities because the backup program we were using, Norton Ghost, works outside the Windows environment.
- Run your drive-mirroring software.
