Between an external hard drive and RAID?

RAID = Redundant Array of Inexpensive Disks.  It consists of two or more disks, which can be either internal or external.  They are used together to provide protection against loss of data in case of disk failure.  A RAID is normally used on a server system, and not very commonly on a desktop.

You can back up do CD's or DVD's if you have a burner.  They're cheap, but only good for maybe five years, so not good for archival for the ages.

The traditional approach is tape backup.  This is still good, but kind of expensive.  You have to buy a tape drive, and the tapes aren't cheap.  They also eventually lose data, maybe in five to fifteen years.

You can save to a GMail account, or some other online storage space provider, as long as it's nothing too sensitive.

You can get another external hard drive, and copy to it from time to time.

The solution I mostly use is to copy important files between multiple computers.  Just make sure you have plenty of disk space.

Thanks! I am wading through all this information on network/server backup vs. external hard drives etc. Some videomaking sites discuss RAID whereas others dump it all directly to an external.

Any thoughts on a reliable backup solution?

It tough keeping up with the tech talk, since I am cloistered in a Mac World in some sense. I want a higher rate of transfer speed for sure.
emphasis mine:
A reliable backup solution is proportionally related to how sensitive/important your data is. At the higher end of importance is RAID (which gets hairy as there are about 5 levels/configurations).   If you simply want to back up your home videos an external hard drive with firewire(IEEE 1394) connection will probably give you the best bang for your buck on a MAC.  I say that because you can get a large capacity drive at a reasonable price and firewire offers good transfer speed.  After that all you need is software to manage the process and you're off and blazing.  Happy hunting.

RAID may or may not be a solution.  If you want on-site backup, either RAID or simple disk mirroring is great, though RAID can be complex and expensive.  The problem is, if your house burns down, it hasn't saved you.  For that, you need off-site storage, either by physically taking tapes or disks elsewhere, or via the net.

As in all engineering decisions, there are trade offs.
