Using USB memory sticks for backups

I've started backing up onto a 2GB memory stick. Is this a safe method?
Martin James

USB memory sticks, CompactFlash and SD cards are good for short-term backups if you don't have an external hard drive, but they can be corrupted and lose data. Also, to avoid overwriting backups, I'd rather you used two memory sticks and alternated them. However, I'd still recommend making a CD-R backup every month or so, as an archive. CD-Rs are cheap and don't take up much room. Even if you throw most of the old discs away, you can still keep multiple backups of data going back years. And one day, you might need them.
