I've just signed up to Mozy Unlimited Backup in December. I trialled 2GB for free and now since we have enough upload speed, I've dived in and bought a subcription. It costs $4.95 per month.
I've heard some good stories about Mozy improving their services lately and my friend Steph has many a story about how Mozy saved her from losing data. She's even had them send external hard drives over to her. Which, though it costs extra, was a convenient way to get data back when it is multiple gigabytes.
Over the years I've used floppy disks, CD's, DVDs, USB sticks and external hard discs to back up my files. I do still use an external HDD, but with so much data (and the fact that I don't like to use the system backup on my computer, so I do my backups manually), Mozy seemed like a simple thing to add to my backup regime.
I have set it up so that Mozy throttles the bandwidth during peak times and unthrottle it during our off-peak times (2am-8am), to ensure we don't go over our monthly limit. It seems to be working well with 23.1Gb uploaded as I write this.
If you are interested, you can try the service before you buy - Mozy give you 2GB Totally Free.
