There's a bunch. Some are better than others.

Here's a list, taken from (http://www.kimpl.com/1297/secure-online-backup-file-sync-ser...) which also has some reviews.

As others say, there's a difference between syncing and hosting; between levels of security; between ease of use; etc.

And obviously Tarsnap is great, for people who know what they're doing.
