Syncing Files for Backup?

[jnalpak]

I'm looking to backup my music collection (200gb+) but dont want to purchase some big time backup system. I have an external 500GB on my server that i usually just run a copy/paste on but thats just not write and frags up the HD.

Does anyone currently use a sync' type tool to backup their files? Sort of like doubletake but not so damn expensive?

i found this product, - syncback

any other good ones out there?
