Today, I was backing up some files from my staging server on my 1and1 shared plan, and when I canceled the download my ftp client erased the files off the server representing a days work. I called 1and1 support to ask if they could restore the files. I wasn't expecting for them to say there was nothing they could do, but to my surprise, they have a seven day back up system that can be accessed through the control panel. Dreamhost has a backup system, but when I attempted to use it once the system returned an error, but it worked on 1and1. Thanks guys!
