I got about halfway through the survey before realizing it was about workstation backup, not server backup. Time Machine + Dropbox makes workstation backup a solved problem. Slicehost Backup + Tarsnap makes server backup almost a solved problem. And I say almost because I don't like having no choice but to store my full bootable backups with the same provider that hosts my primary server. If I could store bootable weekly images off-site, I'd be golden.
