Contrary to the other guy, I successfully backed up several gigabytes to my private FTP server, halfway across the globe.
Haven't tried "full restore" though, but was able to restore select files.
I'm loving the app 'cause it allows me to use my own FTP server, and doesn't insist on selling me some arbitrary storage; it does incremental backup rather well; and most of all - I love that it encrypts everything before uploading, so I feel additionally confident.
Scheduler works like a charm as well, so all in all I'm overly thrilled about it.
