I have retrieved single files from the web interface. I have not needed a full restore, but if you do, the best way is probably to have them send it to you on a USB or HDD (and that costs extra). The first upload took over a week, but subsequent updates are happening all of the time. On an older PC (2009) I had to move it to daily (evening) backups instead of continuous. It does not (by default) backup literally the whole machine (although you can fiddle with options to get it to do that). It's set up to do your data (not OS or Applications). It does not provide a bootable clone. I strongly suggest you also have a full bootable backup locally and treat BackBlaze as disaster recovery. I have a Mac and use TimeMachine -- but anything that makes you a bootable drive (or could restore to one) is fine.
