I came to the Knox website because I am looking for a encrypted backup software that could work with a distant server. I read the Q&A and saw the video. The vault aspect of it is well known to me since I am regularly using the Disk Utility. But I am still in the blue regarding the backup capabilities of Knox. Could any one enlight me, please?

Hi. Knox can backup to most volumes you mount and access through the Finder, but it will only use the faster incremental backup feature if the destination volume is local (a regular drive connected to your Mac) and formatted as Mac OS Extended (HFS+). Backing up large vaults through slow connections is, well, slow at the moment unfortunately.
