> I need something that would keep watch on all the files on the system (see inotify) to avoid continuous rescans of the disks Inotify (on Linux, and fanotify wouldn't be enough, since the backup tool would have to track file deletions as well) is the only way to have seamless background backups I tried to use other tools in the past, like duplicity... But having a scan every hour that takes several minutes and has noticeable CPU usage is a deal breaker (and having a backup scheduled less frequently than that is also a dealbreaker, since you cannot rely that the laptop would be up an running at a certain time during the day) (Crashplan also does a full rescan, but it's not strictly necessary... It's basically needed if the backup daemon crashed or was shutdown, or stuff had been changed on the filesystem while the OS was off, so that sanity check rescan can actually wait a few days)
