Doesn’t sound like backing up, but keeping your stuff massively in sync. What happens if you discover something is missing or corrupted after 6 months?

If it's not something super critical in my experience the simpler solution is better for longterm or fool-proof backups. E.g. if I use some special backup software that creates incremental archives or whatever, and then I die... My family would have absolutely no idea how to access that data. While with a normal NTFS partition and data on an external HDD they could just plug it in some PC and look at the family photos.

  I use a rsync script that does incrementals but keeps full copies of each backup. Although mine is significantly different, it is based on http://www.mikerubel.org/computers/rsync_snapshots/ http://www.mikerubel.org/computers/rsync_snapshots/ by Mike Rubel.

  It really depends on what we're comparing this to. If one compares it to a commercial solution that allows backing up to user-owned storages, then the commercial solution is simpler while having more functionality (including versioning).

The ZFS clone should deal with that via regular snapshots.

  Only if you have infinite storage space.

    Sadly, like any other option, ZFS can't magically create more storage space. People usually do something like keep hourly snapshots for a week, weekly snapshots for a few months and monthly snapshots for a year. My policy with data is similar to real life things: if I didn't notice it gone for a whole year then I probably don't need it. Are you perhaps hinting at using offline storage for long-term archival? What options are there? Tape? As far as I know, keeping hard disks online is still the best way to achieve this, sadly.
