I need something covering both the old zfs and OpenZFS. I'm looking for the differences, any incompatibilities that might apply in my context. It'd be great if he has more recent stuff. >I use zfs-auto-snapshot for snapshot creation/ management, and homebrew >commands/ scripts for replication. The homebrew stuff is problematic. yeah homebrew I'm trying to avoid for lots of reasons. >I need to evaluate something like zfs-replicate (available as a FreeBSD >package of the same name): Thanks for the suggestion. Problem with zfs-replicate is its dependence on python, which from what I've observed historically, is a bit of a mess. On my desktop there's lots of ports still needed that are dependent on python2 even though upstream have retired it. They show up in reports as EoL'd due to python2; there's loads right now and the desktop builds its ports in poudriere weekly. What I'm looking for is something (ideally) written in sh. Or even perl. But even before that, need to understand incremental backups properly. Basically the backup needs to be (effectively) write-only. By that, I mean only added to. Maybe zfs snapshots aren't the way to go; maybe rsync in the backup direction only (apart from when something needs to be restored) would suit my context better. What do you think? --=20 J. --erl2uAFuAlkL2s4n Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE8n3tWhxW11Ccvv9/s8o7QhFzNAUFAmFXF6gACgkQs8o7QhFz NAXSSQ//ZEfS11RmyvAVlfiuU8XSf4mNMbckWxKm8g+REVmw4kgjwqQExzwYHpj0 dlJWdbEoKLPpb0zNOfNOHZRlP2f1vBxMRPv2PEw+mDrqxlPSPkRXKYoPXAjvZKUX bSerW6arerJkWBBTp/cv/gXv2g7QXZaENFn6AQRAD3vk+svtARV/4/jnFys4KZ4r P7bJXrrhgFc1ObVjx7nH+xO78htdPNKr02O6tShl99lS4TZ5XfKKxRhDW3Ig/iFZ 0DeqZKb/mF0/oeuJzoWBqHCe5EuJwtsBbJ96C1XI3FC7HS5NCXgeft41lteevFqO sh5mj1KCnoU4gGIu1e3iMQPq99hzw4JrBedZjg454OR2xfsQGdvbbFpdSa9QA1TD n9nsMKohe5ZCJyYF8XdLoJsocMH8TmgVApxw5rW6zvTsCj2bQY3rGBWV0G98dXTY rGrszxSVv9iayyiREL4ucSqgLNCKvnflHURBch/tJQYU9i/0yPRwJ/UMY5r80cv5 kWnr2xhAsAOEpI6B08nPWYC8GZP0R0h2gOr0mwKoOy8tRzP8X/PtmbsQeCkG5Pwk kLp9Un0RSoB88c6++5dYXAXjFgnzBbBDaIqs+J/Q9KqUTFsPHRED8vgkqL8YZgl3 jgIOWg84JzxAWbgfqD0TrrdrsSmMir4Cr6sd87k7la8BRZOBwfI= =wDTq -----END PGP SIGNATURE----- --erl2uAFuAlkL2s4n--
