On: Ask HN: How do you backup your files without depending on a third party service?

[corv]

Two FreeNAS servers on premises and in different locations with ZFS replication.

Then use SMB, NFS, Time Machine, rsync, Syncthing, sftp or anything else you like to push data to one of the FreeNAS machines.

Periodic ZFS snapshots prevent common cases of PEBCAK and ransomware.

Fully redundant, encrypted & open-source solution that can saturate 10GbE!

Just wanted to leave this excellent tool here for those replicating ZFS:

If you have ecc memory and two locations this is probably the best option.

If you don’t have a second location you can still replicate to https://www.rsync.net with all the benefits ZFS provides.

ECC is highly recommended but even a low powered CPU will do.
