Yes I am using rsync extensively at home for personal backups. ZFS snapshots + send/receive are much more efficient, but ZFS is not suitable for VPS VMs with tiny amounts of memory allocated to them. I'm looking into deploying identical VMs with different providers located in U.S., UK, and EU. Then establish VPN with wireguard and synchronise IMAP mailboxes with Dovecot replication. Still trying to figure out the best architecture - active/passive or active/active. I probably do not want anything too complex as this tends to decrease reliability.
