ZFS send and recv	2022-07-23T07:00:00+05:30	false	true

Step 0000: Configure SSH Access

On the sender's system:

cd ~/.ssh/
ssh-keygen -t ed25519 -f zfs_send

echo "
Host hostname.localdomain
        Hostname <ip-addr>
        User root
        IdentityFile ~/.ssh/zfs_send
        Port <port>
" | tee -a ~/.ssh/config

---

On the receiving system:

sudoedit /etc/ssh/sshd_config

[...]
PermitRootLogin yes
[...]

user $ sudo -i

root # echo "zfs_send.pub" | tee -a ~/.ssh/authorized_keys

sudo systemctl restart sshd

This guide was possible because of the amazing documentation of Klara Systems.

Step 0001: Delegate ZFS administration permissions to unprivileged users

On the sender's system:

sudo zfs allow -u USER send,snapshot,hold POOL

On the receiving end:

sudo zfs allow -u USER compression,mountpoint,create,mount,receive POOL

Step 0010: Send

sudo zfs snapshot <vol>@sendtest
zfs send -v <vol>@sendtest | ssh hostname.localdomain zfs receive <pool>/backups/<vol-name>
