## Step 0000: Configure SSH Access
|
||||||
|
|
||||||
|
**On the sender's system:**
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd ~/.ssh/
|
||||||
|
ssh-keygen -t ed25519 -f zfs_send
|
||||||
|
```
|
||||||
|
|
||||||
|
```bash
|
||||||
|
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
|
||||||
|
[...]
|
||||||
|
```
|
||||||
|
|
||||||
|
```bash
|
||||||
|
user $ sudo -i
|
||||||
|
|
||||||
|
root # echo "zfs_send.pub" | tee -a ~/.ssh/authorized_keys
|
||||||
|
```
|
||||||
|
|
||||||
|
`sudo systemctl restart sshd`
|
||||||
|
|

## Step 0001: Delegate ZFS administration permissions to unprivileged users
|
||||||
|
|
||||||
|
**On the sender's system:**
|
||||||
|
|
||||||
|
```bash
|
||||||
|
sudo zfs allow -u USER send,snapshot,hold POOL
|
||||||
|
```
|
||||||
|
|
||||||
|
**On the receiving end:**
|
||||||
|
|
||||||
|
```bash
|
||||||
|
sudo zfs allow -u USER compression,mountpoint,create,mount,receive POOL
|
||||||
|
```
|
||||||
|
|
||||||
|
## Step 0010: Send
|
||||||
|
|
||||||
|
```zfs
|
||||||
|
sudo zfs snapshot <vol>@sendtest
|
||||||
|
zfs sent -v <vol>@sendtest | ssh hostname.localdomain zfs receive <pool>/backups/<vol-name>
|
||||||
|
```
