I have a bash script called syncoid-job which boils down to a barebones -
#!/bin/bash
syncoid --no-sync-snap --sendoptions=w --no-privilege-elevation $SYNOIC_USER@$SERVER:tank/encrypted/nas tank/encrypted/nas
I want to run this script hourly but as my user (notice the no-privilege-elevation flag)
First - create a systemd unit file at /etc/systemd/system/syncoid-replication.service
[Unit]
Description=ZFS Replication With Syncoid
[Service]
Type=oneshot
ExecStart=/$HOME/dotfiles/syncoid-job
User=$USER
Group=$GROUP
[Install]
WantedBy=multi-user.target
Then we save the unit file, enable the service, and then start it
systemctl enable syncoid-replication.service
systemctl start syncoid-replication.service
Note this will run that script... so be ready for syncoid to do its thing
Now for the timer... We create /etc/systemd/system/syncoid-replication.timer
[Unit]
Description=Run syncoid-replication every hour
[Timer]
OnCalendar=hourly
[Install]
WantedBy=timers.target
Hit it with a systemctl enable syncoid-replication.timer and you're in business!
