Restoring conf

You can now restore your conf from backup. You got to restore the following dirs:

• /etc/openhab2
• /var/lib/openhab2

Starting openhab

You should now be able to start openhab2. FIRST BOOT WILL BE SLOW (5 mintues)!!!

If things still do not work

You can manually check that the following folders are restored:

* /etc/openhab2                                  # Conf dir. It's on github. That's easy.
* /var/lib/openhab2/.ssh/                        # So it will be able to turn on and off the NAS
* /var/lib/openhab2/config/org/openhab/          # During the next boot it will install what's needed and remove what's not
* /var/lib/openhab2/persistence/                 # Graphs will work now
* /var/lib/openhab2/jsondb/homekit.json          # Homekit configuration, then you won't have to add it back to iOS devices
* /var/lib/openhab2/influxdb.cfg                 # InfluxDB conf. It's linked from /etc/openhab2 because it contains passwords

Old guide

The old guide is in RECOVERY.md file. All its information should be here but you can check it out.

Cron and scripts

First restore the crontab of the users (they're in the backup):
