+# Backup your data
+
+It's possible, and very easy, to backup all MIND data. This way, you can recover data if something goes wrong, port your instance over to an other computer or run redundant instances.
+
+## Backing up the data
+
+It's as simple as making a copy of the database file and storing it somewhere safe.
+
+1. Stop MIND, if it's still running.
+2. Go inside the docker volume of the container (most likely `mind-db`) or the mapped folder.
+3. Inside the volume/folder, you'll find the `MIND.db` file. Make a copy of this. That's all you need.
+4. You can now start the instance back up.
+
+The database file contains all data and is the only thing needed to keep a complete backup of your MIND instance.
+
+## Recovering the data
+
+It's as simple as putting the database file in the database folder and restarting the instance.
+
+1. Stop MIND, if it's still running.
+2. Go inside the docker volume of the container (most likely `mind-db`) or the mapped folder.
+3. Inside the volume/folder, place the database file that you backed up.
+4. You can now start the instance back up. Everything should be recovered.
