+### Backup and Restore
+
+Planka comes with two scripts that allow for manual backup and restore when running Planka with docker-compose.yml.
+Backups can be triggered with `backup.sh` which will export the Database, User Avatars, Project Backgrounds and Attachments into a single tgz file.
+
+```
+$ ./backup.sh
+Exporting postgres database ... Success!
+Exporting user-avatars ... Success!
+Exporting project-background-images ... Success!
+Exporting attachments ... Success!
+Creating final tarball 2023-01-17T15-37-22Z-backup.tgz ... Success!
+Cleaning up temporary files and folders ... Success!
+Backup Complete!
+```
+
+The resulting backup can be restored using the `restore.sh` script.
+
+```
+$ ./restore.sh 2023-01-17T15-37-22Z-backup.tgz
+Extracting tarball 2023-01-17T11-10-54Z-backup.tgz ... Success!
+Importing postgres database ...
+
+[Many lines of postgres output]
+...
+
+Success!
+Importing user-avatars ... Success!
+Importing project-background-images ... Success!
+Importing attachments ... Success!
+Cleaning up temporary files and folders ... Success!
+Restore complete!
