+# Backup
+
+## Database backup
+
+UnitTCMS uses SQLite for data persistence. Therefore, backing up the DB is simply backing up the SQLite DB file.
+
+Please backup the file `backend/database/database.sqlite`
+
+## Backup of uploaded files
+
+Uploaded files are managed separately from the DB. If you have uploaded files, you need to backup them too.
+
+Please backup the files under `backend/public/uploads` directory.
