+# sentry-util
+
+Script d'aide au suivi du cycle de vie de l'application Sentry.
+
+## Usage
+
+### Sauvegarde et restauration
+
+Deux commandes sont implémentées afin de permettre de sauvegarder et restaurer un environnement Sentry.
+
+#### Effectuer une sauvegarde
+
+Sur la machine hébergeant l'environnement Sentry:
+
+1. Couper l'application Sentry
+
+    ```
+    docker-compose down
+    ```
+
+2. Lancer la sauvegarde
+
+    ```
+    ./sentry-util backup
+    ```
+
+3. Redémarrer l'application Sentry
+
+    ```
+    docker-compose up
+    ```
+
+Le script va créer un dossier `backup-<YYYYMMDD>` dans le répertoire d'exécution. Ce dossier contient les données des différents volumes externes de l'application Sentry.
+
+#### Restaurer une sauvegarde
+
+Sur la machine hébergeant l'environnement Sentry:
+
+1. Couper l'application Sentry
+
+    ```
+    docker-compose down
+    ```
+
+2. Lancer la restauration
+
+    ```
+    ./sentry-util restore <YYYYMMDD>  # Où YYYYMMDD correspond à la date de la sauvegarde
+    ```
+
+3. Redémarrer l'application Sentry
+
+    ```
+    docker-compose up
+    ```
