 ### Sauvegarde via snapshots
 
+Il faut donc avoir une directive `path.repo: ["/home/backup-elasticsearch"]` prise en compte par Elasticsearch avec un répertoire existant.
+Puis on crée 
+
+Créons un snapshot repository nommé `snaprepo` :
+
+~~~
+$ curl -XPUT 'http://localhost:9200/_snapshot/snaprepo' -d '{
+"type": "fs",
+    "settings": {
+        "location": "/home/backup-elasticsearch",
+        "compress": true
+    }
+}'
+{"acknowledged":true}
+~~~
+
 On peut ainsi créer régulièrement des snapshots pour les sauvegardes.
 
 Pour créer un snapshot toutes les heures, et en conserver 24 en permanence (notion de snapshots "roulants") :
 
 ~~~
 $ date=$(date +%H)
-$ curl -s -X DELETE "127.0.0.1:9200/_snapshot/foo/h${date}" | grep -v acknowledged..true
-$ curl -s -X PUT "127.0.0.1:9200/_snapshot/foo/h${date}?wait_for_completion=true" -o /tmp/es_snapshot_h${date}.log
+$ curl -s -X DELETE "127.0.0.1:9200/_snapshot/snaprepo/h${date}" | grep -v acknowledged..true
+$ curl -s -X PUT "127.0.0.1:9200/_snapshot/snaprepo/h${date}?wait_for_completion=true" -o /tmp/es_snapshot_h${date}.log
 ~~~
 
 Plus classiquement pour avoir un snapshot par jour :
 
 ~~~
 $ date=$(date +%Y-%m-%d)
-$ curl -s -XDELETE "localhost:9200/_snapshot/foo/snapshot_${date}" | grep -v acknowledged..true
-$ curl -s -XPUT "localhost:9200/_snapshot/foo/snapshot_${date}?wait_for_completion=true" -o /tmp/es_snapshot_${date}.log
+$ curl -s -XDELETE "localhost:9200/_snapshot/snaprepo/snapshot_${date}" | grep -v acknowledged..true
+$ curl -s -XPUT "localhost:9200/_snapshot/snaprepo/snapshot_${date}?wait_for_completion=true" -o /tmp/es_snapshot_${date}.log
 ~~~
 
 On peut ensuite purger les snapshots vieux de plus de 10 jours ainsi :
 
 ~~~
-$ cd /home/backup-elasticsearch/foo
-$ for i in $(ls -1d snapshot-* | head -n -10 | sed s'/snapshot-snapshot_//g'); do curl -s -XDELETE "localhost:9200/_snapshot/foo/snaps
+$ cd /home/backup-elasticsearch/snaprepo
+$ for i in $(ls -1d snapshot-* | head -n -10 | sed s'/snapshot-snapshot_//g'); do curl -s -XDELETE "localhost:9200/_snapshot/snaprepo/snaps
 hot_${i}"; done
 ~~~
