+## Backup an application database
+Run like this example:
+```
+$ sh app-db-backup.sh 
+App name (inventory|catalog)> catalog
+```
+
+It will create a db dump file such as `catalog-db-20230714-110218-development.gz`
+
+## Restore a database backup
+`catalog-db-restore.sh` is multi-purposed script and includes a lot of steps for specific catalog use case. Use  `app-db-restore.sh` if you just want to restore a DB backup.
+
+First you need to create a new database, such as 
+```
+cf create-service aws-rds medium-gp-psql catalog-new-db -c "{\"storage\": 250, \"version\": \"12\"}"
+```
+Use the existing DB for correct db plan and storage size
+
+then run this script, providing the backup file and new DB name:
+```
+$ sh app-db-restore.sh 
+S3 Backup path> catalog-db-20230714-110218-development.gz
+New Service name> catalog-new-db
+```
