+# Basic settings #
+
+There are 2 defaults:
+
+```
+dir-localdumps = /var/iml-backup
+keep-days = 7
+```
+
+## dir-localdumps ##
+
+{string}
+
+The target directory for local dumps. It is used by 
+
+* the database dump scripts
+* the transfer script to store the client backups
+* the restore script
+
+Below that one a directory for the service will be generated; inside that one the database dumbs with scheme name and timestamp, i.e.
+
+    /var/iml-backup/mysql/mydatabase__20190827-2300.sql.gz
+
+## keep-days ##
+
+{integer}
+
+The number of days how long to keep dumps locally.
+
+Remark:
+To make a database restore its dump must be located at this directory. To restore an older database you need to restore the dump from duplicity first.
+
+If you have local Mysql daemon or Pgsql you can test it by starting 
+
+```
+# dump all databases
+sudo ./localdump.sh
+```
+
+
+```
+# show written files
+find /var/iml-backup
+```
