+Sqlite files can be located anywhere in the filesystem. That's why the
+cannot be located with an auto detection. You need to define them in
+the file jobs/backup-dbfiles.job first.
 
-Remark:
-To make a database restore its dump must be located at this directory.
+Per database file set a line with the `sqlite = ` prefix
 
-To restore an older database you need to restore the dump from the filke backup first.
-
-If you have local Mysql daemon or Pgsql you can test it by starting
-
-```
-# dump all databases
-sudo ./localdump.sh
+```text
+sqlite = /var/lib/whatever/sqlite-database_01.db
+sqlite = /var/lib/somewhere/else/db.sqlite
 ```
 
-```
-# show written files
-find /var/iml-backup
-```
