 ### Mounting folder/ volume
 
 It is possible to mount an empty folder to /opt/iobroker during first startup of the container. The startup script will check this folder and restore content if it is empty.
-Since v4.1.0 it is also possible mount a folder filled up with an iobroker backup file (for example created with backitup adapter) named like this: "iobroker_2020_01_06-01_09_10_backupiobroker.tar.gz".
-The startup script will detect this backup and restore it during the start of the container. Please see container logs when starting the container for more details!
+Since v4.1.0 it is also possible mount a folder filled up with an iobroker backup file created using "iobroker backup" command or backitup adapter. Please take care of the name of your backup file ending like this: "*_backupiobroker.tar.gz".
+The startup script will then detect this backup and restore it during the start of the container. Please see container logs when starting the container for more details!
 
 Note: It is absolutely recommended to use a mounted folder or persistent volume for /opt/iobroker folder!
