Hi Rich,

As you suggested i’ve created a new backup. As you told me that after the backup procedure the directory only contains .bak files, but i get the error that no database files where found. Also, in the log there is an error `Cannot open the storage 'component' because it does not exist in path: /data/nexus/sonatype-work/nexus3/db-tmp/component DB name="component"`  
Do you now what i have to do?

Regards, Will
