Title: Check conf backup integrity

* Check backup integrity by listing the tar file, throw InvalidData exception if the tar is corrupted
* Retry making the configuration backup if the conf backup process produced a corrupted backup
* Send the checksum of the conf backup when pushing to check its integrity on server side
