When attemping to perform a backup, either full or with the --test parameter, you get the following error:
ERROR Fail testing scp server, exception=cannot concatenate 'str' and 'NoneType' objects
This happens when the --path= parameter is not supplied. Even if you leave it blank, the command will only be successful if the --path parameter is given in the backup command.
Example:
localhost> backup --user=admin --host=10.1.2.3 --protocol=scp --password=symantec --debug --path= --test
...
INFO Succeed running backup.
localhost> backup --user=admin --host=10.1.2.3 --protocol=scp --password=symantec --debug --test
...
ERROR Fail testing scp server, exception=cannot concatenate 'str' and 'NoneType' objects
