This is a workaround to fix the error for backup-manager
can't locate object method "add_key_filename" via package "0"

This error is raised bec no propper Net::Amazon::S3 initialization.

To solve this you must enter the host parameter to where the API will authenticate:

/usr/bin/backup-manager-upload on line 870 you need to change:

This:
		my $s3 = Net::Amazon::S3->new(
			{   
				aws_access_key_id => $user,
				aws_secret_access_key => $passwd,
				timeout => 300
			}
		);

To This:
		my $s3 = Net::Amazon::S3->new(
			{   
				host => 's3.sa-east-1.amazonaws.com',
				aws_access_key_id => $user,
				aws_secret_access_key => $passwd,
				timeout => 300
			}
		);

note the host parameter is set to the S3 host endpoint to use.
