Site Collection backup failure when "includemysites" is set to FALSE

Apr 27, 2013 at 3:05 PM
I have a Farm with some Web Application and Site Collection, and one site collection has also sole personal site configured: if I set the "includemysites" to FALSE, the script does not backup the Site Collection, therefore I need to set it to TRUE (but in this case the backup will be done also for any personal site).
Is this an expected behaviour or a bug?
