Has anyone configured IntelliSnap backup on Cisco HyperFlex (HXDP 4.5)?

Hello Psaha, 

Currently it does not look like 4.5 is listed on our Supported Version list. I am not seeing any cases referencing this Version in our System so it would be hard to say if it will present any issues.

If you are currently on Version 4.5 you can attempt to get this setup and try the backups. If you are looking to upgrade to 4.5 I would recommend reaching our to your Account Team on this to see about the firmware version going through our Certification process before doing the upgrade.
