I would exclude the /QPFNWSSTG from the SAVE 21 of the Hosting partition, because of time. Then you can bring the host and everything backup on the Hosting partition. Plus all the clients. Then, I would bring down each hosted (Client) partition, and backup their network storage spaces /QPFNWSSTG/client-storage-spaces. When done, you bring up the partition, and move to the next one. This will reduce downtime for everyone, but still insure you have the pieces to put a system back together.

Subject: Backing up guest partitions
I have been considering the various options for backing up guest partitions and wondered what other people do.
In my case I am considering backing up the individual hosted partitions using a quarterly option 21 and a backup strategy tailored to the use of each guest. I further plan to back up the host periodically, or as the host changes to capture the full system configuration. My current thinking is to have a full outage every 6 months. On one backup I will back up up everything, guest storage
(/QPFNWSSTG) included. On the other backup I am thinking of simply backing up the host and the server descriptions but excluding the /QPFNWSSTG directory to save time; I am still thinking this through. I am trying to get to a situation where I can recover a system either with the hosts intact, or with the hosts to be recovered separately or not at all.
In the instance where I backup up the guests with individual backup regimes I am trying to get a balance between preserving the guest configuration on the host but at the same time avoiding having to save and restore the network storage spaces when I will (potentially) be overwriting the bulk of the storage during the guest recovery process.
While considering this I also wondered if while doing a full system save the guest would remain operational if I took the option not to end all servers. I'm not in a position to easily test this so I wondered if they could remain operational. I'm starting to to think this might be OK.
So what do others do ? What strategies do you have for backing up hosting and hosted and hosted partitions ? What recover plans are your backup strategies supporting ?
