Issue

Paging files should be excluded from participating in replication, but no disks have been excluded.

Impact

Paging files experience a high volume of input/output activity, which will unnecessarily require much greater resources to participate in replication. This impacts the following virtual machines:

Resolution

If you have not already done so, create a separate virtual hard disk for the Windows paging file. If initial replication has already been completed, use Hyper-V Manager to remove replication. Then, configure replication again and exclude the virtual hard disk with the paging file from replication.
