B Application aware VSS backups
When performing application-aware VSS Backups (Volume Shadow Copy Service) for virtual machines on a
Hyper-V host, the backups might fail on a Nutanix share if more than 1000 files exist in the container. The
Nutanix NFS master may experience a timeout triggered by the creation of a list of "disk shadow" files after
the snapshot is taken.
B.1 Solution
Create a new container on the Nutanix cluster and storage-migrate the VMs to this new container.
Note: Nutanix recommends storing less than 50 VMs per container if backups are using Microsoft VSS on
Hyper-V for application consistency.
For more information, refer to Nutanix KB #000002506 (Nutanix Portal log in required).
