 **How much do share snapshots cost?**  
     Share snapshots are incremental in nature. The base share snapshot is the share itself. All subsequent share snapshots are incremental and store only the difference from the preceding share snapshot. You're billed only for the changed content. If you have a share with 100 GiB of data but only 5 GiB has changed since your last share snapshot, the share snapshot consumes only 5 additional GiB, and you're billed for 105 GiB. For more information about transaction and standard egress charges, see the [Pricing page](https://azure.microsoft.com/pricing/details/storage/files/).

+**Can I use my Azure file share as a *File Share Witness* for my Windows Server Failover Cluster?**  
+    Currently, this configuration is not supported for an Azure file share. For more information about how to set this up for Azure Blob storage, see [Deploy a Cloud Witness for a Failover Cluster](/windows-server/failover-clustering/deploy-cloud-witness).
