@Vadym Rybitskyy Welcome to Microsoft Q&A Forum, Thank you for posting your query here!
Firstly, apologies for the delay in responding here and any inconvenience this issue may have caused.
- What about file sync?
You can use the same share names on-prem. File sync will just extend their Fileshare to cloud sort of hybrid, although this will depend on your environment.
Note: servername\sharename on cloud - you can have same sharename but servername cannot be guaranteed because that's the storage account name
Windows Server Failover Clustering is supported by Azure File Sync for the "File Server for general use" deployment option. Failover Clustering is not supported on "Scale-Out File Server for application data" (SOFS) or on Clustered Shared Volumes (CSVs).
The Azure File Sync agent must be installed on every node in a Failover Cluster for sync to work correctly.
