Other features

Azure File Sync

  • Internal hash validation

Tip

Azure File Sync is meant as a permanent, hybrid solution for on-premises caching / sync of a number of Azure file shares. In that function, it provides zero-downtime cloud migration. If you do not plan on caching your Azure file shares on-premises, Azure File Sync is not a recommended migration tool. Refer to the Azure file share migration overview or the other partner tools described in this article.
