When using Azure File Sync to migrate files from on-premises Linux servers, what is true?

Azure File Sync is designed to extend on-premises file servers to Azure, enabling efficient file synchronization and cloud backup. When utilizing Azure File Sync to migrate files, it is indeed true that this service can synchronize files.

With Azure File Sync, users can keep their on-premises file shares in sync with Azure, allowing for the seamless integration of data between local storage and the Azure cloud. This capability is especially beneficial for hybrid cloud environments where organizations may want to maintain their existing infrastructure while taking advantage of cloud benefits such as scalability, durability, and access from multiple locations.

The other options do not accurately reflect Azure File Sync's capabilities: it is specifically designed to work with Windows servers, whereas Linux systems would need to use alternative methods or tools for integration with Azure File services. Additionally, there is no requirement to convert files prior to migration, nor does Azure File Sync only allow for partial file migrations. Rather, it works by synchronizing entire files and maintaining their integrity throughout the process.
