Introduction

This article describes the improvements and issues that are fixed in the Azure File Sync Agent v4 release that's dated November 2018. Additionally, this article contains installation instructions for this release.

Improvements and issues that are fixed

  • Adds support for Windows Server 2019. To get this support, manually download the full installer release of Azure File Sync Agent v4 release from the Microsoft Download Center.

  • Adds a new date-based cloud tiering policy setting. This policy setting is used to specify files that should be cached if accessed in a specified number of days.

  • Fixes an issue in which cloud tiering can take up to 24 hours to tier files.

  • Improvement when adding a new server to an existing sync group. Files are now downloaded based on the recently Created\Modified date from other servers in the sync group.

  • Improves interoperability with antivirus and other solutions so that tiered files can now use the FILE_ATTRIBUTE_RECALL_ON_DATA_ACCESS attribute.

  • Fixes an issue in which servers are unable to communicate with the Storage Sync Service when application-specific proxy settings are used.

  • Fixes an issue in which deleting a server endpoint no longer causes tiered files to become unusable as long as the cloud endpoint is not deleted and the server endpoint is re-created within 30 days.

  • Improves unattended agent installations by enabling the ability to include an answer file.

  • Adds support for a volume-level restore option on servers that have cloud tiering disabled.

  • Improves sync so that it now supports bidirectional control characters.

  • Adds miscellaneous performance and reliability improvements for sync and cloud tiering.
