# Compute: Windows VSS Support for Application Consistent Snapshot

<p class="">Exoscale Snapshot now support <b>application consistent backups for Windows instances</b> using Microsoft Volume Shadow Copy Service (VSS).</p>

<p class="">When application consistent snapshots are enabled, Windows safely prepares the system before the snapshot is created. This means the data is properly written to disk, ensuring clean, reliable backups.</p>

<p class="">Instead of basic crash-consistent snapshots, you now get application consistent backups that are ready to restore for Microsoft workloads like SQL Server, Exchange, and file services.</p>
