Frequently Asked Questions about Application-Aware Writer Backup

What is VSS?


VSS is a subsystem within Windows to help manage taking point-in-time snapshots of data and applications.

Can Comet back up open files?


Comet can back up open files using VSS with the "File and Folder" protected item type when you enable the "Take filesystem snapshot" checkbox. The separate Application-Aware Writer booster is for other installed applications that provide a VSS Writer driver. You do not need the Application-Aware Writer booster to back up open files with Comet.

What is a VSS Writer?


A VSS Writer is a driver that is integrated with the VSS subsystem in Windows, to allow a backup job to be fully consistent with an application’s state. When you select a VSS Writer in Comet's "Application-Aware Writer" Protected Item type, Comet asks the VSS writer to produce an application-consistent backup of all its specific application data that is then made available to Comet.

What applications can I back up via a VSS Writer?


Microsoft SQL Server, Microsoft SharePoint, Microsoft Exchange Server, Microsoft Hyper-V, Oracle DB, and many more third-party applications all ship a VSS Writer driver with their product. By using the "Application-Aware Writer" Protected Item type in Comet, you can back up data from these applications in an application-consistent way.

How does the pricing for the Application-Aware Writer booster work?


Files & Folders backup is Comet's base offering. After adding your protected devices, you can choose additional boosters, such as Application-Aware Writer. The cost of protecting a single device with one Application-Aware Writer backup is $2 for Files & Folder backup + $1 for the Application-Aware Writer booster = $3/device per month (in USD)
