A snapshot is a listing of files (including their name, hash, and location) from one or more computers. You can use a single snapshot or a combination of snapshots as the baseline for a drift report.
You can use filters to generate exactly the file list you want and then take a snapshot of that list of files. There are several locations in the console from which you can create snapshots. After a snapshot is created, you can add or remove files from it as necessary.
Only Power Users, Administrators, and users in custom groups with view and manage snapshot permissions can create, modify and delete snapshots.
