Restoring from Snapshots on the FluidFS can be done by changing into the .snapshots directory at any level within a FluidFS file system. There will be a number of different directories which have the prefixes hourly_, daily_ and weekly_. You can change your directory to the snapshot that will provide the necessary files depending on when you deleted them. Once you change the directory you should be in a exact copy of the path that you started in when the snapshot was taken. The snapshot is read only so please just copy any files or folders back into the places you want them restored.
