 1. File consists of blocks written to a volume:

+   ![A diagram of three files against four grey verticals bars, labeled time, volume, files, block.](../media/azure-netapp-files/single-file-snapshot-restore-one.png)
 
 2. A snapshot is a copy of the pointers that represent the files:

 3. Files on the volume continue to change and new ones are added. Modified data blocks are written to new empty data blocks on the volume:

 4. A new snapshot is taken to capture the new changes and additions.  Each volume supports up to 255 snapshots:

 5. When a single file is restored in-place (`file2`) or to a new file in the volume (`file2`), only the pointers to existing blocks previously captured in a snapshot are reverted. This operation eliminates copying any data blocks and is near-instantaneous, irrespective of the size of the file (the number of blocks in the file).
