NetApp Snapshot Summary
Use Quick Search to find a template, report or dashboard by name. Search is case insensitive, supports partial entries, and will display a list of potential matches.
As you enter the name in the Search field, up to 10 potential matches are displayed. If the template, report or dashboard is shown, you can select and run it directly from the match list. You can also click All Items in the match list to go directly to the Search Results.
Use the Explorer to browse through the StorageConsole templates, dashboards and reports. The navigation pane displays templates organized by products along with user-created, and system folders. This report is located here:
NetApp snapshots use pointers to reference the blocks where the data is stored, thereby using a minimal amount of capacity. A snapshot captures a point-in-time image of the file system data. When the next snapshot is taken, the pointers will reference other blocks, as the file system data blocks have changed in the interval between snapshots. Therefore, the access time provides the time reference for the snapshot block usage. Snapshots provide a read-only source of data for backups to tape.
