Data access management

Data ONTAP enables you to manage access to data.

Data ONTAP performs the following operations for data access management:

• Checks file access permissions against file access requests.
• Checks write operations against file and disk usage quotas that you set.

  For more information, see the Data ONTAP File Access and Protocols Management Guide.

• Takes Snapshot copies and makes them available so that users can access deleted or overwritten files. Snapshot copies are read-only copies of the entire file system.

  For more information on Snapshot copies, see the Data ONTAP Data Protection Online Backup and Recovery Guide.
