What data protection is
Data protection means backing up data and being able to recover it. You protect
the data by making copies of it so that it is available for restoration even if the original is no longer available.
- Why data needs protection
Businesses need data backup and protection for the following reasons.
- Methods of protecting data
Depending on your data protection and backup needs, Data ONTAP offers a variety of features and methods to ensure against accidental, malicious, or disaster-induced loss of data.
- What online backup and recovery is
Data ONTAP creates online data backups to enable online data recovery. Online backup refers to backup data that is stored on disks rather than on tape.
- What the NVFAIL feature is
If NVRAM problems occur that compromise database validity, the NVFAIL feature can warn you and automatically rename the database so that it does not restart automatically. You can then ensure that the database is valid before restarting it.
- What a data loss disaster is
A data loss disaster is a situation in which service from one physical site (for example, a building or a corporate campus) on the network is lost for an extended period of time.
- How to protect data in a SAN environment
If the volumes contain logical units of storage (LUNs) created to accommodate integration into a storage area network (SAN) environment, you must carry out modified procedures to implement data protection using the following features described in this document.
- Policy-based automated data protection using Protection Manager
Typically, data and resource management is time consuming because it involves manual analysis and management of storage capacity, network bandwidth, schedules, retention policies, and other infrastructure variables. Protection Manager simplifies this work by employing configuration policies (that you can assign to multiple storage systems, volumes, or qtrees), convenient wizards, and automated verification of certain aspects of the data protection configuration.
