Data at rest protection

There a few ways to prevent a loss or theft of data that is stored. Theft of the data can be prevented by implementing encryption of the data. Even if an intruder is able to access the data, it will not make sense. Backup solution means that a version of data is available in the backup. It is important to have proper data included in the backup, test the backups and store backup in a secure offsite location, since data in backups maybe sensitive. Backups need to be tested regularly to ensure that they work. Redundancy at hardware level means that multiple copies of data is made and it is located on more than one server. Snapshots allow a user to go back to a version of a file that was available on certain day. It is possible to implement redundancy of the data for real-time access to it. It can be done by having data stored in multiple servers (ideally locations) or disks.
