Data availability is one of the most crucial issues in data management. When data is not available, it adversely affects the enterprise operation until that data is restored. There are several ways to protect data availability in the event of hardware, software, or power failure. Backups and redundant hardware help to improve data availability during hardware issues or failures. However, the process of creating and storing backups should be reliable and quick. Replication duplicates data between storage systems to facilitate data availability during disaster recovery.
