1.备份：
备份是指存储原始数据的副本，以备数据丢失时使用。备份被认为是数据保护的方法之一。组织的重要数据需要有效备份，以保护有价值的数据。备份可以通过单独存储原始数据的副本或存储设备上的数据库来实现。有各种类型的备份可用，如完整备份、增量备份、本地备份、镜像备份等。
备份示例可以是 SnapManager 对数据库中的所有内容进行备份。
2. 恢复：
恢复是指通过一些过程来恢复丢失的数据。即使数据被备份仍然丢失，所以它可以通过使用/实施一些恢复技术来恢复。当数据库由于任何原因发生故障时，就有可能丢失数据，因此在这种情况下，恢复过程有助于提高数据库的可靠性。
Recover 的例子可以是 SnapManager 将数据恢复到最后一个事务。
备份和恢复的区别：
| S.No. | BACKUP | RECOVERY |
|---|---|---|
| 01. | Backup refers to storing a copy of original data separately. | Recovery refers to restoring the lost data in case of failure. |
| 02. | So we can say Backup is a copy of data which is used to restore original data after a data loss/damage occurs. | So we can say Recovery is a process of retrieving lost, corrupted or damaged data to its original state. |
| 03. | In simple backup is the replication of data. | In simple recovery is the process to store the database. |
| 04. | The prior goal of backup is just to keep one extra copy to refer in case of original data loss. | The prior goal of recovery is retrieve original data in case of original data failure. |
| 05. | It helps in improving data protection. | It helps in improving the reliability of the database. |
| 06. | Backup makes the recovery process more easier. | Recovery has no role in data backup. |
| 07. | The cost of backup is affordable. | The cost of recovery is expensive. |
| 08. | It’s production usage is very common. | It’s production usage is very rare. |
| 09. | Example of Backup can be SnapManager makes a backup of everything in database. | Example of Recover can be SnapManager recovers the data to the last transaction. |
