| Abstract: | The database system is very powerful in handling data, but it will be out of order due to the breakdown of the software and hardware. Thus, it is important to backup the database. On- line backup can be performed when the database is operated under the filing mode. To prevent various kinds of accidents, you should have a clear understanding of the process of the accident, and be aware of the loss of the data and the time tolerance. What's more, in performing the backup scheme, you should take into full considerations of the factors such as the ratio of quality to cost, and the simplicity, practicality, expansibility and the security of the system. |
