摘　　要：对于一个重要的数据库来说,任何故障和恶意破坏带来的损失都是巨大的,所以数据库的备份和恢复子系统的设计一直是数据库应用系统中非常重要的功能.本文提出了一种在备份时间频率上做非线性化处理的灵活有效的备份方案,即稀疏备份方案,并采用定时自动执行的方式在UNIX平台上加以实现.Any failures and vicious destruction to an important database will bring great loss. It is very important to design a recovery subsystem which can keep the consistency and integral of a DB. Though many DBMS service recovery subsystem, DBA still need to implement it in details. This article presents an effective strategy named Sparse-Backup which has a non-linear backup frequency instead of a linear one. The SB is suitable and effective and has been realized on UNIX using timing self-motion strategy.
