当前,企业在其IT规模不断扩大的过程中,缩短备份窗口的通用方法,是在系统设计过程中采用一种超出现实需要的解决方案,采用多台备份服务器连接多个磁带驱动器。另一种方法则是尽可能减少完全备份的次数。尽管这些方法将有助于提高备份速度,但却会使恢复流程更为缓慢和麻烦。就传统方法而言,生产应用环境的增长是由昂贵的主存储来吸收和消化的。随着主存储要求的不断提高, Currently, the common way for businesses to shorten their backup windows as their IT footprint grows is to adopt an out-of-box solution to the system design process, using multiple backup servers to connect multiple tape drives. Another approach is to minimize the number of full backups. Although these methods will help improve the backup speed, but will make the recovery process more slow and trouble. In the traditional approach, the growth of the production application environment is absorbed and digested by expensive primary storage. As the main storage requirements continue to increase,
