Although compression saves disk space, it can add effort. 尽管压缩可以节省磁盘空间,但是也会增加工作量。
Data document compression reduces the space needed to store your application's data. 数据文档压缩降低了存储应用程序数据所需的空间。
For example, you can use compression to save media space, use cloning to duplicate the archive for safety reasons, or restore the data onto another server instance. 比如,可以通过压缩来节约介质空间;或者出于安全的原因,通过克隆来复制存档;再或者将数据恢复到其他服务器实例中。
Compression reduces disk space needs, which often leads to lower disk I/ O and increased buffer pool hit ratios ( because compressed pages allow more data to be cached). 压缩可以减少所需的磁盘空间,这常常会减少磁盘I/O,增加缓冲区池的命中率(因为压缩的页面允许缓存更多数据)。
However, you do not need to enable compression to estimate how much space compressing your data would save. 但是,在评估数据压缩会节省多少空间时,不需要启用压缩。
After upgrading the drive, you can use DriveSpace's enhanced compression methods to maintain free space while you work. 升级驱动器后,您可使用磁盘空间管理增强的压缩方式,这样可以在您工作时保持可用空间。
