适用场景

  • ONTAP 9
  • Data ONTAP 7-模式

问题解答

从ONTAP 9.4开始、最大快照数已增加

  • 从ONTAP 9.4开始、一个卷最多可包含1023个Snapshot副本。
  • 一个SnapMirror目标卷最多可包含1019个Snapshot副本。

ONTAP 9.3及更早版本

下面说明了最大 Snapshot 副本数:

  • 一个FlexVol volume的255个Snapshot副本。

  • 如果FlexVol volume处于数据保护镜像关系中、则最大Snapshot副本数为254、因为系统会保留一个Snapshot副本、以供该关系在恢复操作期间使用。

  • 如果FlexVol volume处于磁盘到磁盘备份关系中、则最大Snapshot副本数为251。

  • 如果 无限卷处于数据保护镜像关系中、则最大Snapshot副本数将减少两个、因为数据保护镜像关系会使用两个Snapshot副本。
