问题解答

可以,可以通过从 Snapshot 策略中定义的 Snapshot 名称重命名 Snapshot 来保留 Snapshot 。

示例:

  1. 重命名 Snapshot :
    Cluster1::> volume snapshot rename -vserver svm1 -volume rename -snapshot 5minS.2020-09-16_1815 -new-name 5minS.2020-09-16_1815_RENAMED
  2. 第二天,重命名的 Snapshot 将一直保留,直到手动删除为止:
    cluster1::> volume snapshot show -vserver svm1 -volume rename
                                     ---Blocks---
    Vserver  Volume   Snapshot                  Size Total% Used%
    -------- -------- ------------------------------------- -------- ------ -----
    svm1    rename
              5minS.2020-09-16_1815_RENAMED       196KB    0%   33%
              5minS.2020-09-18_1330           144KB    0%   26%
              5minS.2020-09-18_1335           144KB    0%   26%
              5minS.2020-09-18_1340           288KB    0%   42%
              5minS.2020-09-18_1345           144KB    0%   26%
              5minS.2020-09-18_1350           232KB    0%   36%
              5minS.2020-09-18_1355           236KB    0%   37%
