但是前面又寫Support for backup of Cluster Shared Volumes

您只看了前半部, 卻沒看後半部....

後半部他寫得很清楚, 雖然前面講支援CSV, 不過不是全面支援, 以下是不支援的例外狀況:

Limited support for backing up CSVs as follows:
Virtual machines hosted on CSV’s cannot be added as part of backup configuration

Windows Server Backup has to be configured on all nodes to ensure that backup and recovery will be available in the event of a failure on one of the nodes in the cluster.

Volumes recovery not supported

Security access control lists are not applicable on CSV file service root. Therefore, file recovery to the root of CSV volume is not supported.

工程師的想法或許只有 0 or 1, 也就是: 只有 100% 的功能齊全, 才叫做有支援;
但是行銷的想法完全不同, 他們只要能沾上一點邊, 即使只有 1% 功能, 也會對外聲稱有支援..

所以, 工程師千萬要看清楚各種但書, 不要只看了前面, 就理所當然的推論自己想像的結果...
