Commvault 正在尝试将 atime 设置为小于 （Current time） + （Retention-lock min-retention-period） 的值。
 

缩短最短保留期或设置 Commvault 以将 atime 设置为晚于设置的现值的值。

Configuring WORM Storage Lock 

Retention Lock、Compliance Lock、Software WORM、WORM Copy →所有这些都是指相同的 CommVault 软件级 WORM 保护。它阻止删除具有有效作业的作业、客户端、备份集或子客户端，还会阻止缩短保留期。
在版本 11.30 之前，使用 Java 控制台在存储策略拷贝级别启用 WORM。或者，对存储池中的所有拷贝使用保留锁定工作流。
从版本 11.30 开始，该选项已重命名为 'Compliance Lock“以避免与 WORM 存储混淆，可在命令中心和 Java 控制台的存储池属性下找到。选择切换开关 "Compliance Lock" 在存储池上启用此功能。 
 
WORM 存储→指硬件级（存储供应商端）WORM 保护。使用此选项时，数据会在存储端锁定，以防止从存储端进行任何直接删除和修改。
我们自动启用 "Compliance Lock" 启用 WORM 存储以防止保留更改与存储端锁定保持一致时。
之前，11.30 →使用 "Enable WORM Storage" 工作流来启用此功能。
从 11.30 →开始，我们在 Command Center 和 Java Console 的存储池属性下公开了此选项。选择单击存储池上的“WORM Storage”以启用此功能。
