问题

SnapVault (XDP) 的“旋转阶段”传输到启用重复数据删除的目标位置、 CommVault Simpana /SnapProtect 可能会错误地使用临时的“ SnapMirrorSe* ”名称对数据进行编目。由于 Resolve Simpana / SnapProtect 无法定位这些快照以执行包括磁带备份、恢复、级联复制、计划索引和修剪在内的操作。

SnapProtect /Simpana 无法在启用重复数据删除的 Vault (XDP) 目标上执行删除、备份到磁带、进一步复制(级联)快照。
CommVault Media Agent 日志( CVMA.* )显示尝试删除名称以字符串 "SnapMirrorSE" 开头的快照

在文件管理器端、在 Vault 目标上的 MGWD 日志中观察到失败的快照删除尝试:
