SnapCenter Exchange 备份失败，出现"VSS_E_HOLD_WRITES_TIMEOUT"错误

适用于

• 适用于 Microsoft Exchange Server 的 SnapCenter 插件 (SCE)
• VSS 快照创建

问题

• SnapCenter 的 Exchange 备份作业失败，出现以下部分或全部错误：

Activity 'Creating Backup' failed with error: Failed to create VSS snapshot [Error Code: -2147212524] [VSS_E_HOLD_WRITES_TIMEOUT] [Error Code: -2147212524] [VSS_E_HOLD_WRITES_TIMEOUT]

Activity 'Renaming VSS Snapshot' failed with error: Skip renaming snapshot

Activity 'Creating Snapshot copy for log backup' failed with error: Skip creating snapshot on log LUN

Activity 'Registering Backup and Applying Retention' failed with error: Failed to register backup metadata, backup metadata is null or empty

• 当备份失败时，一个或多个 Exchange 服务器上的 Exchange Writer 可能会进入失败状态。
• 此问题也可能在将 SnapCenter 和 Exchange 插件从 5.x 升级到 6.x 之后开始出现。
