Symptoms

PowerProtect 数据保护存储设备用于通过 Transparent Snapshot Data Mover （TSDM） 解决方案保护 vSphere 环境。
虚拟机备份间歇性地执行完整级别备份，而不是计划的合成增量完整备份。
虚拟机增量备份需要 ~6 分钟才能完成，意外的完整备份需要 ~12 小时才能完成。

备份会话日志显示为备份会话请求了快照数据移动器 （SDM） 完全同步：

Cause

这是 PowerProtect 19.13 及更早版本中的已知问题。  

备份逻辑会检查虚拟机的最后 10 个拷贝。
这 10 个拷贝按创建时间和最近的 dataTargetId 进行排序。
将 dataTargetId 与正在运行的保护策略阶段 dataTargetId 进行比较。
如果在比较过程中第一个检索到的 dataTargetIds 不相同，则不考虑拷贝（未找到拷贝）。  
在某些情况下，返回的第一个拷贝是有效的复制拷贝 （Replica dataTargetId），它与当前拷贝目标 （Target dataTargetId） 不同。

Resolution

此问题已在 PowerProtect 19.14 （PPDM-231108） 中得到解决。如果需要，请联系戴尔技术支持以了解更多详细信息。

作为比较，以前的合成完整备份显示它检索了以前的拷贝：
