Summary: Backup for NAS Asset DNAS_share_name$ promoted to GEN0.; 
Details: The backup for NAS asset was promoted to GEN0 as the agent could not find previous backup meta data.;

Cause

備份會從 SYNTHETIC FULL 升級為 FULL （GEN0）， 因為 PowerProtect Data Manager 代理程式無法找到先前備份的中繼資料。此問題會在 PowerProtect Data Manager 19.19 版中推出，通常會在 changelist metadata 缺失或無法訪問。

Resolution

要解決此問題：

  • 升級至 PowerProtect Data Manager 19.22 版，可解決中繼資料處理問題。
