Symptoms

NetWorker VMware 保护集成配置了 vProxy Appliance。备份始终失败,表明 vProxy 无法在 Data Domain (DD) 上打开以前的备份。

备份会话日志显示以下错误:
YYYY/MM/DD HH:MM:SS ERROR: [@(#) Build number: ##] Failed to open Backup Descriptor file "/[MTREE2_NAME]/[DEVICE_NAME]/52/00/c2b12b8b-00000006-9f9924fb-5b9924fb-12625000-0e1bbb56/BackupDescriptor.json".
YYYY/MM/DD HH:MM:SS ERROR: [@(#) Build number: ##] Unable to open previous backup.

Cause

将 vProxy 备份写入的 DDBoost 设备已更改。出现该错误是因为新设备上不存在以前的增量备份。

Resolution

此行为按设计正常工作。

如果 Data Domain 设备已更改,请在策略上设置计划覆盖,并运行到新设备的新级别完整备份。
