backup exec 无法备份dag

http://social.technet.microsoft.com/Forums/en-US/exchangesvradmin/thread/1f682890-5da8-469e-a512-de59804ebd22

今天另外一个站点在备份dag时报错,

Resources specified for snapshot do not have any valid data on them. Check if files were deleted or renamed.

环境exchange 2010+backup exec 2012

后来通过如下设置解决

大致看了backup exec的kb,问题产生有如下可能:

1:没有backup exec for exchange的license,添加license即可。

2:从上次服务器重启后有修改过exchange store,vss没有aware到新的内容,解决方法:重新启动服务器,最好把mca和mdb服务器都重启

3:"Microsoft Exchange Replica writer"    在active node的exchange中是失败的状态,可通过vssadmin list writers查看,可以通过选择使用仅备从active server中备份。

4:backup exec定义的系统账号有问题。如果是从旧的exchange中迁移的话,必须新建账号并给予权限。
