Hi, I have a problem backing up exchange 5.5 with arcserve 6.6. I have all the client and exchange agents installed but keep getting the followint error: E8602 "failed to read from database. EC=DBagent Error - (301). Exchange Server Error. HrBackupPrepare Failed. Check DBagent Activity Log. E8604 "Failed to start backup. EC=DBAgent Error--()"error status in named pipe" I am not getting any help from CA at all. Infact, I keep tellig them that all thier solutions do not help but they keep giving me the same solution over and over again. Has anyone else come across this problem before? I can do a brick level backup but in the long run I want to also back up the database for disaster recovery. I would appreciate any kind of help. Thank you, Lotech.
