Sample error from a failed client backup log file: avtar Info <7694>: Server(xxxxxx.xxxxx.com) not responding (possible network congestion?) (300 seconds) avtar Error <5775>: Internal Error: backtree: bad response 4c8d1d4a37a917cd76137c9afd63a4de44b8b328 74 ADD_HASH_DATA=2 serial=74 seq=0 flags=R:N:0 kind=9 rsp=MSG_ERR_INVALID_PARAMETERS avtar Info <5726>: Aborting backup due to error (3:EXC_HFSERROR) avtar FATAL <5399>: Internal error, aborting avtar Info <9772>: Starting graceful (staged) termination, error reported in nbackmain (wrap-up stage)
There is a conflict with the information stored in the file and hash caches on the client and the related objects stored on the Avamar grid.
Remove the file and hash caches from the var directory on the client (f_cache.dat and p_cache.dat). Re-run the backup to Data Domain. The backup should now be successful.
