NDMP very slow - would this help?
Ques : If remote NDMP (NetApp) is slow then direct NDMP would be equally slow? Assuming that there are no netwrok or media server perfromance issues.
Currently running remote NDMP to disk staging becuse of the unnatural slowness of NetApp NDMP. Its that slow it takes days to backup and runs at a spped that would shoeshine a tape drive to death ( ~20MB/s). Found that using smtape type of NDMP backup as waste of time becasue was eithr about the same time or longer. Given these are single large volumes (~10 TB with about 75 millions files) it doesn't matter if they are multiplexed or.
My guess would be they would also run at ~20MB/s if the tape drives were directly connected (directNDMP)
Other vFiler backups on the same controllers seem to run OK casue they are much smaller, this tells me its not a network issue but usuall problem of NetApp being slow.
Backup environment : NBU 18.104.22.168 W2k8 x64 servers.
