I don't have knowledge of Netapp NDMP, but I have EMC NDMP and I created virtual file systems. I have a VFS name which points to a real file system on the EMC.
I have one large partition and I created 8 virtual file system from it. I backup each VFS one at a time. -----Original Message----- From: ADSM: Dist Stor Manager [mailto:ads...@vm.marist.edu] On Behalf Of Mueller, Ken Sent: Tuesday, June 16, 2009 10:06 AM To: ADSM-L@VM.MARIST.EDU Subject: NDMP backup of non-qtree data We have an IBM N-Series 6040 (a thinly veiled NetApp 3140) that amoung other things contains several large volumes (2TB, 35 million files). These volumes have qtrees defined for the larger top-level directories. There are numerous other small top-level directories that are not in qtrees. We are running TSM 5.5.2.0 and using the Filer->TSM->Library method of NDMP backup (storing the backups in TSM native storage pools). It is not practical to backup the entire volume in one shot, but backing up the individual qtrees via BACKUP NODE is manageable. The problem that I have is how to specify backing up the non-qtree portion of the volume. The NetApp commands use a trailing dash after the volume name to indicate non-qtree data (ie: /vol/xyz/- ) however BACKUP NODE complains of an invalid parameter when I use that convention. I tried setting up a virtualfsmapping with the trailing dash and it is accepted for the mapping, however the subsequent BACKUP NODE process fails after it starts with an ANR9999D catchall: "Error beginning NDMP backup - illegal arguements.Check that the filespace/path '/vol/xyz/-' exists." Anybody backing up these filers at the qtree level? How do you handle the non-qtree data? We're new to the whole NDMP world - seems a few steps back from what TSM can do natively. Any sage advice is welcome! -Ken Mueller
