Hi Tommaso, The backup command I'm using (dsmc i /Airwarder -snapdiff -snapdiffhttps -diffsnapshotname="daily.*" -diffsnapshot=latest -useexistingbase -optfile=dsm_netapp.opt) includes the "useexistingbase" statement. Based on my understanding of the documentation, this means that the S.P. client will not trigger the creation of a new snapshot on the Netapp device, but instead, make use of a snapshot that had been created previously by some internal mechanism of the Netapp. Therefore, it seems very unlikely that any process still has a grip on any of the files being part of this snapshot ... My humble opinion only of course, I'm waiting on others fellow members of this list feedback !
In addition to this, I would like to avoid the use of any exclude statement during the backup : I doubt that any of my customers would be very happy to hear that I'm not able to restore some of his precious files because the Spectrum Protect client had limitations ... Such issues never aroused with NDMP-based backups ! Cheers.

Perhaps you can solve by inserting the appropiate rules in incl.excl file to skip them. -----Messaggio originale----- Da: ADSM: Dist Stor Manager [mailto:ADSM-L@VM.MARIST.EDU] Per conto di PAC Brion Arnaud Inviato: martedì 18 settembre 2018 12:21 A: ADSM-L@VM.MARIST.EDU Oggetto: [ADSM-L] Netapp snapdiff issues having TSM client on a Linux machine, making use of NFS mounts Hi All, Following to IBM's decision to withdraw the web GUI in the latest versions of their clients (thus making NDMP hardly usable), as well as to the renewal of our NAS infrastructure (now using Netapp), I'm trying to implement netapp snapdiffs in our shop. So far we succeeded in defining necessary user and roles on the Netapp, as well as to setup the TSM client in order to interact with our filer, but I'm now facing an issue where some files cannot be backed up, apparently due to access rights.
