Re: Netapp snapdiff issues having TSM client on a Linux machine, making use of NFS mounts
Hi Efim and All who helped Quick update on this : it appeared that some export policy rule (i.e." -superuser sys" ) had not been properly set on our Netapp, thus refraining TSM client to reach some files. Once this corrected, I was able to get successful snapshot backups done. @Efim : thanks for your advice, I'll take it in consideration ! Just have to discuss with our storage team what exactly they are expecting from me ;-) Cheers.

Del, Thanks for your clarifications which are perfectly making sense.

Re: Netapp snapdiff issues having TSM client on a Linux machine, making use of NFS mounts
Brion: Here at Cornell, we have a TSM client on a Linux system backing up NFS shares via NFS mounts and snapdiff differentials - and have been doing so for years. First, the gory details: - For TSM TSM Client Version 7, Release 1, Level 6.0 (*red faced, thought I had upgraded to SP 8.1.2.0 months ago*) Running on CentOS Linux release 7.5.1804 (kernel 3.10.0-862.2.3.el7.x86_64) Accessing TSM Server for Linux Version 7, Release 1, Level 7.200 - For NetApp Filer Version Information: NetApp Release 9.3P6 We aren’t seeing your issue, and I suspect I know why. We are telling the TSM client to create its own snapshots - and not use the snapshots being created hourly (or daily or weekly even) by the team managing the Netapp - said snapshots being equivalent to the ones you are trying to take advantage of in your backups. That is, the relevant part of the daily backup schedule looks like: Schedule Name: DAILY.INCR.NFS.SNAPDIFF Description: Daily SnapDiff Incremental Action: Incremental Subaction: Options: -snapdiff -diffsnapshot=create -snapdiffhttps During a backup, then, the following type of information is written to the dsmsched.log: 09/13/2018 00:38:08 Incremental by snapshot difference of volume '/nas-backup/vol/cit-pea1-test' 09/13/2018 00:38:10 ANS2328I Using Snapshot Differential Change Log. 09/13/2018 00:38:10 Connected to NetApp Storage Virtual Machine Management Filer Host/IP Address : ccc-cdot01.cit.cornell.edu Filer Version Information: NetApp Release 9.3P6: Thu Jun 14 20:21:25 UTC 2018 Storage VM Name : cit-sfshared05 Storage VM Host/IP Address : cit-sfshared05-backup.files.cornell.edu Storage VM Volume Style : Flex Login User : tsmbackup Transport: HTTPS 09/13/2018 00:38:10 Performing a Snapshot Differential Backup of volume '/nas-backup/vol/cit-pea1-test' 09/13/2018 00:38:10 Creating Diff Snapshot. 09/13/2018 00:38:10 Using Base Snapshot 'TSM_SANT5B9759FC1AB6_CIT_PEA1_TEST_VOL' with timestamp 09/11/2018 06:00:28 09/13/2018 00:38:10 Using Diff Snapshot 'TSM_SANT5B99E9B24F814_CIT_PEA1_TEST_VOL' with timestamp 09/13/2018 04:38:10 Then, on the next backup (48 hours later thanks to a large amount of data to backup on 9/13), the Diff Snapshot becomes the base: 09/15/2018 01:29:22 ANS2328I Using Snapshot Differential Change Log. 09/15/2018 01:29:22 Connected to NetApp Storage Virtual Machine Management Filer Host/IP Address : ccc-cdot01.cit.cornell.edu Filer Version Information: NetApp Release 9.3P6: Thu Jun 14 20:21:25 UTC 2018 Storage VM Name : cit-sfshared05 Storage VM Host/IP Address : cit-sfshared05-backup.files.cornell.edu Storage VM Volume Style : Flex Login User : tsmbackup Transport: HTTPS 09/15/2018 01:29:22 Performing a Snapshot Differential Backup of volume '/nas-backup/vol/cit-pea1-test' 09/15/2018 01:29:22 Creating Diff Snapshot. 09/15/2018 01:29:22 Using Base Snapshot 'TSM_SANT5B99E9B24F814_CIT_PEA1_TEST_VOL' with timestamp 09/13/2018 04:38:10 09/15/2018 01:29:22 Using Diff Snapshot 'TSM_SANT5B9C98B1A15B2_CIT_PEA1_TEST_VOL' with timestamp 09/15/2018 05:29:21 I think that consistency is what is missing in your approach - I suspect that there are intervening snapshots with information about files that have been deleted or changed that are not part of what the TSM client is seeing. I will add that our NetApp team is very happy with this approach. The TSM client has been very efficient in its management of the snapshots, and in those rare cases when it doesn’t, the snapshots are easy to identify and clean up.

Re: Netapp snapdiff issues having TSM client on a Linux machine, making use of NFS mounts
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.

Re: Netapp snapdiff issues having TSM client on a Linux machine, making use of NFS mounts
Hi Del, Thanks for the information, which I got as well thru other channels (IBM support), but there's still the limitation that this GUI will be usable only once logged on the machine hosting the Spectrum Protect client. This means that I will be forced to grant some of my colleagues (which were previously doing the restores on their own) specific logging rights on that machine. Was not the case before ... Cheers.
