Depending on the license, the space for the entire VM might be required during restore operation and seems there's not enough space in this case.

How can I determine if Veeam is trying to use SnapRestore or FlexClone? I have added test-licenses for both in my NetApp-Cluster.
As far as I understand, FlexClone should need much less space compared to SnapRestore.

The license used to clone the volume (FlexClone и SnapRestore) can be seen in the job log file.

you mean in Job.<backupjob-name>.Backup.log?

I can not find the word "flexclone" but I see e.g. this:
Code: Select all
[21.12.2016 00:31:11] <01> Error       bei Veeam.Backup.SanPlugin.NetAppLib.CNaHostApiImpl.SnapRestore(LogLevels logLevel, CNaConnection connection, String srcFile, String dstFile, String snapshotName)
[21.12.2016 00:31:11] <01> Error       bei Veeam.Backup.SanPlugin.NetAppLib.CNaVServerClient.SnapRestoreFileAsync(String srcFile, String dstFile, String snapshotName)
[21.12.2016 00:31:11] <01> Error       bei Veeam.Backup.SanPlugin.NetAppLib.CNaClientUtils.SnapRestoreFileSync(INaClient client, String srcFile, String dstFile, String snapshotName)
[21.12.2016 00:31:11] <01> Error       bei Veeam.Backup.SanPlugin.NetApp.CNetAppLunCloneCreator.CreateSnapRestoreCloneForVServer(CNaVServerClient vServerClient, String lunPath, String lunClonePath, String snapshotName)


Does this mean it is only trying SnapRestore and not FlexClone?

Yes, this means SnapRestore is being used. Please review this section for NetApp storage snapshots requirements and limitations.

I had to do a "Rescan Storage" so that Veeam found the newly added FlexClone license! :idea:

Does Veeam rescan storage automatically from time to time?

Yes, automatic discovery that collects this kind of information runs every 7 days.

Hi Foggy,

looking at the System Requirements https://helpcenter.veeam.com/docs/backup/vsphere/system_requirements.html?ver=95, Ontap 9.1 is not supported.
Now we've got a FAS2650 as new backup destination (SnapVault target) - but they only ship with Ontap 9.1+
Do you (or anyone else here) know if 9.1 works despite not being officially supported yet?
Or do you know when it will be supported?

Thanks a lot & greetings from Germany!

Hi DerOest,
I talked the last days to Christian Furchert, NetApp SE from office Hamburg.
We discovered a critical bug inside of Ontap 9.1. Please talk to your local NetApp SE
that can help to understand if this bug will hit you too. He can contact Christian for
more details on this.

While this bug is existing I could imagine we cannot support 9.1 until they
released a patch for this. We forwarded this issue already to our QA.

Kind regards und ein fröhliches Moin Moin aus Norddeutschland ;)
Marco

P.S. It's not a bug in combination with Veeam it seems to be a general problem
with one OS function we use intensively.

Hi Patrick,

BfSS using clones in the NetApp system and it seems that one clone function produces timeout for production systems.

I don't know if this happens in this special setup or maybe happens in all systems. NetApp R&D is working on this issue.

BfSS = Backup from Storage Snapshot?
Please post any updates as soon as you hear back from NetApp about this issue!

Ontap 9.1P1 fixed some issues, not sure if the one Marco talks about is one of them.
Has anyone heard anything regarding this?
