No further development of OnCommand Host? Or no plans to include single file restore? I don't understand why NetApp have two slightly different products doing similar things, each with important missing pieces of functionality or usability.

I don't understand why having more than 250 qtrees would cause too many snapshots on either side, at least after the initial baseline - could you explain? Thanks, Richard

rmharwood · ‎2012-04-19

Yes but if you need to restore from those backups you need to have them somewhere else, obviously, either copied to tape or to a snapvault secondary.

rmharwood · ‎2012-04-19

Yes, a script would work. We work around this by archiving to secondary every day and only keeping one day's worth on the primary. The restores are a little more complex but the amount of space used (/wasted) on logs is gone. I have never understood the necessity to keep all of the logs AND keep all of the previous logs in snapshots. I agree that utm should still be possible by using just snapshots.

rmharwood · ‎2012-04-19

The logs get flushed according to the snapshot retention period, but SME seems to ignore the "point in time" / "up to the minute" retention. I don't think there is a workaround other than manually removing the log files from the appropriate snapinfo folder. Richard

Just caught this thread. I opened a support case on this exact issue a couple of months back and it was flagged as a known bug with ID 554340 (not publicly visible). The fix is due in the "next release" but I was told this is not scheduled until Q3. Richard

rmharwood · ‎2012-04-18

What I don't understand is, SME takes and keeps snapshots of the logs LUN for the retention period so what is the point in keeping all of the logs in the active file system in addition? There doesn't seem to be a point in keeping both. I get around this by archiving (via DFM) to a secondary filer and only keeping one snapshot and one day's logs on the primary. I was also told there was a known bug (554340, not publicly visible) related to a problem with cycling out old log files. There is also the "frequent restore point" functionality, which I was never quite clear on. Richard

Right now I have each qtree listed in the dataset. If I remove all these and specify just the source volume instead, what exactly will happen??

rmharwood · ‎2012-04-16

Excellent - thank you for clearing that up. As a side note, do you have an ETA when DFM 5.0.1 will be released?

rmharwood · ‎2012-04-16

I agree with what you said. I am not sure if you can just add a volume into PM and have it watch for new qtrees though - having said that it's not something I've tested and it may work. Adai - can you comment on this?

rmharwood · ‎2012-04-16

I don't think this can be done. The dataset always has a fixed name and SMSQL will use it if one exists already, or create a new one if it doesn't. Removing the dataset should not remove any volumes so you can still access the snaps, but you can't then use SMSQL to restore from them. Richard

rmharwood · ‎2012-04-16

I'm successfully doing this with about 200 qtrees. I don't know why PM is trying to create so many snaps on the primary. What you may need to do is build the dataset gradually by adding a smaller number of qtrees at a time, waiting for conformance to complete before adding more. Cheers, Richard

I don't think enabling compression via the sis command is available until ONTAP 8.1. The commands for volume compression are under the "vol" command. I would advise you take a look at the Storage Management Guide for 8.0.2. Cheers, Richard

rmharwood · ‎2012-04-13

Actually yes. This is the main reason I switched to DFM 5 / OnCommand Core/Host in the first place. I'll see if I can go about removing it. I feel very disappointed with a lot of the recent software changes from NetApp.

rmharwood · ‎2012-04-13

We're also being affected by this - FAS3160 running 8.1RC3 and DFM 5.0. In 24 hours the httpd max has hit the limit of 1023. Any updates since last week on this?

rmharwood · ‎2012-04-04

I have found a useful trick to avoid having LUNs go offline but don't over-allocate space is to enable autogrow on the volume. This is done through the "vol autosize" command, and possibly via System Manager. The volume then can grow to accommodate the space it needs to function.

rmharwood · ‎2012-03-20

I have several volumes that only have LUNs with no snapshots and are at or almost at 100%. Make sure that your LUNs are space reserved (in other words, NOT thin provisioned). Double check that you have no snapshots in the volume. Richard

rmharwood · ‎2012-03-16

In short, you can't. The Snap Manager products were not (well) designed to cope with any offline backups. I believe, however, that the Snap Protect products have some integration with tape backups. With Exchange you can restore the entire LUN from tape, mount up the LUN using snapdrive and then either use SMBR to read the EDB file or possibly mount it as a recovery/restore database. I don't know much about MSSQL but I'm guessing you can do something similar to that. We use NDMP to send LUNs to tape here, but generally only for DR purposes, not for granular restores. Richard

rmharwood · ‎2012-03-16

Well, it's not common practice to have a LUN in the same location as other (NAS) files.

rmharwood · ‎2012-03-16

So, you have a snapshot named "sep1011" with those files inside.

rmharwood · ‎2012-03-16

Folders beneath the ~snapshot folder are the different snapshots on the volume containing the CIFS share. Perhaps you have a snapshot named "sep1011". The ~snapshot folder does not contain anything other than snapshots.

rmharwood · ‎2012-03-16

Contents of snapshots are always read-only. If you don't want those files in there, the only option you have is to delete the snapshot that they're in. You will also be removing access to any other files in the snapshot, unless you copy them somewhere else first. Richard

rmharwood · ‎2012-03-16

If this is between two Netapp volumes you can use ndmpcopy on the filer. Richard

I'm either missing something or I'm misinformed on something. I've read a few similar posts but nothing seems to be quite on the mark. SME backups on Exchange 2010 are completing successfully but copies of log files are still being retained in the sme_snapinfo folder on the logs LUN for the duration. I have no interest in keeping log files in the sme_snapinfo folder for longer than one day: I don't need a point-in-time recovery beyond that. Here is the command that is getting run from task scheduler (every night): smejoblauncher.exe new-backup -Server 'LUEMSMAIL03' -ManagementGroup 'Standard' -RetainDays 8 -RetainUtmDays 0 -StorageGroup 'FS03','FS01' -UseMountPoint -MountPointDir 'C:\Program Files\NetApp\SnapManager for Exchange\SnapMgrMountPoint' -RemoteAdditionalCopyBackup $False So.. should the logs be getting purged from the sme_snapinfo folders? If so, why are they not? Thanks in advance for any help on this. Cheers, Richard

rmharwood · ‎2012-01-27

Not sure if I've seen that specific problem, but definitely similar ones. All I can suggest is that you have the latest Snapdrive installed as this is the service that communicates with DFM. Richard
