best backup for netapps
by Constantin Bogomolnyi 17 May '05

17 May '05

Hello, I'm wondering what is the best backup system for saving big netapps we have tried alot of solutions , but we finished by running 3 sets of netapp in snapmirror so A(master) replicates to B and C (slaves) all have now raid_dp enabled and spare around . So we have realtime B and C backups (we may cluster A and B) . But as its quite expensive "backup" i'm looking for some classic backup with tapes for example but i know from the past that tapes can be big pain to manage (specialy as we have around 2.5T of data on A) Anybody have some "tape backup" that realy works ? sub question : anybody have tried to attach a cheap ide raid shelf to scsi port of the netapp and use it as backup ? today its cheap to have 14x300 gig ide disk array with scsi port , so it could be better than tapes if its directly attached to the netapp , nan ? Best regards cb

Probably the best question is what exactly do you want these backups for? To be able to restore files people mistakenly delete/corrupt? For full-on disaster recovery? For long-term archiving? I think for the first one, various online or near-offline solutions like you've mentioned (ndmp to another server, etc) are probably fine, but then you could probably do just as well by just relying on snapshots and keep it simple. My personal opinion, which others might disagree with, is that for disaster recovery and *especially* for long-term archiving, you really need good offline storage like tapes. Something you can have shipped to a storage facility buried in a mountain somewhere. With enough money you could have multiple netapps around the country/world with snapmirror or somesuch replicating between them, which is great for DR too, but in the end I'm just not comfortable without something offline to fall back on. Imo the best solution is good backup software and a large automated tape library, but it's not going to be cheap. Even just the tapes can be a huge expense. We're still doing backups over NFS here, largely because when we tried doing NDMP a few years ago it just did not seem ready for prime time, we had too many problems. I'm very much interested in trying NDMP again though, as backing up over NFS is not the most efficient solution. I admit though, I've been in this business a long time and I'm a bit old-fashioned. Other people might be more comfortable than I am with relying entirely on hard drives for disaster recovery. -- Michael W.

RE: Snapmirror and locked files
by Umerov, Mark 12 May '05

12 May '05

As I understand it, when the block level transfer of the blocks that changed between last transfer and the time the new snapshot was taken on source is completed, Netapp makes this just transferred snapshot on the target the active file system and removes previous snapshot from the source - the target at that point is synchronized with the source at the time of the last snapshot. When the snapshot on target volume becomes the active file system, what happens to files that reside on data blocks that changed in case these files happen to be locked by clients? Does the question make sense? If it does not make any sense, let me try to ask it differently... Unlike typical NFS, when CIFS clients read the file, the file is actually locked until read operation completes. In other words, other processes cannot update the file while the file is being read. What happens in case of Netapp if CIFS clients read the file from the snapmirrored volume and the snapmirror transfer completes *while* the file is being read? thanks again, Mark -----Original Message----- From: Eric Kimminau [mailto:ekimminau@rainfinity.com] Sent: Wednesday, May 11, 2005 12:40 PM To: Umerov, Mark Cc: toasters(a)mathworks.com Subject: RE: Snapmirror and locked files Hi! I know that snapmirror is a block level solution, which, to my knowledge, has no real knowledge of the files using those blocks. Therefore I don't believe that it has no knowledge of file related locks. Then again I could be completely wrong. I would be very interested in hearing if you hear anything other that what I have below. From the iSCSI best practices paper: http://www.netapp.com/tech_library/3250.html 3.9. File Systems That Are Not Capable of Snapshots Applications that are implemented on top of file systems that are not capable of Snapshots, such as NTFS, represent the simplest scenario from a backup and recovery perspective. When backing up these applications, applications must be first quiesced, or taken offline, in order to avoid open files or files changing during the backup operation. Then, file system caches must be first committed before the backup operation commences. The application remains quiesced, or offline, until the backup is completed, at which point normal application operation can resume. This can result in a significant period of unavailability for the application. Some applications have a built-in hot backup mode, allowing a backup to occur while the application operates at a reduced efficiency and often, limited capabilities. This type of mode is typical in messaging and database applications such as Microsoft Exchange and OracleR. It will result in higher overall application availability than not using hot backup mode. However, it can potentially still result in a long interval of reduced efficiency and limited performance. One final alternative is to use an open file manager from a backup software vendor. These applications are designed to handle backup operations on files that are still locked by an application. They work well for simple applications, such as home directories and shared documents. However, they should be avoided with complex applications, such as messaging applications or databases. ================================================================= This of course assumes that snapmirror does not use the SecureShare methodology described in this paper which handles multi-protocol opportunistic locks but I don't know if snapmirror interacts in any way: http://66.102.7.104/search?q=cache:QtaPZkw0OCwJ:www.nluug.nl/events/vj99 /papers/pawlowski.ps+snapmirror+locked+files&hl=en&client=firefox-a Data integrity A thorny problem in the multiprotocol file access space is managing shared access to data in the face ofrestrictions imposed by client locking. The technology in Network Appliance filers that accomplishes this is called SecureShare, and is described in [Borr98]. SecureShare enables UNIX and Windows based applications to concurrently access and update sharedfiles, with the integrity and cache coherency of the shared data being protected by system-enforced locking and file-open semantics. The locking semantics between Windows NT and UNIX differsignificantly. Heuristics control simultaneous access to a file by both UNIX and Windows NT. Simultaneous access in a multiprotocol environment might compromise the data integrity of a file(when locked against unwanted modification by other clients) if not properly managed. UNIX clients have rather lax standards of locking compared to the more restrictive lock semantics of Windows NT. SecureShare also implements a multiprotocol extrapolation of the Windows networking performanceoptimization known as "opportunistic locks" (oplocks). Oplocks allow a Windows NT client to aggressively cache data and lock state in the absence of sharing. A Windows NT server will extend anoplock to a Windows NT client when no other client is sharing a file. When another client attempts access to a file on which an oplock is held, a Winndows NT server will "break the oplock" forcing allmodified data and lock state back to the server, and the server will then negotiate file access between clients engaged in data sharing. The SecureShare implementation of oplocks provides Windows-basedapplications the performance benefits of aggressive client-side caching and the assurance that the same "oplock break" protocol occurs in the event a UNIX-based application attempts to access an oplockedfile. ---------1---------2---------3---------4---------5---------6---------7 Eric Kimminau Email: ekimminau(a)rainfinity.com Senior Sales Engineer Office:248.766.9921 Rainfinity Fax: 248.393.8037 www.rainfinity.com ________________________________ From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Umerov, Mark Sent: Wednesday, May 11, 2005 2:58 PM To: toasters(a)mathworks.com Subject: Snapmirror and locked files greetings, Does Netapp allow locking of files on snapmirrored (read-only) volumes?

We've just added DS14mkII shelves on the fly. The only catch for us was using ESH2 modules, you have to have the right version of ontap, or it panics the filer when you open the loop. And yes, once you have the propper requirements it's as simple as flipping the terminator. The drives are seen in 30 seconds or so.

I'm curious how long it'll take for each FC controller loop to "discover" all the drives. Thanks for your suggestion. -Rob

adding new DS14mkII shelves
by Robert K. Borowicz 11 May '05

11 May '05

I'm adding 8 DS14mkII shelves on Sunday morning. The new FC controllers are already in the Filer (FAS940 running DOT 6.5.4) and blinking away. I also slid the 8 trays in (very carefully) over the past 2 weeks and cabled the copper interconnects up in-to-out between shelves this afternoon. Sunday morning we'll shut the Oracle DB's down and do the following: 1. Run the Fiber cable between the FC controller A/B ports and the Fiber based DS14 shelves. (we installed 2 and are planning on putting 4 each shelves per FC controller) 2. Run the "storage enable adapter n" command. 3. Flip the Terminator switch on the Fiber IN ports of each of the 4 ports across the two Fiber based shelves. My question is: Does it matter in which order I flip the terminator switch and/or run the "storage" command? Should I flip the Terminator switch off and *then* issue the "storage" command? I'm thinking Terminator switch last.... TIA -Rob

RE: New certification path (NACP/NACA)
by Hill, Aaron 10 May '05

For the most part, I must agree. My only gripe is that the requirements have been relaxed significantly; I sat the FAS900 hardware and ONTAP Admin exams when they were still needed for the NACA. Then I sat the ONTAP Advanced and the 3 NACP exams for my NACE. Now I find you only need 4 exams to get to NACE ...... hmmmm. The exams were no nonsense, I either knew all my stuff and passed, or didn't know it all and failed. This happened with the Data Protection exam when the snaplock stuff was introduced in 6.5. So I had to update myself to pass the exam the second time. This was acceptable. There were no long-winded questions that tried to baffle me intentionally like many other vendor exams I have taken. NetApp ask you a question straight up and then you answer it, no unnecessary ambiguity that I could detect. Almost all the exam content is found in the course material as mentioned. It is also very wise to do a NOW search on the technology you are studying and basically learn and read as much as possible. The rest is memory training and as we all know, there are many tricks that can be employed to make that easier. Experience will make answering the troubleshooting questions a breeze. When I felt I lacked experience in a particular area, I read through the KB articles and found them very helpful.

File reconfigurations and upgrading to OnTAP 7
by Lance A. Brown 09 May '05

09 May '05

Greetings, Wanted to run this past y'all before actually doing it. We have a project under way to reconfigure how we are using our netapps (2 FAS940s and 2 F820s) and get thema ll upgraded to Data OnTAP 7. Our two 820s are nearly full, so upgrading them to OnTAP 7 and then getting everything into FlexVols was going to be annoying and drawn out for lack of spare disk space to create an aggregate and get the cascade of traditional volumes to FlexVols going. Instead, we are thinking of attaching a new DS14 shelf to one of our FAS940s which already has OnTAP 7 on it, copy all the data from an F820 to an aggregate built from the disks in the DS14. Reconfigure the F820 by removing old low-density disk shelves and upgrade it to Data OnTAP 7, and then move the DS14 on the FAS940 to the F820. Moving disk shelves and what not around isn't a problem. I'm familiar with that. The kink here is that we need to switch from ESH modules in the DS14 to LRCs when we move it from the FAS940 to the F820. Does anyone know if that will cause a problem? --[Lance] -- Lance A.

I fond the NetApp exams to be probably some of the best in regards to the following: 1) They do not ask questions that are on notes in the training materials. 2) The questions are all on relavent information that is contained in the training materials 3) There are 5 questions related to experience in working with the Filer This is done to help eliminate the 'paper' certifications. 4) On the above experience questions should not cause you to fail if you have studied the training material. 5) After any of the exams I've been able to go to the training material and find the answer rather easily.
