RE: Legato Backups.
by Mike Sphar 20 Sep '02

20 Sep '02

We've been backing up 3 of our filers over NFS for 4-5 years now with no significant problems. We've done lots of restores as well. The only real caveat would be that NT ACL's are not preserved, but since all our qtrees are UNIX, that's not a problem for us. We tried a demo of the NDMP Legato solution shortly after it was made available, but we found it flaky and unreliable, so we went back to NFS. I'd imagine it's much improved now over what it was then. -- Mike Sphar - Sr Systems Administrator - Remedy Corporation -----Original Message----- From: Peter Bryant [mailto:PBryant@burallplastec.com] Sent: Friday, September 20, 2002 9:47 AM To: 'Paul J.

RE: Moving data from NT to NetApp painfully slow
by Haber, David J. 20 Sep '02

20 Sep '02

We've moved about 500G to the filer from our file servers using SecureCopy. Have you checked the port speed and duplex settings on your servers and switches and filer. We have found that if they don't match you will have excruciating performance. -----Original Message----- From: Friedrich, Bernhard [mailto:Bernhard.Friedrich@med.uni-heidelberg.de] Sent: Friday, September 20, 2002 9:29 AM To: 'toasters(a)mathworks.com' Subject: Moving data from NT to NetApp painfully slow Hi Toasters, we're in the process of consolidating NT file services on a NetApp Filer. We have an F810 where we want to store all our user's data which is now spread across multiple servers, some of which are close to being maxed out. We now have the problem of moving all the data while we're still servicing our users - we're on 24/7 here. We found that copying the data to the filer is painfully slow; we're suspecting that NT ACLs might be the culprit. We've tried robocopy, secure copy and xxcopy to no avail - moving a small part of the total data took 15 hours. Anybody out there willing to share their experiences with moving several hundreds of GB across the network? We need to keep NT permissions, obviously. On the mailing list I saw references to Fastlane and Aelita's SCW - any experience with those or other 3rd party products?

RE: Legato Backups.
by Caven, Marilyn 19 Sep '02

For three years I did just that, back up 7 Netapp filers by way of nfs mounts, using Networker 6.0.1 build 174 on a Solaris 2.8 OS, two E250 Servers. and using two L1000 tape library w/4 DLT7000 drives each. The Networker servers have a Gigabit connection to the network, (2) 296MHz CPU's and 768mb memory and I'm backing up 1.5 TB of Netapp data. We recently went to LTO tapes, one Sun 220R server w/ (1) 450MHz, 1GB memory, gig card for the Solaris side and a NT box to map mount our CIFS only server, both connected to a single Dell Powervault 60 slot tape library. One of the reasons we went this way was because we were already invested in Legato Networker software licenses for 60 clients and 2 servers. I do weekly full backups of the 1.5 TB Netapp data and another half TB of Solaris and NT clients and daily incrementals. So my final statement is, performance is not an issue for me.

Dear Toasters, I was wondering if any of you guys were using Legato for backing up your NetApps. I currently have 2 filers that i am backing up to a Legato server running Solaris 2.8 over NFS. I mount the NetApp volumes onto the legato server and then backup those mount points. I am not sure this is the best thing to do in terms of performance. Is there an alternate, easier solution.

NFS security concerns
by Allen, Pat 19 Sep '02

19 Sep '02

Hi all, I hope that this isn't too obvious a question but here goes.... I'm wondering how people are handling NFS security in environments where you have a lot of Mac OS X or Linux computer systems. For ease of administration, I would love to be able to specify that any computer within our network has read access to various qtrees. But this opens up a can of worms in that anybody with root access on their local Mac or Linux box can spoof user accounts with legitimate UID's and GID's. This essentially gives away the keys to the kingdom. The other obvious alternative is using netgroups but that would be a lot of administration as machines come and go. It's certainly better than opening up access to everybody but not a course that I'd like to take. Are there any other alternatives that I'm missing?

NAC on "Using the Linux® NFS Client with Network Appliance?"
by Quentin Fennessy 18 Sep '02

18 Sep '02

I don't recall seeing this mentioned on the toasters list. Netapp has a new (12 Aug 2002) white paper on Linux NFS client tuning, done by Chuck Lever. http://www.netapp.com/tech_library/3183.html I think you can get to this paper without NOW access. The paper is self-described as: This report provides advice for getting the best from your Linux NFS clients in an environment that includes Network Appliance filers. You'll learn what level of performance to expect from your Linux systems. You'll learn how to tune your Linux clients and diagnose performance and reliability problems. We'll recommend software levels and hardware combinations that are known to work well. Finally, you'll learn where to look for more information when faced with problems that are difficult to diagnose. Good stuff. two thumbs way up. This paper should perhaps be read while using an internal voice with a Scottish burr. -- Quentin Fennessy Quentin.Fennessy(a)amd.com Office: 512.602.3873 Cell: 512.694.7489

Re: NetApp Gripe.
by ScottUCE＠aol.com 18 Sep '02

NetApp operates no differently than other vendors -- hardware maintenance pricing ratchets up on aging systems as newer models begin to deliver in volume. However, third parties can usually provide hardware maintenance contracts for older systems that provide significant savings to the user in the range of 30-50%. As part of these contracts, spare parts and/or complete (unlicensed) "failover" filers/systems are often kept on-site; this paves the way for "mean-time-to-repair" and "availability" that are actually superior to what the manufacturers' field engineering organizations can deliver.

RE:

Hi Bruno, We ran Solaris 2.6 with ASE 12.0 for a while with the devices on our F820 and F880 but ran into some major performance issues. Mostly related to network throughput. Once we moved to 2.8 and SUN 2.0 Gigabit NICS, these problems disappeared. I am not a sybase expert, but I know we have a separate volume that we perform sybase dumps to. We ftp the dumps daily to a F820 at our Disaster Recovery site. This process works fine as long as we have bandwidth available on the WAN. We would have preferred to use Snapmirror, but that requires ASE 12.5 and a special quiesce procedure. You can find more on this at the NetApp NOW website, I think the article is a whitepaper on Sybase Disaster Recovery. If you have any more specific questions, let me know, I may be able have a chat to our Sybase Architect.
