Re: Budtool / backup sw Mailing-List??

As far as I can tell (from www.liszt.com), there does not exist a list like this, so I've just created a new majordomo mailing list in response to these requests. It seems like folks are interested in both NetApp and Enterprise backup issues so I've tried to name the list accordingly (and in the spirit of BIG-LAN). Details follow: To subscribe: bigbackup-request(a)ccs.neu.edu To send to the list: bigbackup(a)ccs.neu.edu I'm hoping this will be a good place to discuss technical issues around the backup of large amounts of data from a {Netapp, Auspex, EMC...} box via {Budtool, Legato, QuickRestore...} etc. Other enterprise-wide backup issues are also welcome. I've set this list to be non-moderated, but closed to postings from non-members. Should the signal-to-noise ratio get too high, I'll flip it to moderated and take it from there. I've also disabled the "who" command so the addresses of the members will not be reaped enmasse by VARs (though I am not hiding the addresses of individual posters). In general, I'd appreciate it if marketing folks could also play nice. Hope this is useful, please feel free to send any comments or questions about this list directly to me. Respectfully, David N.

Re: Budtool and NetWorker

Jay Orr <orrjl(a)stl.nexen.com> writes: > Has anyone that uses Budtool to backup gotten any details about the option > to upgrade to NetWorker? I spoke to our local Legato rep about this right before Y2k and he was a wealth of "don't know yet" answers. He was sure they would have an "upgrade" program for exisiting customers, but not for a while. Apparently they are going to avoid an EOL for Budtool until the end of '00 and still sell it as a separate product until then. In the meantime, they are supposedly integrating Budtool into their standard Legato framework. He made it sound like Budtool would be a module as part of their usual stuff. It sounds like the folks in the field haven't heard yet because they haven't figured it out at the Legato homebase either. He suggested I contact his inside sales person, but I have not done that. Summary: nice soothing noises, but no real information Respectfully, David N. Blank-Edelman Director of Technology College of Computer Science Northeastern University

RE: checksum_blocks vol option?
by Mohler,Anissa 11 Jan '00

11 Jan '00

The following is an excerpt from the 5.3.4R2 Start Here Guide - page 29. You can download the PDF file from the NOW site in the software download section. ========== start excerpt ============ Starting with 5.3.2, Data ONTAP checks the consistency of parity when performing disk scrubbing. If it detects parity inconsistency, the following events take place: - A message is logged to /etc/messages indicating that there is parity inconsistency. When you see this message, it is important to call Technical Support for help in determining the root cause of the problem. - Data ONTAP enables block checksums to ensure data integrity. When checksums are enabled, there is some performance degradation. If checksums are incorrect, Data ONTAP generates an error message similar to this one: Checksum mismatch on disk 4.0, block 436964 A file named /etc/crash/parity_inconsistencies is created. It contains information about disk scrubbing, which helps Technical Support solve the parity inconsistency problem. ========= end excerpt =============== I hope this helps.

NetApp and RDBMS (Oracle/Sybase)

Dear all... we are researching the purchase of a Network Applicance F740, for which one of the primary uses would be service of a commercial RDBMS (either Sybase or Oracle). Until I looked into this last week, I was unaware this was possible and officially supported... I'm very enthusiastic about the possibility - so far, feedback on this has been generally positive. I'm looking for as many people as possible to help validate... Thomas -- Thomas Leavitt -- thomas.leavitt(a)clickrebates.com; 408-591-3342 Co-Founder/COO, ClickRebates.Com, Inc.

Re: Backing up with SAMS Alexandria
by Mark D Fowle 11 Jan '00

11 Jan '00

Quentin, We are also using Alexandria (although we wish we had something else) - We discovered that direct NFS mounts to the Alexandria server to the Netapps works best. We backup each top level directory and its associated sub directories and it seems to work fine.

Fowle/0V/Caterpillar) Subject: Backing up with SAMS Alexandria Retain Until: 02/09/2000 Retention Category: G90 - Information and Reports We are trying to backup 12 NetApp Filers using Alexandria. I was curious who else is trying to backup Filers with Alexandria and how they have implemented their solution. We have had a lot of troubles with doing Filer backups with Alexandria, especially with the Alexandria database.

Re: NFS UDP xfer size

On Mon 10 Jan, 2000, Paul Taylor <ptaylor(a)connectria.com> wrote: >options nfs.udp.xfersize <value> Don't forget that even if you set this, you've going to have to unmount and remount the filesystem in question. Previous discussions (April 1999 - check the archives) have covered this pretty well: http://teaparty.mathworks.com:1999/toasters/2648.html probably sums it up best. But other mentions of 'nfs.udp.xfersize' in there are worth reading too. It goes without saying that you should check release notes too, to be sure that there are no bugs at the root of the question you had nor with the things talked about in the above mail from the archive.

Log bugs if it doesn't work. 8) Remember to check all the settings on the clients: on the interfaces, the stack and the higher-level protocol as appropriate. Suns, by way of example, have oodles of things to set, as came up recently. The jury's still out on how much you can do on the client, but I'd say it's leaning toward 'quite a bit'. Also use whatever network tools you have, managed switches etc. to check for the usual problems with performance: collisions, duplex confusions, high broadcasts, other major traffic sources on the same or intervening segments. If you overlook something in this area then you might find tweaking the nfs.udp.xfersize is a retrograde change, against expectation. Then again, maybe I'm explaining how to suck eggs here. > Paul Taylor > Sr. Systems Engineer > Connectria > 215-841-5540 > >-- End of excerpt from Paul Taylor -- -Mark ... an Englishman in London ...
