restoring veritas NDMP backup with restore
by Bruce Arden 10 Apr '01

10 Apr '01

Does anyone know how to restore a Veritas NetBackup NDMP backup using restore (or ufsrestore)? Its quite easy with a single tape backup (you do a "mt -f nrst0a fsf 1; mt -f nrst0a fsr 2" to skip over the Veritas header). But after skipping the header on a second tape, the format doesn't seem to be the same as a normal dump continuation tape. - Bruce -- Bruce Arden arden(a)nortelnetworks.com Nortel Networks, London Rd, Harlow, England +44 1279 40 2877

Good to find somebody who has been carrying out some testing. We are very interested in finding out if there has been a performance hit on the filers when virus scanning is enabled ? We are in the process of getting a beta version, but any news from people who have already tested is always good.

Dear Craig, Thanks for your interest in Trend Micro's ServerProtect for Network Appliance Filer 5.3. The product is being under external beta test, and is expected to release on 4/30/01 if the test is fine. I'll keep you informed of our progress.

I did want to let you know that 1) at least one person has good things to say about your product 2) another person would like to see more info on your company's web site. If you know the right person to contact, perhaps you could get the Trend website updated with more info? But perhaps you will not be putting info on the website until the beta test is complete? I am glad to see interest in your product and I hope it is very successful!

NDMP performance
by Dianna Mullet 10 Apr '01

10 Apr '01

Is there anyone out there who backs up a filer directly to DLT via NDMP? I've seen a demo of an F740 backing up directly to a DLT 7000 and the throughput peaked at around 8MB/sec. I'd like to know actual vs. theoretical throughput for the same configuration, but with a DLT 4000. Thanks, Dianna

reducing getattr's
by kevin graham 09 Apr '01

09 Apr '01

Slightly OT, as it isn't directly netapp related, but does anyone know of a way to test if a file exists in Solaris besides a full-fledged stat() or attempting an open? I'm looking through web server stats, and I noticed I'm spending most of my nfs time doing getattrs, which I presume map back to stats that (mostly) test for existance. It strikes me that a getattr is rather painful in contrast to a lookup, but I have no idea how (or if) if the lesser can be forced. I've toyed with the idea of increasing actimeo and friends up, but am not sure of all the caveats of doing so (namely, are negative entries cached? I'm thinking along the lines of DNS's NXDOMAIN cachine semantics .. false positives would be OK, but the false negatives would be baaad). Ideas? Thanks. ..kg..

BudTool transition news
by Marion Hakanson 09 Apr '01

09 Apr '01

Folks, Dunno if it's top secret, or what, but this week I innocently (hah!) asked Legato about transferring my BudTool license to a new NetApp that may be coming in soon. Their website says host transfers are free, so what the heck? Anyway, instead of getting an answer, I got directed to my local Legato salesperson, who informed me that they've finally come to their senses and are offering a one-for-one exchange to replace our BudTool products with equivalent NetWorker products, at no cost other than putting it all back on tech-support contract. I checked, and it's not 1-April-2001. Maybe by the Mayan calendar? By my investigation so far, NetWorker-6.1 claims it will do everything our BudTool-4.6.1 does, with the exception of: (1) NDMP backup to non-NetApp tape drive. An extra-cost SnapImage option turns your Networker tape host into an NDMP tape server to provide this functionality. OK, so it's not quite 1-for-1. (2) Cloning NDMP tapes. They say that'll be along soon (I forgot to ask if I could do that with SnapImage). But one can do a second backup to offsite media to partially work around this limitation. I'm still not wild about Networker, but "Free is a very good price." Well, not counting the initial $30k investment in BudTool, anyway. So, has anyone else heard about this? I could find no mention of it (nor any previous transition programs) on their website. Regards, -- Marion Hakanson <hakanson(a)cse.ogi.edu> CSE Computing Facilities

Linux 2.4.X w/ NFSV3, Oracle, and NetApps
by Lance A. Brown 09 Apr '01

09 Apr '01

Greetings, We are successfully running Oracle 8.1.6 on RH Linux 6.2 Enterprise Edition systems with (almost) all data storage on NetApp F720 Filers. This is running over NFSv2, of course. I've just received a request from our DBAs to be able to create tablespaces larger than 2GB. NFSv2 doesn't do this so I am looking at putting a Linux 2.4.X kernel with NFSv3 support on these servers. Is anyone else running Oracle on Linux 2.4.X kernels with NFSv3 accessing Filers for database storage? Thanks, --[Lance]

RE: Netbackup and tape compression
by Cormier, Darleen 09 Apr '01

09 Apr '01

Hi Simon, NetBackup works fine using the compression drivers, in fact I would say that a very large percentage of users, always use compression in order to get as much data on each tape as possible, and cut down on the costs of their storage. -----Original Message----- From: Clawson, Simon [mailto:simon_clawson@mentorg.com] Sent: Monday, April 09, 2001 5:44 AM To: 'toasters(a)mathworks.com' Subject: Netbackup and tape compression HI Is anyone using Netbackup with tape compression at the DLT drive? Our DLT 7000 will write at faster speeds with compression on, but we dont use it. Is there any reason why we cannot if we use Netbackup to control the write and restore operation?
