Slow Restores on Netware
Is it me or is a restore of Netware data slow? I get at best 5.6g per hour off of a 21g per hour drive. TSM backs it up fast but takes way to long to restore. Does anyone else have this problem and if so what do you do?

Re: Slow Restores on Netware
Netware uses A LOT of small files, the Netware filesystem is not fast enough to build the filestructure etc. That's most of the times the performance problems with Netware en NT Fileservers.

Re: Slow Restores on Netware
As much as I do agree with the shrug issue at times, I fail to see where the fact that restores take ages is actually connected to the Netware side. We have exactly the same issue, and with all the "experts" we'v had here testing it out, not one has been able to point to the Netware side being the problem, and every one has managed to find problems with the TSM side. Be it very slow tape access, bad indexing, etc. I would be wrong to point the finger specifically at the TSM, and would go as far as to say that TSM and Netware do not quite mesh as Netware and other backups software do, but that's something I'v been over before on this list. The slow restores I have on some of my NT servers...do I shrug and say NT ? And the Unix's ?

Re: Slow Restores on Netware
More $.02 ... Are you compressing the Netware volume? Do you have any virus scanner running while the restore is running? Bill Boyer "I haven't lost my mind.

Re: Slow Restores on Netware
To add another thought. Last time I had to restore a NetWare server we ran into a problem of MTU size. Once we fixed that the restore went very quickly.

It's you. :-) Seriously, though, we'd need a lot more information to gauge why the restorals are slow, as has been explored innumerable times on the mailing list... Tape drive type, collocation type and locality of data relative to restoral needs, restoral type, networking, disk speed, file system condition, client/server load, etc. (I summarize factors in the "Restoral performance" entry in ADSM.QuickFacts.) Identifying bottlenecks is one of the tasks for which we all get paid so much. :-$ Richard Sims, BU

Re: Slow Restores on Netware
We regularly get 8-10gb/hour on Netware restores. These servers typically have 100+gb of disk & 1 million+ files on them. Similar performance on NT. A bit more detail on your client & server configurations would be helpful.

Rather than just shrugging and saying "Netware", I'd like to offer more useful dialog. Not knowing what your network is like, I'd say that a 5GB+/hour restore on Netware is pretty damn good, considering that Netware, like Windows, is comprised of a zillion small files and a rather convoluted directory structure. It takes a while for those Intel-dependent OSs a while to rebuild file structures. -- Mark Stapleton ([EMAIL PROTECTED])

If the Netware is compressed at the volume level, there is no compression going on during the file transfers to or from TSM. The very nature of the volume strucutre itself is compressed, and puts no compression stress on either the client or TSM server. -- Mark Stapleton ([EMAIL PROTECTED])
