Hi, I'm confused here about device modes, and we don't appear to be getting proper compression on actual backups: Can someone tell me what dev/nst0a, nst0l and nst0m do? I've read the man page for st
[...] Yup, but the driver isn't going to control the compression algorithm or anything like that. If you're getting anything above the native capacity, then it must at least be enabling compression.

Thanks, Darren, This was helpful. After a few more backups (no configuration changes), things are looking up. We had one tape fill up at 372 GB and two others at 440 and 445 GB respectively, so I gue
No, I don't think so. That's the output I always see, so I just assume that it's a reporting difference. One utility calls the first slot 0, one calls it 1. It's still the first slot. I don't think

Sorry for some of the duplicate postings, but it appeared that some of my replies were not getting distributed. I guess it was just lag time. Would these two operations be equivalent?: 1. mt -f /dev/
Probably. I'm not a linux expert (more Solaris), so the idea of defining compression with mt surprises me, but it seems consistent. I suppose. I've never tried to disable compression for networker's
