Does anyone have any experience with large capacity tape drives?
We are looking into providing a central "backup server" for our
uVAX and SUN workstations. This system would use rdump to take
disk backups. However, we'd like to avoid the vast number of
1/2 tape reels this would require. Recently there have been ads
for helical scan technology tape drives. Has anyone actually used
them? Any other comments on backing up disks over Ethernet?

We've been using an Exebyte EXB-8200 tape drive for about 2 months, now, and it seems to work just fine. This drive uses 8-mm Video Tapes to hold about 2.5GB of data; we perform daily dumps from about 6 machines that are NFS'ed together. -- Tim Olson Advanced Micro Devices (tim@crackle.amd.com)

Any other comments on backing up disks over Ethernet? We've been using MegaTape Corp's MegaTape 500 tape drive for a couple of years now with great success on our Pyramid 9820. It's a 500 Mbyte-per-cartridge (MDC500 cartridges), cassette tape drive, with the cassettes costing about 150 dollars each, and being between 1 and 2 VHS video cartridges in size. It has a standard, daisy-chainable Pertec I/F. They also do a 750 Mbyte version. We've no experience of trans-Ethernet backups, since we the Pyramid is the only *real* machine we have on the Ethernet - I don't count the PCs :-) I don't work. For Pyramid or MegaTape - I'm just satisfied. As a user. -- Enjoy, yerluvinunclesimon Opinions are mine - my cat has her own ideas Reach me at sar@datcon.co.uk, or ...!mcvax!ukc!pyrltd!datcon!sar
