I'm a little late in the summary, and perhaps my original question said the HW issues. Thanks to the people below for their contributions: "Anthony Talltree" <aad@verio.net> "Petri Kallberg" <petri.kallberg@sun.com> joe_fletcher@btconnect.com "David Foster" <foster@ncmir.ucsd.edu> "Brandon Cate" <bcate@ipmetrics.com> And a few anonymous netizens directions I had not considered: SOFTWARE: Sun StorEdge Utilization Suite (aka SAM-FS) http://www.sun.com/storage/software/data_mgmt/utilization/ Allows some nice Hierarchical Storage Management tricks - like autoarchiving special filesystems to tape. HP STORAGEWORKS offers some good storage virtualization tools. FALCONSTOR http://www.falconstor.com - provides the same functionality with software. You can supply your own disk for cheap. AMANDA http://www.amanda.org - offers disk-to-disk-to-tape staging if one does not chose commercial backup software. Check out similar HW products Nexsan (http://www.nexsan.com - a strong interest in the NEXSAN devices. Cybernetics http://www.cybernetics.com/ A UK product - http://www.transtec.co.uk/GB/E/products/diskstorage.html?fsid=76de7abd2a3630cc9bc6bba1aca99270 A key feature is whether the disk2disk2tape array supports virtual tape devices (/dev/rmt/*cn). That feature appears to be worth more than $25K US. I seem to have more time and creativity than money, so I am playing with a SUN e450 with 20 slots for disks as my "array", ssh/rsync and looking at upgrading to Veritas Netbackup 5.0 later this year. Thanks to the following 3 fools for letting me know they are out of the office: Hautsalo Kari Schuetz, Henrik Brendan Doherty ---- original message ---- >I'm searching for a disk backup acceleration solution for my backup >environment, often called "tape virtualization". > >I want an inexpensive IDE or SCSI disk array to receive backup >traffic over 100 Mbit & gigabit ethernet and store it for later >backup by Veritas Netbackup 4.5 MP6.
