EMC Dantz tiptoes into support for Xsan this week with the release of Retrospect 6.1 for Mac, a free update for Retrospect 6 users. The release notes convey a whole laundry list of caveats, though — don't install it on the SAN itself, forget about creation dates, forget about Access Control Lists, forget about subvolumes, expect some compare errors. Still, promising, and I'm sure we'll give it a try here ... meanwhile I'd welcome any backup stories from those of you using competing products, successful or otherwise.
