What do you mean with "Windows Exchange"?
All I know is MS Exchange Server. That's a software package that functions as a server for e-mail (and calendar, contacts, notes and such). But not for backup.
My workplace is a Mac-island in a large, Byzantine, Windows-based organization - Macs are officially not supported, which means that even the couple of Apple enthusiasts in IT (who we almost never see face-to-face) have to place Mac problems low on their list of priorities.
Over the last couple of years, connection to the Exchange server via SMB has become slower and slower (esp since Lion), to the point that most staff aren't even using it anymore. I've put in a couple of requests for IT to see whether they can optimize the Exchange server or suggest solutions, but nothing's come of it.
Question is, what now? We have to have a standardized system for backing up data in our group (we're legally obliged to retain data and I'm concerned that younger staff aren't backing up properly anymore); plus, my daily workflow is ruined, as I'm constantly waiting for the Mac to index(?) the server file structure. Possible solutions?:
We buy an external harddrive for each computer (not so good, cause harddrives fail, get stolen, etc.)
We find a way of backing up to Windows Exchange from OSX on a regular basis (say each night). This is what we're supposed to do - leave the IT to the experts. Con - many people take their laptops home at night.
We set up an Apple server micro-environment with RAID back-up, which in turn backs up to Exchange. Cons - I don't whether that would work (it would sit "on-top-of" the Windows environment I guess - which we have zero control over and which is very restrictive - we don't even have wi-fi due to data protection regs), and I'll likely then be responsible for all the ensuing IT trouble-shooting, which I reckon could be like shoveling snow all day.
