good god, backup really is that complicated
at least if one wants to duplicate the convenience of apple's Time Capsule.
i've been combing over posts @ readynas.com, which is an excellent resource for Netgear NAS products. though it seems easier than ever to run Time Machine software with non-Apple devices, there are still a lot of issues. upgrading osx versions, running multiple Time Machine users, and running Parallels caused issues for a number of users.
those anecdotes are also peppered with cries of "NAS isn't a backup solution!" Which is a shame, given that's exactly what i wanted to use it for. so then i was pricing out 2 TB external drives to back up the NAS.
Time Machine tracks revisions to files, such that one restore their computer to the exact state from a date in the past (chewing up a lot of extra disk space in the process). That's a neat use case, but one I don't really need. I version my own files when it's important to me, what I need from a backup system is something for that rainy day if my laptop is stolen or the drive dies.
iow, I need the latest snapshot, that's it.
seems I already have everything I need for that: external firewire drives and Super Duper. I contacted the author and he confirmed for me that NAS solutions, while having some nice features, doesn't allow Super Duper to make a bootable backup the way it does with a dedicated device.
so I suppose I'll stick with my 3-prong approach, using Mobile Me Sync, Backup of some files to the apple servers, and Super Duper for the entire image.
