In your scenario of changing files A and B, if you restore you will get whatever was current, both files, from the backup. You might have an issue if you restore on the day the back up disk is changed. Ideally one would keep the same back up disk connected at all times. Have a second drive and use a program like SuperDuper or CCC to periodically duplicate the Time Machine drive to the second drive. If done weekly you essentially have the same level of back up but with no hacks. If you want an offsite backup, swap the secondary back up disk weekly. fumanchu: even though Time Machine does and incremental backup, all the files are there to recover.

Then I realized it can't work right. Since it seems to be working for you either I'm mistaken and am glad to know it or you are in for a nasty surpise when you try to restore!! here's the issue I perceive. suppose I'm occasionally changing two files: A and B. in week 1 I edit A but not B. In week 2 I edit B and A. In week 3 I edit A again. The I decide I need to revert my home directory. when I do this I can't get a coherent set of A and B: if I revert to the current time machine disk then I get last the B from 2 weeks ago and this weeks A. With just two files of course this is not a big deal but there's hunderds of diles many I don't even know about (e.g. preferences and application support) that won't be self consistent with each other. to be clear by self consistent I mean that if I restore the files to a given date, then the restored image contains the files that were present on that date. I'm basing this on the assumption I made that if B got backed up last week then the OS marks B as "clean". So it won't get backed up this week (to the new disk).

I'd improve it (if you have the dollars) so that you have 5 disks, one for each day of the week. You could still keep just one off site if you need (or more) but it will give you daily incremental backups so you can recover the right version of that file you've been working on all week before MS Word trashes it and you don't notice the mangling till 3 edits later ;) That’s a nice automated solution (and pretty useful to non-retards!!).

If you log out, I don't believe the script will run when you press the button. As I said, not the perfect solution. But still a nice solution I think.

What we're all waiting for is your review of iDrum for the iPhone. Bring it on Beat Boy! Nice of you to share, but this is probably of limited use to the general pubic (sic).
