Hi all, When we recently went overseas, I bought a 1TB portable usb drive for ongoing back-ups of our MacBook Pro (I already had desktop drive backups at home).
The MacBook Pro has a nominal 200GB HD and currently shows a capacity of 185.99GB with 136.38 on disk and 49.61GB available. I would normally keep my clone and TM backup on separate drives - but I only wanted to cart one additional drive around Europe - so I partitioned the drive with a 186GB partition (to match the internal drive) for a SuperDuper clone leaving a 745.07GB partition for ongoing TM back-ups. The initial TM back-up and SuperDuper clone obviously took some time on a 4200 rpm USB drive - but everything went OK. On our holidays, I had the TM off and did manual back-ups as I felt was needed - other than for photo storage the main laptop use was internet/email. I had the SuperDuper set as a Smart Update saved script but didn't really use it much - I don't really remember but I may have run Smart Update once or twice on the holiday. So far all is normal and as expected. Now we are back home and I'm back on my iMac as my main computer. All the holiday stuff I need was synched via Dropbox anyway so was waiting for me. However, I have done a little bit of tidying up on the laptop - so I thought a catchup backup was in order. The TM backup went smoothly (around 4GB, I think) and a "Get Info" on the TM partition shows only 121.07 GB used - I do have around 20GB excluded from TM but it still shows I haven't been doing big changes on the machine. So, here's the problem/puzzle - I just started the SuperDuper Smart Update and it is taking forever. The reason is not hard to find - we are up to around 50GB evaluated 0GB up to date and so 50GB copied. In other words SuperDuper seems to think that every file needs updating. Now I'm pretty sure that every file on the computer HASN'T been changes since the last update and TM obviously doesn't think so or the TM backup would be MUCH larger - so what gives??! The only thing that occurred to me was that as we travelled through the different time zones, the "modified" time/date stamp of the files at the last update may have been in Europe time around 8 hours behind us? and now the laptop is on Oz time all the files are 8 hours "newer" than the last clone? TM is obviously smart enough to cope with all that, but perhaps the SuperDuper Smart Update isn't (smart enough!). Anybody have any thoughts or experience with this (SuperDuper smart updates across time zones) - I did a quick google but nothing obviously relevant turned up. Anyway, it's not really a problem - more a puzzle - and I do like to know WHY ;o) Cheers Neil -- Neil R.
