This is a bit difficult,. I will try to explain in detail, please excuse if it get's a little long.
Outlook 2011 crashed, and I was advised to reinstall. That was a mistake, all my local folders in which I had a lot of mails sorted by projects and other criteria disappeared.
Luckily I had a Timemachine backup on our network connected Timecapsule.
I found the backup, which was a .dmg file and copied it to an external USB harddisk and brought everything home, hoping to be able to reconstruct the missing bits.
Well. I doubleclick the .dmg file and up pops a disk image with the wellknown Backups.backupdb folder on it.
In this folder, I see everything … backups all the way back to Nov 22 2012
Wohoooo …. I start TimeMachine. And nothing happens. Nothing at all. It doesn't launch.
I check the settings, and Time Machine ask if I want to use the "new" disk as my backup target, and I can select if i want to replace the old target or use both. I select "Use both".
Since I'm at home and not on the business network, TimeMachine cannot access the TimeCapsule and makes a backup to the external usb HD.
I let it run, and again truies to launch TimeMachine, and whoa … there it is with stars and galaxies and all … except, it only goes back 5 minutes. It will not go back to the date I want/need.
Looking at the USB harddisk, I still have only one file there … Peters backup.dmg … doubleclicking this file results in a disk image on the desktop called Time Machine Backups.
This disk image contains the Backups.backupdb folder and yes … there it is. All of it. backup folders back to Nov 22 2012 with the most recent being just 5 minutes old …
And still, when I launch TimeMachine all I can access is the latest backup.
