After I replaced my Mac's system drive, Time Machine won't go back prior to the change, even though the data's still in the Backups.backupdb directory.
Here's my system:
MacPro 2x2.8 GHz Quad-Core Intel Xeon, 6GB RAM
320 GB internal drive = "MacHD" = system drive
1 TB internal drive = "HD1" = new internal drive that will replace MacHD
2 TB external drive = "BKUP_TM" = Time Machine drive
Here's what I did:
1. Install and format HD1 as Mac OS Extended (Journaled)
2. Clone MacHD to HD1 using SuperDuper, with "copy all files" and "make bootable" options enabled
3. Remove MacHD and reboot computer with HD1 as new system drive
4. Mount BKUP_TM
5. Allow Time Machine software run overnight to do whatever it wants (it recognized the BKUP_TM drive immediately and without my input)
6. Launch Time Machine software after it completes its activity. This is where I noticed that I could only look back in time 1 day to the point of step 5 above.
7. At the finder level, open the BKUP_TM drive and notice that:
A. The data is all held in one directory (as expected)
B. The data still goes back to August 2012 (as expected)
Here's my overall question:
How do I get Time Machine to access the data correctly?
If I have to, I could reinstall the MacHD drive, erase HD1 and start over, but I'm concerned that even that would not get me back to being able to access the full depth of my Time Machine data in the Backups.backupdb directory.
Thanks, in advance, for the help,
I appreciate your help and your attention to keeping my data secure.
Deeper reading of the Pondini site has led me to this course of action:
1. Update OS from 10.6.8 to 10.8.3 (required in order to use the tmutil command that is part of the next step)
2. Follow the Pondini instructions here for "reconnecting to your backups"
3. (hopefully) live happily ever after
I was hoping to not update the OS (I still use one or two appsthat require Rosetta) but maybe this isthe kick in the pants I need to find other solutions for those apps.
If this new plan goes poorly, I still have my original MacHD on the shelf and can go back to it.
I'll update this post later to include the final outcome.
