My iMac had an SSD startup drive (called SSD) and a 3TB internal hard drive (MacintoshHD) duplicating the SSD as well as containing the User folders and all data.
MacintoshHD died last week. I reinstalled the original 1TB hard drive (also called MacintoshHD but not currently being used) and bought an external Thunderbolt 4TB drive. Onto this I've copied my home folder (at root level so the supplied LaCie setup software is untouched in the root too).
I have successfully restored everything but my Movies and Downloads folders (which stupidly I excluded from TM because of space issues!) by copying the contents of the
.../Backups.backupdb/Macintosh/Users/operacentric folder to the new drive. Thus the new drive doesn't duplicate all users and system folders that the original had.
I want Time Machine to continue using the existing backup set (at least until I can afford an 8TB new drive when I can start again!) It has backups for SSD and MacintoshHD until the last backup but one (which is when the HDD failed). So the Latest folder contains an SSD backup but the previous one has folders for both drives.
Having read the manual page and various guides here and elsewhere about TMUTIL, I believe I can use Associatedisk to relink the backup to the new drive. However, they don't deal with the issue of having two drives in the backup. I am not quite sure of the syntax - do I use the root drive name (LaCie), the Users folder or the operacentric folder?
sudo tmutil associatedisk [-a] mount_point snapshot_volume
Is the mount_point:
Can I use the actual snapshot volume rather than the (missing) link in Latest?, so
or do I enter the same point of the hierarchy
All the posts I've seen here relate to a single drive - not sure how to work with the internal and the external...
