How to get Time Machine disk to backup itself (ie, non-
Backups.backupdb on the Time Machine disk)?
Specifically: I moved my
/Users folder to a separate parition, a parition that also houses Time Machine backups (for my boot-SSD parition in
/Users/Backups.backupdb). I also want to Time-Machine backup the /Users/ folders, but Time Machine won't (thus far) let me backup folders/files on the same disk where the Time-Machines backups are stored.
From one standbpoint, it makes sense to keep physically-different disks. (I employ multiple Time-Machine disks for this purpose, including for system above.) However, most backup needs are not due to physical-drive failure, but a "logical/soft" fault (usually me accidently deleting files), and as such, enabling the backups above would prove quite valuable.
