I have some files on a system volume that are already in a Time Machine backup, but would like to force Time Machine to back them up again. Is this possible?
I know I can do this by modifying the file(s) slightly, but I'd rather avoid doing that.
The system volume in question is an HFS+ volume, so my understanding is that Time Machine uses fsevents to track changes; is there a way to force an fsevent for a file that hasn't actually changed, such that Time Machine will back it up again?
I realise this is a strange question, but my reason for wanting to do this is that I've used HFS compression (via
afsctool) to compress a large number of files, and I'd like the compressed version to be copied into Time Machine to eventually save space there as well.
So, is it possible to force Time Machine to fully backup a file that is already in the backup target?
