Time Machine backup disk space
This is on an iMac 2021 M1 using Ventura 13.6. It has a 1Tb drive of which typically ~100Gb is used. I needed to do some backing up of old files onto external SSDs and in the process I copied ~800Gb onto the iMac HD and then copied it back to a SSD and deleted from the iMac HD. And in the process Time Machine updates ticked over. After some to-ing and fro-ing I now have two files on the Time Machine backup SSD, one from yesterday of ~700Gb and one from today of ~100Gb. If I need to use the backup I would use the current file. Can I delete the older file to make sure there is sufficient space on the backup drive in case it is needed?
