I maintain regular backups of my systems: three (3) Macbook Pros, vintage 2011, 2016 & 2019. I use Time Machine for backups now, and I have so far been fortunate enough to not need to use a backup to restore a system. However, I feel that my good luck may work against me if and when I do need to restore a system.
Is there some method or process by which I could make a "test restoration" of a Time Machine backup to gain some practice or familiarity without putting my system at risk? For example, perhaps I could restore the backup to an external SSD, and then boot from that external drive?
