I am using a new MacBook Pro that came with Catalina preinstalled, so I am making some adjustments in my workflow.
Previously I have used SuperDuper to back up to external HDDs, each divided into two 500-GB partitions. One of the partitions is for a clone of my internal drive and the other is for archived data that I don’t keep on my internal drive.
Now with APFS, I have erased the external drives and on each of them created a container with two volumes.
Is that better than two containers on each drive?
