How to merge two backups into one?
I have two macs [Lion and Mavericks (soon to be High Sierra)] backed up by Time Machine on two different external drives (backups.backupdb/user's mac1 and backups.backupdb/user's mac2). One of these drives is large enough to hold the contents of both (4x if need be).
How can I merge these backups into one? Or in other words, copy Backups.backupdb/mac1 to the larger disk already containing backups.backupdb/user's mac2 so both would be under the same backups.backupdb roof?
