Backing up two Macs to the same external drive
Hi all,
I would like to backup two different Macs running Big Sur with two different Apple IDs to the same external hard drive.
After having run the first backup, I connect the drive via USB-C to the second Mac. A popup appears, asking me if I would like to create a new backup or if the computer should claim the already existing backups on the drive.
When I click on "New Backup" it tells me set up a new Time Machine password, seeming as if it was about to format the drive and set up a new backup.
Therefore, I chose to "claim the existing backups" which was then followed by Time Machine running a backup.
I wonder if this this was the right choice and if there are now two different Macs' backups on the drive from which I will be able to choose in case of a data emergency, or if Time Machine somehow merged the two backups into one - which would be obviously a problem.
Does anyone of you know what this "claiming" the already existing backups means?
Thanks for your support!
