I have 2 apple macbooks doing backups to my mirror device.
Both have been doing hourly backups without problem for over 2 months.
I can use time machine and view the backups to when I installed it.
However all of a sudden I am getting this message on BOTH macbooks.
I dont really want to delete 2 1/2 months of back ups but thats what its telling me to do on BOTH machines.
I have rebooted the mirror drive and still getting same error.
any idea’s ?
