Been having issues with Time Machine and backup so I ran disk utility on all my drives: iMac drive, iomega external HD and Time Capsule. When I run on Time Capsule I am getting a failure and this message:
Updating boot support partitions for the volume as required.
Unable to mount volume for repair.
Time Machine says "last backup Nov 25, 2015." Can't figure out what is going on. Does anyone have any suggestions?
