I am running YOSEMITE on a MBPro and have found some "odd behaviour" with Time Capsule/Time Machine.
I have no trouble connecting to the Airport Disk for the wireless internet connection.
However, sometimes when I want to do a manual backup (i.e. I have not set Time Machine for automatic/hourly backups), I receive a message that Time Machine "is busy and cannot connect" AND "try again later."
Other times, I have no issue with making the backup as usual on Airport Disk/Time Capsule . . . although there may be a bit more of a wait at the "preparing for backup" stage before the backup begins.
Also: I have been able to ENTER Time Machine and view all the backup folders there - oldest to latest. However, sometimes, upon entering, the display page, mouse and keyboard will freeze
and I cannot page through the folders or files. The only option then is to press the power button on the MBPro and reboot.
Any ideas as to what may be going on with the Airport Disk/Time Capsule/Time Machine?
Thanks a bunch.
