time machine all recent backups missing after reboot
I accidentally deleted an important file on my mac, and when i opened time machine, i discovered that my it couldn't be found wirelessly. The green light was still on the front of the device but my mac couldn't locate it.
I'm not sure exactly how long it has been since timecapsule made a backup, but i have a clear memory of it working about 3 months ago.
I rebooted it and now its running, and has backed up.
My problem is when i go into the "star wars screen" to view past backups, the only backups are from today and then next most recent are from July 2012 when i first bought the time capsule, everything else in between has disappeared. It definitely had 2013 backups.
Are the backups from 2013 still there and can't be seen, or have they been deleted permanently?
