Since sometime around January, I've experienced intermittent Time Machine failing to backup (using an Apple Time Capsule 3 TB (with 1.6 TB of free space, and the Time Capsule HD works just fine for everything else. I can download & upload files to it with no issues). I just happened to notice that my machine hasn't backed up since June 5th. I tried to initiate a backup, but it just quits somewhere in the middle. I've had this happen 3-4 times this year & in the past, I just deleted the entire old backup, then created a new backup. It took a long time, but it worked. Now, I'm not even able to create the initial backup. It seems to keep failing without warning. I have about 225 GB to backup & the first time, I got about 175 GB backed up, and then it stopped. Then I did a verify backups step & tried it again & it started kind off where it left off (starting with 64 GB to backup), then it too failed, and I did another verify backup & started again & this time it started as a 20 GB backup. This process keeps repeating, I am down to a 345 MB backup now, but it still doesn't seem to want to finish backing up. Has anyone else seen this, or have any ideas what might be going on? Thanks in advance.
