Hi everyone, first time poster here. I asked this question on the apple support forums, but haven't been able to get an answer so far. Time machine is extremely slow during the beginning of a backup and the end of a backup. It will stop at the first/last couple megabytes and just sit there for up to half an hour, maybe more. As we speak it's sitting on 213.7MB out of a 214.4MB backup and will not move forward. I'm using Mountain Lion 10.8.5 on a 2011 27'' iMac with a 3TB WD external hard drive. Has anybody encountered this problem before, or does anyone know what I could do to fix it? To clarify, I have completed the initial backup without any delays (as far as I know, but I did it overnight so I can't tell). It's the subsequent backups that seem to be having this problem. I know it's not a problem with the drive, because I copied a large video file and it went fast enough, so I'm assuming it's a problem with time machine. I originally tried to partition the drive so I could use one half for archives and one half for backups, but I decided I should just get a new drive for archives. I've backed up, partitioned, formatted, and backed up again, and I'm at a loss and starting to get frustrated with the whole situation. How can I fix this issue?
