Issues in completing a back up successfully

I've connected the external drive to the mac and started a back up. It is currently stuck at 452.9 Mb of 22.83 Gb.

Time machine buddy logs says:

Starting automatic backup

Backing up to /dev/disk1s3: /Volumes/FreeAgent GoFlex Drive/Backups.backupdb

Event store UUIDs don't match for volume: Macintosh HD

Deep event scan at path:/ reason:must scan subdirs|new event db|

process backupd[3263] thread 310512 caught burning CPU! It used more than 50% CPU (Actual recent usage: 68%) over 180 seconds. thread lifetime cpu usage 90.051256 seconds, (58.936719 user, 31.114537 system) ledger info: balance: 90002304555 credit: 90002304555 debit: 0 limit: 90000000000 (50%) period: 180000000000 time since last refill (ns): 131241331490

Finished scan

Not using file event preflight for Macintosh HD

Found 495710 files (20.76 GB) needing backup

26.32 GB required (including padding), 1.13 TB available

Does anybody have an idea of what to do?

I should also point out that when I attach the external drive (Seagate) it doesn't come up on the desktop as a time machine capsule.

Thanks in advance for your help!

MacBook Air (11-inch Mid 2011), OS X Mavericks (10.9.2)

You have some nasty process burning your CPU..

Stop thread 310512..

Some applications can interfere with TM backups..

I suggest you turn off all processes and even kill anything in activity monitor that is chewing CPU cycles so the backup can work.

I should also point out that when I attach the external drive (Seagate) it doesn't come up on the desktop as a time machine capsule.

It should not.. Time Capsule is network drive.. a seagate freeagent is external drive.. entirely different.

I had the same problem. Four separate attempts to create a new backup, on a "clean" drive (just erased), on two separate external drives all hung (for hours). This was on a system that had been completely erased and reimaged that day.

I rebooted the system, didn't start any other applications, and started the time machine backups over from scratch. Each on completed nominally (in the time frame I expected).

Since then, time machine backups have completed nominally without hanging.
