Please read Effective defenses against malware and other threats.

I can confirm that it was my Sophos Antivirus, too. It works if you disable on-access scanning in Sophos, but it cannot be a final solution to be stuck without anti-virus software .
As there are no viruses capable of running on OS X, what difference would it make.

After disabling Sophos I had to reboot to make backups work again.As for the backupd process: It was running between 95 and 99% CPU load most of the time when it was stuck in the "Preparing backup" stage. When the backup is working, the load on my machine is between 10 and 50%.
This just as a further indication: If your backupd process stays at full CPU load (95-99%) in the activity monitor, your backup stage will likely never leave the "Preparing Backup" stage.
Was struggling with this for days on and off before I found this, trying out dozens of different things, repairing the backup disk etc.
I'm having the same problem, I have tried uninstalling Sophos and turning it off, either way Time Machine is stuck preparing backup. I never had any problem before Sierra. The load on my cpu fluctuates between 10% and 50% while it is stuck preparing backup. When the backup is stopped the system idles around 0.50%.
There is some discussion on the Sophos site about this problem, but I can't get a backup no matter what I do.

Oct 5, 2016 10:47 PMby F1208,It seems that most probable causes could be anti-virus software (especially Sophos) and NAS (+ Spotlight?) according to many people here, although there can be many others.
Applying a new fresh HDD with USB direct connection to your Mac, if you don’t mind spending some, could be a possible temporary measure.
That’s what I did eventually and is successful at the moment after many trial and error. In my case: Sophos prevents backing up; NAS puts backing up very much unstable, some times so far completed although very slow, other times stuck in different stages of backup operation; USB HDDs directly connected to the Mac behave very differently in backing up though they have the same specifications. I haven't got clear understanding and solution yet.

Oct 7, 2016 1:38 AMby LeonOJ,FYI: I have the same Time Capsule issue like all of you since updating to Sierra. I do not use anti virus software. I do remember that I had this issue before, after updating to OS Mountain Lion. The problem sorted out it self after several weeks and possibly after a firmware upgrade of Time Capsule. I vaguely remember this Time Capsule firmware update. I have rebooted Time Capsule manually by removing its power cord and also through the AirPort Utility app on my iPhone 6 but the malfunctioning back-up problem persists.

Oct 7, 2016 4:14 AMby Al-kashrie,Its been 2 weeks now since I updated my mac to macOS Sierra and my Time Machine Backup still stuck on "preparing backup" I tried to backup to different partition from the same External hard drive (Seagate) and to my spare hard drive from scratch (new), Please note that I do not have any anti-virus or any anti-malware installed on my mac.
