Tima Machine backup stalls every time

[lexvo]

I have Time Machine backing up to an external drive, connected by USB.　


Today I noticed that my iMac doesn’t make time machine backups anymore. The backup starts but hangs after a while. It has to backup 2GB and stalls at a few hundred MB every time.　

I find it very strange, this happens out of the blue. I never had problems with time machine before, is has been working reliable for years.

I tried several things to solve the problem:

• PRAM reset, didn't help
• NVRAM reset, didn't help
• unmounting my external HD, remove the time machine plist file, reboot iMac and mount the external HD again, didn't help
• Check my external drive with disk utility, drive is OK
• Check my internal drive with disk utility, drive is OK
• I also tried time machine backup to another external drive, but this stalled also　

Anyone a suggestion how I can solve this? Thanks in advance.
