Time machine is slow says it will take 29 days

Typically the time it shows is wrong. Another reason why one would get such a long reading because the drive in which Time Machine is saving too is running out of space. Time Machine will delete old backups in a drive but this does not mean a drive has lots of space available in it.

Hi guys,

Have y'all checked Spotlight yet?

I was experiencing the same problem. A TM backup with a size of about 670 MB took more than 24 hours.

Did some digging and found out that Spotlight's indexing process was running.

Switched it off using:

sudo mdutil -a -i off

TM backup is now back on its original speed, AFAICT.

HTH,

Gerard
