Time Machine refuses to backup automatically...

[Rogier]

Hi guys,

I am having this weird problem with TM. Despite having switched it on, it does not back up anymore on the times it says it will. On the time the next backup is scheduled, the timer changes to 1 hour later, without actually making a backup.
The only way I can get the backup working is by doing this manually by right-clicking the TM icon in the dock. Only these manual backups are present in the TM application.

Any ideas how I can get the automatic backup working again?

I had this problem once. I fixed it by telling Time Machine to use no drive to back up, waiting a few seconds, then telling it to use the drive again. This action triggered an immediate backup, then automatic backups resumed as normal. Hope it helps.

Thanks for your swift reply! Unfortunately, this did not seem to help though... Any other ideas?
