Dear all
I am using the same external back up device since several months. I have now the problem that it does not back up anymore.
When I click on "back up now" the it says "Preparing backup....." and it remains this way for hours but it does not start to back up.
I have the external disk with a capacity of 1,000 GB and my used capacity of macbook pro is above 500 GB.
How can I fix this problem?
Thanks for your support.

where is "disk utility"?
When I open my time machine I have either "Options" or "Select Disk.." as options to click on and none of them has the "disk utility" option.
I didn't find "disk utility" on system preferences either.
Disk Utility is an application in your UTILITIES folder. It is not a part of Time Machine.
Ciao.
Run Disk Utility, but if that doesn't solve the problem Time Machine may simply be busy the compacting existing backup and / or deleting expired backups. That can take hours, and if you really are using 500 GB it wouldn't be surprising if Time Machine backup volume is full. That's normal and to be expected, but deleting expired backups might take some time.
To determine what it's doing you can use Console, also in your Mac's Utilities folder. Open system.log and filter for "backupd". That will show you everything Time Machine is doing. Copy and paste those entries in a reply, if you wish. Obscure of delete any information you might consider personal before posting the reply.
