Super Duper Backup and Time Machine on Same Drive
 

I have got my Super Duper backup and my Time Machine backup on the same external USB drive as per the FAQ. This is working brilliantly but I'm concerned about eventually running out of space on the USB drive.

According to the Time Machine documentation it will carry on writing weekly backups to the drive until it is full (and will then presumably start deleting old stuff). However what if I then want to now do another Super Duper backup? If this requires any more disk space than the current one, then surely it will fail!

So how do I go about making sure there is always some free space on my external drive? I've searched the net and can't find any easy way of restricting the amount of disk used by Time Machine. Are there any other options?

Unfortunately, there's no obvious way to restrict Time Machine's backup size, except by partitioning. Of course, if you run out of space, you can delete some Time Machine data... or you can start backing up with SuperDuper! to another drive.

Thanks
 

OK, thanks, I'll probaby repartition the USB drive in that case.
