SD does not erase sparseimage

[patrickmast]

Hi,

I use DS to backup my "VM" drive where I keep my Parallels Virtual Machine Images on. Those files are like 10-15 GB's in size, so I did NOT choose to use "Smart update" because most of the times ALL files changed and needs to be backuped.

Instead I use "Erase ..., than copy file" from the "During copy" drop-down.

Strange thing is, the sparseimage is 221GB, while, when I open the sparseimage, the only folder in the sparseimage is only 55GB.

Does this mean that SD does NOT erased my sparseimage, but instead "deleted" the files IN the sparseimage and writes the newer files into the sparseimage, so that the sparseimage gets bigger and bigger?

Problem is that my backup HD gets full and my next backup fails because it runs out of space.

Thanks
