Hi,

I did this.
I took a VMware snapshot yest evening. And it has been grown within
12hrs now aprox 5GB. I'll do some further monitoring, but it seem
indeed, there's not so many data which changes daily as dump might assume.

And I have another idea 'coz of rsync copying the whole .vdmk file over-
this could be related to access time. Obviously the times changes as the
file is under continously access from the ESX host. I'll see if I can
skip the time identification and force rsyn just to check the content.

For the 2GB chunks idea it'll take quiet a while to migrate the 540GB
vmdk to 2GB chunks. Oh, and I think ESX does not support this type...

Greetings

Christian
