Thanks for the replies. I have taken this remark and left the base vdi
in ~/vbox, but removed a snapshot. As a result I have now 1 base vdi
in ~/vbox and a {...........}.vdi file in
~/.VirtualBox/Machines/Win2K/Snapshots/.
Fine.
My understanding is the the base vdi does not change, but that changes
are made to this differencing {...}.vdi. But the base vdi seems to be
getting a now date info on the file every time I open the guest,
although the size remains the same (as expected). The new date info
forces my backup program to try to make a backup every time of this
file, which is quite ennoying as the tape size is limited and the base
file quite large.
Is my understanding correct and can I change that "date modifying"
behaviour? Or is indeed also the contents modified?
