First Snapshot size of the VM.

First Snapshot size of the VM.

If I take a snapshot of the VM the first time. Is the size of the snapshot going to be roughly the same size as the VM or it is going to be just an empty file.

Thank you

Almost ZERO, and it will grow, at a rate of approx 1GB per hour, based on changes in the VM.

Initial Snapshot size - (244kb)

The question is indeed whether the snapshot file is ever growing, or only reflecting changed blocks - if the same block is rewritten several times in the VM, does it also create new blocks in the snapshot? I guess that is something which should be made clear here, too - for reference ;-).

To answer my question posted above: Snapshot files cannot extend to a size larger than the original virtual disk files. The snapshot file contains all changed blocks, and if a block has been changed 100 times, it still is only a single block - the snapshot reflects only that last change for this block.
