Entire VM restore with Quick Rollback question

[adam900331]

Hy!

I am testing the Entire VM Restore with Quick Rollback. With the Quick Rollback option only restore the changed data block when different from the last backup. I create a incremental backup on a VM, and after it remove the C:\Windows\System32\winlogon.exe and winload.efi to make a mistake during boot. (create a wrong VM:) ) Thios two file size is about 3Mb. When I do an Entire VM Restore with Quick Rollback, I noticed, that the restored data is 1.6Gb. Why? Why not only 3Mb?

Thanks.

Hi Adam

There are many more blocks rewritten in a windows machine than just the ones you edit or remove.
We have eventlogs, we have cache files, we have config files. And each application that is running also have their files changed all the times. They all have to be rolled back in a vm restore.

Thanks
Fabian
