I have 2 questions about Windows 8.1's System Image Backup:
I run this command: wbadmin start backup -allCritical -vssFull -quiet -backupTarget:E:\
1. Why does this backup take 36% more space than the data on source disk? (Acronis backup takes much less.)
2. I find data of only one backup while the command is supposed to do incremental backups as well. How to do backup of more than one day?
