I have used VSS API to make snapshot of C:. The program fails with VSS exception. But when I try to create snapshot of same volume using VSS Admin it completes successfully.
I found the shadow storage space is less then 300 mb and hence it caused my program to fail. Increasing the space of shadow storage worked for me.
My questions are:
- How does VSS Admin work fine even if the shadowstorage space is less than 300MB?
- Why can't a program created using VSS API also create a snapshot?
What's missing?
