The goal would be to hardly control the creation time of the backup.
Eg : The application people wants a consistency point at 18h30 (+/- some minutes) :
- A first job (not handled by veeam) creates the snapshot on demand. It can synchronously say to the batch that the snapshot was taken.
- Next, the batch (or the veeam scheduler) launch a backup job with settings saying to use the snapshot "XXXMYAPP *".
Even if for any reason the backup task occurs in 5 hours, we have an image at the requested time.
