VMWARE - Datastore - Backup with Veeam or other programs - Snapshot
During a scheduled backup of the virtual machine, eg with Veeam, the first time a backup is created, a warning message appears with the following message:
Disk has been skipped because it was excluded from processing by user
The specified disk was created using Disk Independent-Durable or Not Durable disk mode. The result is that the data is immediately and permanently written to the hard disk, or not. In both cases, the data is not stored in snapshots.
Shut down the virtual machine and set the disk mode to Dependent. Then snapshots are taken and your data backed up.
