Backup virtual Machines with Backup Exec 2012 V-Ray
i have a litte question about the backupdataflow when performing backups with VMware Agent.
For example: I have a VMware Datacenter with two ESX Hostservers and a seperate physical machine with VMware
vShpere Server installed to do the administration of the Datacenter. This server also has installed Backup Exec 2012 with V-Ray license.
The virtual machines data (configuration files, virutal hard disks) are saved in a NFS Shares which are configured as datastores at the esx hosts.
The virtual machines harddisk are created as thin provisioned.
Now, if i perform a Backup of a VM (with 2 vmdk files, max space 100GB, but only with 20 GB data on it) via VMware Agent, the hole Data 200GB is transmitted to the BE Server, so the Backupjob takes much longer.
But if i take a look at the tape which was used for this job, there is only e. g. 20 GB used?
What is causing this?
I hope anybody has an idea.
