veeam job for hardware 4 VM

[ald]

hello
I am implementing veeam 8 to backup an heterogeneous VMware infrastructure
I have all versions of VM hardware and most of my v7 and higher VMs have CBT disabled
the Infrastructure is working on vSphere 5.5 and vSphere 5.0

I was surprised that no issues appeared about cbt disabled and in the log I saw that the jobs are automaticaly enabling cbt on the VMs with v7 and higher HW
so first session the veeam reads all the disk and after only changes.

and I was surprised that with vm version 4 I have incremental backups too! the only difference is that the entire disk is read but only changes are transferred

I am very happy with that, my question is, can we estimate the time Veeam reads data (for exemple for a 100 GB disk) on a direct san transfert mode for VMs with v4 hardware?

to the question why dont you upgrade ? my response is ASAP but we cant wait the upgrade to backup VMs

thanks for answer if possible

Hi Daniel,

The time required to do incremental backup via scanning the entire disk, will be equal to your full backup times. Based on the performance rates you have, you should be able to estimate that.

Thanks!
