Veeam backup files exceed provision size

Post by nestorius » Jan 18, 2017 9:54 am

Hi; I have a problem. My virtual machine's backup vmdk files exceed original size. Why this problem occurs and how can I solve this. Thanks...

Hi reha,

Do you mean that VBK file or incremental restore points exceed the size of the used space of your VM?

Thanks!

All .vmdk files total size in my replica app. 420GB, but replica's disk provision size is 314GB.

Are you using the same disk format? Do you compare total VM size (including snapshots) or just source VMDKs?

Use same format. I compare only vmdk's original vm and replica vm.

Can you please post two screenshots of the disk size you compare? It would help us to better understand the root cause if this difference.

By the way, I'm wondering whether deleted file blocks exclusion is enabled. Thanks.

Not sure what confuses you here. I do not see anything unexpected on these screenshots, in terms of VMDK size.

In first snapshot, left side of picture is my original vm, there is no problem here but right side is my replica, this vm's vmdk total size is exceed replica's provisioned disk size.

In second snaphot, there is no problem, this is my original vm.

Thanks.

Do you mean the total size of all VMDK files, including restore points?

Each of them contains changes occurred inside original VM between corresponding job cycles, so it is expected they occupy the space.

Not sure what exceed you're talking about. You will be able to failover to any of the existing restore points - the replica VM will be reverted to the corresponding snapshot.
