Bonjour tout le monde, j'ai encore besoin de votre aide.
J'utilise actuellement la version de NetBackup 7.0.1 avec vCenter Server v4.0.0 et vSphere client v4.0.0.
Actuellement, lorsque je procede à un backup de VM, je ne sauvegarde que le snapshot utilisé lors du backup. Une fois le restore terminée je ne vois qu'un seul snapshot, tous les autres snapshots crées sur cette VM ont étés supprimés.
J'aimerais savoir si il est possible lors d'un backup de VM, de sauvegardé tous les snapshots crées sur cette VM ?
Faudrait-il que j'upgrade ma version de Vcenter ou NetBackup ?
Merci pour votre aide !

Yes, i have 2 or 3 snapshots in the "snapshot manager" when i backup the VM.
But when i need to restore it, into the "snapshot manager" i loose all my snapshots.
May be i need to configure something into vCenter or maybe the version of NetBackup doesn't have this feature ?
Thx,

First of all, running a VM with 2 or 3 snapshots will degrade the performance of the VM (unless you have this VM setup for some training/lab environment?)
There is a section in the NetBackup Admin Guide for Vmware
taken from 7.1.0 pdf guide.
Existing snapshot handling
I understand what you want to see but based on how the backup software talks to the vstorage api it just says give me a backup of the current state. Now this might the state of the VM at Snapshot #2 and not give you the state of the VM at Snapshot #1 - as well - in that backup job.!
A snapshot preserves the state and data of a virtual machine at a specific point in time.
My initial thoughts are consolidate the snapshots. Then backup. But you must have a reason for running on them.! (care to explain?)
Performing regular backups (when there are no multiple snapshots existing already will give you these states to restore from anyway - in a way)
Maybe you can get what you want, but not in NetBackup?
Power off the VM and Export it. This should take lock stock everything about this VM including all snapshot deltas etc.

Yes i have a training\lab environment for testing applications so i have a lot of snapshot for different VM..
I tryed to found a solution to backup my VM with all the snapshots created on it.
The only way i found it's to backup the VM one by one with all the differents snapshots...
The snapshot taken it's saved on what type of file? Can i backed up these files like a data and restore them on ESX after restore of the VM ?

Please read another good document from VMware
Best practices for virtual machine snapshots in the VMware environment
I am trying to think there is a better way for you to perform what your doing but this would be from a VMware perspective first and then NetBackup.
If you want to have a training VM, that you test installing applications on why not use non-persistent disk option.
If you power-off or restore from snapshot any changes to the disk are discarded.
There is some discussion over on the Veeam forums that you would possibly have to bypass the vstorage api

Another thought. If this is a training/lab VM (with a snapshot chain). Power it off.
Take a file based backup of the VM files.
Can't think how you do this with Netbackup
But if you downloaded the files to your PC and then uploaded to datastore you would have to readd into the vmware inventory.
Found this discussion which although does reference another product it explains the tech as to why you cant do what you want.
Over and out.
