Backing up Virtual Machine Error

[Frut02]

Hi all,

 

I have been getting this error on a server for some time now when trying to backup using veeam,

 

Creating snapshot

CreateSnapshot failed, vmRef "1632", timeout "1800000", snName "VEEAM BACKUP TEMPORARY SNAPSHOT", snDescription "Please do not delete this snapshot. It is being used by Veeam Backup.", memory "False", quiesce "True"

A snapshot operation cannot be performed.

 

I had it on 1 server and now it seems to be happening on 2 more. Size doesn't seem to have changed and i have plenty of free space. any ideas? I googled it but it just said that veeam couldn't support backups of more that 2TB which none of these are, i think the biggest is 290GB

 

Many Thanks

Which version of Veeam?

 

Which version of vCenter & ESXi?

 

The servers you are backing up, do they have any other snapshots?

 

Can you create snapshots yourself on this particular server? (to see whether Veeam is a victim)

V 4 of vcenter- need to upgrade, veeam v4.1

 

When creating a backup in vcenter i get

Create virtual machine snapshot

Clickview

File is larger than

the maximum size supported by

datastore '

 

Starting to think its more to do with vmware. i have enough space on the data store.

Hi Nick,

 

It's most definitely a problem with VMware if you can't even take a snapshot from the vSphere client.

 

Are you using any RDMs?

 

VMware KB: Creating a snapshot for a virtual machine fails with the error: File is larger than maximum file size supported

 

VMware KB: Storage vMotion or cloning a virtual machine fails with the error: File is larger than the maximum size supported by datastore

 

What type of datastore are you using? NFS or VMFS? (& how big is it?)
