VM server no backup

I have a ESX server and VMs server(exchange 2007 enterprise) on it.One of my vm i cant do veeam backup,veeam replication or snapshot.

I need to take a backup that server somehow.
My question is : is there a possibility to take a backup that VM server(exchange 2007 enterprise) when there is no way with snapshot ,veeam replication or veem backup ?

1.  a snapshot isn't a backup.  it just saves changes a 2nd vmdk that can grow and fill up your datastore if you don't have enough free space.

2. nearly all backup apps use the snapshot utility to enable them to copy the data from the original vmdk.

so, the best place to start is probably find out why you can't take a snapshot.  What error do you see when trying to take a snapshot?

Are the ports open to be able to take a backup .... also hope you have the updated Agent on it if you have made any upgrades to the Master Agent or Backup server :)

Also check if you can telnet to ports required to take backup ?
As said earlier check for errors on backup server and on the Backup console when you try to take backup ?
Did you try to check the Netbackup services is running on the Exchange 2007 server ? If so try to restart and check :)
Also  check if the writers and providers are in Stable state ? If not may need to restart IS to bring them to stable state.

The issue you have, is because the datastore has the incorrect block size for the size of the virtual machine disk.

ALL Backup Applications that use the Snapshot method will fail.

You need to address the issue:-

1. Create a new datastore with the correct block size.
2. Move the Virtual machine from the old datastore to the new datastore with correct block size.

You could power down the virtual server and the server it resides on and do a full hardware clone of the hard drives, one by one. In fact I have done this recently and it saved me from some serious downtime and data loss when a subsequent server migration failed. It is not the easy or inexpensive way to go, but it works every time. There are simple, inexpensive tools for this available that let you just hook up hard drives back to back and press a button. Get one of those tools for each hard drive or prepare for a long night - they take a few hours on larger drives (1TB or more). You will need a backup hard drive with equal or greater capacity to the server drive for each server drive. Make sure to take them out and put them back in the exact same place. Make sure the target drives have no data on them as the entire drive will be overwritten.
When completed, you will be able to swap in either the original drives or the backup versions and the operating system should not be able to tell the difference. However, if you do replace the drives you will have to recreate the RAID array, if any, using the same parameters as the original, so make sure to note the settings on the RAID adapter.
