EqualLogic Veeam followup

So far Veeam has been treating me well. When backing up multiple VM’s at the same time it really does peg out the processor. I’m glad I choose to install into physical instead of virtual.

I of course had an iSCSI attached volume that veeam can’t ‘see’ so I had to remedy that by moving mailboxes all over crime and creation. Gave me a

Discovery phase failed.
Cannot add volumes to the snapshot set.
Cannot add a volume to the snapshot set. Volume name: [\\?\Volume{fca370fa-f010-11de-b405-005056b07383}\].
Cannot add volume to the set of volumes that should be shadowed.
VSS error: VSS_E_PROVIDER_VETO. Code:0x80042306

But this was to be expected. After creating a new volume (I love how easy I can add and remove disk in vsphere!!! too slick) I learned the hard way about block size (mine of course was too small)

This was the error vsphere\veeam threw

CreateSnapshot failed, vmRef “vm-32”, timeout “1800000”, snName “VEEAM BACKUP TEMPORARY SNAPSHOT”, snDescription “Please do not delete this snapshot. It is being used by Veeam Backup.”, memory “False”, quiesce “False”
File <unspecified filename> is larger than the maximum size supported by datastore ‘<unspecified datastore>

After remedying this http://blog.vmpros.nl/2010/02/04/vmware-creating-a-snapshot-for-a-virtual-machine-fails-with-the-error-file-is-larger-than-maximum-file-size-supported-1012384/

So now I am in the process of backing up our Exchange server. I still am researching the whole VSS integration thing, but this post lays it out pretty well


And this cleared up for me the concept of synthetic backups


This also cleared up my question on how I should group my VM’s

We recommend grouping similar VMs (deployed from one template or based on the same OS) to one job to get best de-duplication ratio, in this case with compression enabled (which is the main weapon against white spaces) you’ll save lots of backup storage space.

I also really like the fact that these backups don’t impact the network at all! SAN based backup is awesome!
