does it ever worked  or its a new config?

What is the Transport mode that you are using? NBD or SAN?

did the user name and passwd that you provided for offhost backup is valid? expired ?

I have seen this for two situations - usually where san has been selected (snapshot optins or VMWare options, depending on if this is a Flashbackup-Windows or VMWare policy) but the datastores cannot be seen over the fibre, and also when the account used for access to the vCemter Server (Media and Device Management - Credentials - Virtual Machine Servers) has had its password changed or been disabled.

Also check that the VMWare backup host selected it correct and the one that has the datastores mapped to it (if you are using san)

If you are using nbd (backup over the LAN) and you get this error it would normally be the account that is your issue

Thanks for your reply.. Sorry I am very new to VM backups, not sure about the transport types.

However I have checked the following  article on different  transport types

Could you please guide me how to check the same ?

This policy has worked before and the other VM backups are going fine, so I don't think it's an issue related with credentials for off-host backup.

Hi Mark,

Thanks for reply. Datat store is SAN.Looks fine when I am checking the same from Vsphere client.

Now checking the VMWare backup host & the mapped data store for it.

Hi Tanmay,

You must have some default permissions for the restoration to work for a VM.

This link would be useful :

Use transprt mode as NBD, in this case you don't need to make the datastore online on the VM host.
