Exception of type 'Veeam.Backup.AgentProvider.AgentClosedException' was thrown.

Issue/Error: When we try to backup the VM in veeam backup server, we gets  exception like below,

Exception of type 'Veeam.Backup.AgentProvider.AgentClosedException' was thrown.

Root Cause:

When backup jobs starts and proxy will assign automatically, but assigned proxy doesn't have access for the disk, so unable to access the disk and got failed.

Fig 1 : Backup proxies for HD1 and 2 don't have access permission.

Fig 1 : Backup proxy for HD 2 doesn't have access permission.

Solution:

1. Assign the proxies which has right permission.(Change the proxies to manual in backup job settings and and assign it)

2. Check the proxies that has same IP range as you Hyper-V/Vcenter node, so access using proxies will not get any issues.
