Configuring Storage : Configuring Snapshots and Proxy Backup : Configuring Proxy Backup for a LUN
  
Configuring Proxy Backup for a LUN
The proxy backup feature enables backup integration directly from the data center. The Core clones the snapshot specified for data protection and mounts the cloned LUN on the proxy server. The backup software then communicates with the proxy server to perform the backup.
You can configure data protection settings for the current LUN in the Setup tab within the Snapshots tab of the Configure > Manage: LUNs page.
The procedure varies slightly, depending on the type of LUN (Windows or VMware).
Prerequisites
To configure proxy backup settings for the current LUN, you must specify either VMware or Windows for the client type in the General Settings panel in the same tab as the Proxy Backup panel.
Caution: Because each backup operation takes approximately two minutes to complete, enabling the hourly option for more than 30 LUNs can result in an increasing number of nonreplicated snapshots on Edges.
To configure proxy backup options
1. Choose Configure > Manage: LUNs to display the LUNs page.
2. From the list of configured LUNs, click the desired LUN to display controls and settings.
3. Select the Snapshots tab.
4. Within the Snapshots tab, select the Configuration tab.
5. In the Proxy Backup panel, configure the settings using the controls in this table.
Note: Hints are available to help you specify regular expressions for VM names. To view the hints, hover over the phrase (regex) after the name field.

Snapshot Mount Category
Select from the drop-down menu the snapshot mount category: Weekly, Daily, or Hourly.
Note: To successfully mount a snapshot, you must schedule a policy that includes a matching category.
Proxy Hostname
From the drop-down list, select the hostname of the machine that will mount the cloned LUNs on the storage array to perform the backup the data. To add a new Proxy Hostname, click Add New.
Proxy Host Storage Group
Specify the storage or initiator group for the snapshot (backup) host. This is the group that you defined on the backend storage array that grants access to the snapshot host. Once Core exposes a snapshot as a cloned LUN, it makes the cloned LUN available for reads and writes to the proxy host in the data center. This proxy may host the registered VMs in the case of VMware LUNs or may have the cloned LUN added as a mount point for NTFS LUNs. The backup software communicates with the proxy host to back up the data.
Proxy Host Storage Group is different than a storage group in order to separate LUNs from cloned LUNs being used for snapshots. This way, the Core can only see and project live LUNs to the Edge.
Caution: If you are using a Dell EqualLogic storage array, you must configure the snapshot access policy on the storage array itself to ensure access for the proxy host.

Data center Name
(VMware clients only)
Optionally, specify a data center for VMware-based backups.
Include VMs
(VMware clients only)
Optionally, specify by regular expression the names of the VMs included in the snapshot to be included in the backup. For example:
•  To include VMs whose names begin with a specific prefix: ^2k3
•  To include VMs whose names end with a specific suffix: ova1$
•  To include VMs whose names start with a digit: ^\d
•  To include VMs with a specific name: 2k3vm_15g_ova1
•  To include VMs whose names have a particular format: 2k3v._15g*.ova
•  To include VMs whose names have a particular format: 2k3v.*ova
Exclude VMs
(VMware clients only)
Optionally, specify by regular expression the names of the VMs included in the snapshot to be excluded from the backup. For example:
•  To exclude VMs whose names end with a specific suffix: ova1$
•  To exclude VMs that have a specific name: 2k3vm_15g_ova1
Include ESXi Hosts
(VMware clients only)
Optionally, specify by regular expression the ESXi hosts to be included. For example, to include an ESXi host with a specific name: dcESXi1c_backup
Exclude ESXi Hosts
(VMware clients only)
Optionally, specify by regular expression the ESXi hosts to be excluded. For example, to exclude an ESXi host whose name has a particular format: dcESXi1.*_backup
