Step 2: Clients
You can configure a new client in the Main selection -> Components -> Topology -> New client.
- Depending on the operating system of a client, either Linux, NDMP, NetWare, Storage (HPE related), UNIX, VMS or the Windows platform can be selected. A client must always be assigned to a location.
- The name of the client to be backed up (target client) is the hostname of this computer on a given network. The target client must have the SEP sesam software installed.
- If there is a name server (DNS) in the network, SEP sesam will automatically select the TCP/IP address. Otherwise it must be entered in the etc/hosts file.
Note that the following screenshots are for reference only. Your configuration may differ depending on OS and client type (physical or virtual).
Name or IPv4-Address: Enter the name of the client – the network hostname of the computer. The name must be resolvable either via DNS or the hosts file. If there is a name server (DNS) in the network, SEP sesam automatically selects the TCP/IP address. Otherwise you have to enter it manually in the etc/hosts file.
Operating system: Select the operating system version of the computer you are adding as a client.
Location: Select the appropriate location from the drop-down list of locations you have configured.
Virtual machine: Select this checkbox if you are adding a VM with SEP sesam backup Client installed. Then the SEP sesam client checkbox will be selected automatically. This option is used to identify the backup client as a VM in a virtual environment. If you are adding a VM host server, do not select this option, but select the Virtualization server below.
Platform : Select the relevant platform: Linux, NDMP, NetWare, Storage (HPE related), UNIX, VMS, or Windows. In most cases, the Operating system is automatically selected when you select the platform. If it is not, select the appropriate version.
Virtualization server : If the client is a VM server, select this checkbox and then select the relevant type from the Virtualization server type drop-down list. This allows, for example, browsing the virtual environment when creating backup tasks.
Access mode: Select the relevant access method for server-client communication.
- CTRL: Access mode, which was the default mode in older versions of SEP sesam.
- SMSSH: Current default access mode. SEP sesam SSH-based control communication. SSL libraries include libmicrohttpd, libcurl, and libopenssl. See also FAQ: access permissions.
- PROXY: Access mode for a hypervisor or other systems without an installed backup client. The data transfer is executed via vendor specific protocols and the client is accessed via the mandatory data mover. For details, see What is a SEP sesam data mover. The following protocols are supported: vSphere (vCenter Server), Citrix Xen Server, Nutanix, NetApp, NDMP and Novell SMS for NetWare 5.1/6.0/6.5.
- VIRTUAL: Access mode for a virtual machine (VM) without an installed backup client, where there is no direct remote access to this VM. Note that VIRTUAL access mode is similar to PROXY, but is specifically intended for managing VMs as clients by allowing configuration of ACLs for VMs. This means that the administrator can allow explicit restore access to a virtual client while preventing access to the hypervisor server. For details on how to configure permissions (ACLs) for clients, see Using Access Control Lists.
- SSH: This communication mode is based on a key-pair operation of the SSH implementation of the operating system used.
- RSH: Remote Shell; this option is deprecated and rarely used.
Notes: Optional additional comment.
|This field is for specifying additional interfaces for SEP sesam Server or Remote Device Server (RDS).
- If there is an additional network for backups, the resolvable and changed DNS name of a second network card of SEP sesam Server can be entered in a new line. If there are several network cards, they need to be known to the DNS, otherwise the connection to SEP sesam Server will fail.
- The network protocols for data transfer can be specified with the common prefixes ftp:// (default), http:// or https://. For each protocol an interface has to be added in the interfaces box separated by single spaces. One interface for the HTTP protocol http://<hostname>:11000 and one interface for the HTTPS protocol https://<hostname>:11088.
- Do not update this client (≥ 4.4.3. Beefalo V2): If you select this option, you can exclude a specific client from the update. This setting applies in general to all possible updates.
- Execution off: If a client needs to be excluded from backup for technical or other reasons, you can deactivate it by checking this option.
|If this option is set, the client will not be backed up until it is unlocked again, even if it is scheduled for backup.
By default, SEP sesam uses random ports that are assigned by the operating system for its data connections. However, if you want to back up a client which is behind a firewall, you need to specify the ports manually. The available options depend on the client type. For details, see Topology: Firewalls.
Tab OS Access
When you configure a new client, you have to enter the credentials as an administrator to access the respective systems. You have to use the format DOMAIN\USER for domain accounts or HOST\USER for local accounts.
The following options may differ slightly depending on your SEP sesam version. As of 5.0.0 Jaglion, create a new credential set to configure your client.
Once all options are set, click Create or Save. Clicking Create will leave the dialog window open, allowing you to quickly configure multiple clients one after another.
A new dialog box then appears asking if you want to create a new backup task for this client. Click Yes to create a backup task or No if you intend to configure your backup later. For details, see Standard Backup Procedure.
Your new client is displayed in the Topology content pane.
Additional tabs in the client properties
Once your client is configured, additional tabs are available for specifying permissions and access. (Double-click the client to open its properties.)
On the Permissions tab, you can add the appropriate permissions for your client. For details, see Using Access Control Lists.
When configuring clients to be backed up by specific task types, you need to specify some additional settings. An additional access tab is available for some task types, such as: Citrix XEN, Micro Focus Open Enterprise Server (formerly Novell OES), MySQL, NetApp, PostgreSQL, Proxmox, RHV, VMware.
- For example, if you configure vCenter Server as a SEP sesam Client, you need to specify the vCenter credentials with the highest administrator privileges and select the appropriate data mover. For more information on specific task types, see the corresponding wiki articles under Extensions.
- Or, for Micro Focus OES or NetWare server backup, you must specify the login data for the eDirectory and select the appropriate data mover.
For more information on specific task type, see the corresponding wiki articles under Extensions.
|(VMs only) If you intend to back up multiple VMs, you can automate the process by automatically generating tasks for VMs that are connected to the same host. You can also automatically create clients for VMs to which the created tasks and ACLs can be assigned. It is recommended to use these features when a new hypervisor is added and many new VMs need to be backed up. For details, see Automating Backup Process.
