The Rsync over SSH backup method connects the target server with SSH and executes the rsync UNIX command to copy the data to the remote server. SPS authenticates itself with a public key — password-based authentication is not supported.
|
|
Caution:
The backup server must run rsync version 3.0 or newer. |
To create a backup policy using Rsync over SSH
-
Navigate to Policies > Backup & Archive and click 
in the Backup policies section to create a new backup policy.
-
Enter a name for the backup policy (for example, config-backup).
-
Enter the time when the backup process should start into the Start time field in HH:MM format (for example, 23:00).
You can add the start time for additional backup processes.
|
|
Caution:
When specifying an additional start time, ensure that the previous backup process finishes before the new backup process starts. |
-
Enter the IP address or the hostname of the remote server into the Target server field (for example, backup.example.com).
Use an IPv4 address.
-
Select Rsync over SSH from the Copy data from PSM radio buttons.
Figure 59: Policies > Backup & Archive > Backup policies — Configuring backups using rsync
-
Enter the username used to log on to the remote server into the Username field.
-
Click 
in the Authentication key field. A popup window is displayed.
-
Generate a new keypair by clicking Generate or upload or paste an existing one. This key will be used to authenticate SPS on the remote server. The public key of this keypair must be imported to the remote server.
-
Click in the Server host key field. A popup window is displayed.
-
Click Query to download the host key of the server, or upload or paste the host key manually. SPS will compare the host key shown by the server to this key, and connect only if the two keys are identical.
Figure 60: Policies > Backup & Archive > Backup policies — Configuring SSH keys
-
Enter the port number of the SSH server running on the remote machine into the Port field.
-
Enter the path to the backup directory on the target server into the Path field (for example /backups).
SPS saves all data into this directory, automatically creating the subdirectories. Backups of audit-trails are stored in the data, configuration backups in the config subdirectory.
-
When your SPS instance is a node in a cluster, select Include the Cluster Node ID in the path. This ensures that the ID of the node is included in the path of the relevant directory, which is required to prevent cluster nodes from backing up data to the same location, and so overwriting each other's data and resulting in data loss. In addition, having the node's ID in the directory name also enables easy identification.
|
|
Caution:
Hazard of data loss
Unchecking Include the Cluster Node ID in the path when your SPS is a node in a cluster can result in data loss if you have configured configuration synchronization across your cluster nodes. |
-
To receive e-mail notification of the backup, select the Send notification on errors only or the Send notification on all events option. Notifications are sent to the administrator e-mail address set on the Management tab.
To include the list of files in the e-mail, select Send notification on all events and enable the Include file list option. However, note that if the list is very long (for example, SPS stores over 20000 audit trails), the SPS web interface might become unaccessible. In this case, set the Maximum number of files in notification lower. After this number has been reached, file names will be omitted from the notification.
NOTE: This e-mail notification is different from the one set on the Alerting & Monitoring tab. This notification is sent to the administrator's e-mail address, while the alerts are sent to the alert e-mail address (see Configuring system monitoring on SPS).

To assign the backup policy to a connection, see Creating data backups.
The Copy data to a remote server using SMB/CIFS backup method connects to a share on the target server with Server Message Block protocol. SMB/CIFS is mainly used on Microsoft Windows Networks.
When deployed from the Azure Marketplace, you can use Azure File storage shares for Backup and Archive Policies. This is very useful as you can change the quota for the file storage dynamically, so the cumulative size of the audit trails is not limited to the OS disk size. You can set up this share as normal SMB shares in your Backup and Archive policies. You can obtain the parameters for the policy from the Azure portal.
NOTE: Backup and archive policies only work with existing shares and subdirectories.
If a server has a share at, for example, archive and that directory is empty, when the user configures archive/scb1 (or similar) as a backup/archive share, it will fail.
|
|
Caution:
When you try to create backups and archives from SPS to NetApp devices using the CIFS protocol, the operation may fail with a similar error message: /opt/scb/mnt/14719217504d41370514043/reports/2010": Permission denied (13) '2010/day/' rsync: failed to set times on.
To overcome this problem, grant the SPS user "Full Control" access rights to the CIFS share on the NetApp device. |
-
Navigate to Policies > Backup & Archive and click in the Backup policies section to create a new backup policy.
-
Enter a name for the backup policy (for example, config-backup).

-
Enter the username used to log on to the remote server into the Username field, or select the Anonymous login option.
Usernames can contain space.
-
Enter the password corresponding to the username into the Password field.
NOTE: SPS accepts passwords that are not longer than 150 characters and supports the following characters:
-
Enter the name and directory path of the share into the Share field. Use the following format:
share_name/path/to/directory
You can use backslashes and forward slashes as well.
SPS saves all data into this directory, automatically creating the subdirectories. Backups of audit-trails are stored in the data, configuration backups in the config subdirectory.
-
Enter the domain name of the target server into the Domain field.
-
Select which SMB protocol to use when SPS connects to the server in the Protocol version field. Servers are usually backwards compatible with earlier protocol versions (for example, a server that supports version 2.1 supports versions 2.0 and 1.0 as well).
-

The Copy data to a remote server using NFS backup method connects to a shared directory of the target server with the Network File Share protocol.
NOTE: Backup and archive policies only work with existing shares and subdirectories.
If a server has a share at, for example, archive and that directory is empty, when the user configures archive/scb1 (or similar) as a backup/archive share, it will fail.
The version of NFS used is automatically detected. All versions of NFS, up to and including NFS version 4 protocol, are supported.

SPS saves all data into this directory, automatically creating the subdirectories. Audit-trail backups are stored in the data, configuration backups in the config subdirectory.
-
The remote server must also be configured to accept backups from SPS.
Add a line that corresponds to the settings of SPS to the /etc/exports file of the backup server. This line should contain the following parameters:
-
The path to the backup directory as set in the Export field of the SPS backup policy.
-
The IP address of the SPS interface that is used to access the remote server. For more information on the network interfaces of SPS, see Network settings.
Use an IPv4 address.
-
The following parameters: (rw,no_root_squash,sync).
Example: Configuring NFS on the remote server
For example, if SPS connects the remote server from the 192.168.1.15 IP address and the data is saved into the /var/backups/SPS directory, add the following line to the /etc/exports file:
/var/backups/SPS 192.168.1.15(rw,no_root_squash,sync)
-
On the remote server, run the following command:
exportfs -a
Verify that the rpc portmapper and rpc.statd applications are running.

To create a configuration backup, assign a backup policy as the System backup policy of SPS.
TIP: To create an immediate backup of SPS's configuration to your machine (not to the backup server), select Basic Settings > System > Export configuration. Note that the configuration export contains only the system settings and configuration files (including changelogs). System backups includes additional information like reports and alerts, and also the connection database.
When exporting the configuration of SPS, or creating configuration backups, always use encryption. Handle the exported data with care, as it contains sensitive information, including credentials. For details on encrypting the configuration, see Encrypting configuration backups with GPG in the Administration Guide.
To encrypt your configuration backups, see Encrypting configuration backups with GPG.
