In this section:
Most of the backup and restore processes such as the manual or automated backup configuration and backup destination configuration are the common for the DSC Platforms. The differences for the complete system backup and restore configuration are presented separately for each platform. See Backup Methods.
Backups Web UI
The following image shows the Backups menu in the DSC-SP2000 Web UI.
Backup Types
You can backup the following content on the DSC Platforms.
| Complete Configuration Backup | backs up system and application configuration data This backup type is recommended when the system and application configuration has been affected. |
|---|---|
| System Configuration Backup | backs up system configuration data, such as networking, Network Time Protocol (NTP), static routes, hostname resolutions, users definitions, passwords, and so on. This backup type is recommended when the system configuration has been affected. |
| Application Configuration Backup | backs up application configuration data, such as MTP2, MTP3, SCCP, GTT, SG, and so on. This backup type is recommended when the application configuration has been affected. |
Backup Methods
The following table shows the backup methods as provided in the DSC-SP2000 Web UI. You can create manual or automated backup files and by defining a backup destination you can send these files using electronic transfer (E-mail, FTP, and so on) to a remote server or store the files locally on an internal device.
Refer to the following sections for information about configuring the DSC Platforms supported backup methods.

Manual Configuration Backup
| Note
The SS7 Database Application (SDA) is only supported on the DSC 8000 if you have this application licensed on your system. If, in fact, you have this application licensed on your system and you need a backup of the application, contact Customer Support. |
Automated Configuration Backup
| Automated Backup Configuration |
| Complete System Backup | |
| Restore Backup | Restoring DSC Backup Files |
| Backup Destination | Defining a Backup Destination |
Complete System Restore for DSC 8000 | Complete System Restore for DSC 8000 |
Backup Frequency
For all backup types with the exception of the complete system backup the frequency of backup depends on your system activities and changes to the system and application configuration. It is recommended that you perform regular backups based on these changes. You can use either the automated or manual backup utilities provided in the UI to perform these backups. The estimated time for any of these backups should not exceed 30 seconds.
Prerequisites for Executing Backup and Restore Procedures
Before you start a backup or restore procedure, it is assumed that you have completed the following tasks:
- installed the system and executed the initial configuration procedures
- added the required license keys
added a signed certificate from a certificate authority (CA) (optional)
The system backup will not contain the CA configuration. Before performing a system backup, create a backup of the CA configuration using the dedicated CA backup procedure (refer to Backing up or Restoring CA-signed Certificates).
- performed the required system management tasks such as system date and time configuration, NTP server configuration, password management tasks
- are familiar with the system Ethernet configuration
- logged onto the system as root user
- are familiar with using the Ribbon Signaling System Web UI
have the appropriate USB key for a complete system backup (as required)
A USB Key is only required if the system that you are backing up is a DSC 8000.
Ensuring a Continuous Backup
The disk space designated for local backups depends on the CPU or VM type as applicable. If this space is full, the following precautionary measurements are executed to ensure your continuous backups:
- a warning appears in syslog informing you that your scheduled backup failed, because you have reached the allowed maximum storage for backup files (useful for automated backups)
- a message appears in the Web when you attempt to configure your backup informing you that you cannot perform this task, because you have reached the allowed maximum storage for backup files
