Hello everyone!
I will share with you about the single-server system and cold backup deployment mode.
Deployment of a Single-Server System
A single-server system is easy to deploy and cost effective. However, it is not vulnerable to risks and not good at high availability. If a high availability solution is required, you are advised to use the U2000 high availability system deployment solution.
The single-server system is deployed on Windows, Solaris, or SUSE Linux, and supports single-server multiple-client networking schemes. The clients and the server are connected by means of LAN or WAN.
Cold Backup Solution
In the cold backup solution, two single server U2000 systems with the same version, deployment domain, language, OS type, server time, and time zone are deployed. One system is run on the primary site and the other is run on the secondary site.
In normal conditions, the primary site provides the network management functions. The network management process and maintenance tool on the secondary site are standby while the database is running. The primary site backs up the network management data periodically, and the secondary site obtains the backup file from the primary site at regular intervals.
If the U2000 on the primary site fails, the U2000 on the secondary site starts immediately to provide network management functions.
The backup object is the entire database, including the custom data at the U2000 side (excluding the custom options of the system), network layer trail data, NE-side configuration data, alarm data and performance data. In addition, a backup is created for the structure of the entire database, all database tables (including the system tables and the user tables), table structure, and stored procedures.
NOTE:
The personal information (including personal name, phone numbers and addresses)on the U2000 and all user names and passwords are also backed up. Therefore, you are obligated to take considerable measures, in compliance with the laws of the countries concerned and the user privacy policies of your company, to ensure that the personal data of users is fully protected.
The following data is not backed up when you back up the U2000 database:
The data that is not saved at the NE side, that is, the data that cannot be uploaded.
The custom options of the system. For example, font, color setting, and audio setting.
The fast restoration scheme for the U2000 cold backup system supports manual and automatic backup and restoration. If you use manual backup and restoration, you need to manually start the backup or restoration task each time. If you use automatic backup and restoration is used, you only need to configure a scheduled backup and a scheduled restoration task. The automatic backup and restoration is recommended.
Automatic backup and restoration scheme: To automatically back up and restore data, you need to configure scheduled backup tasks on the primary site and automatic restoration tasks on the secondary site. The process is as follows:
1. On the secondary site, install a single server U2000 whose version, deployment domain, language and database username are the same as those on the primary site.
2. Configure scheduled backup tasks on the primary site. The backup files are generated through backup modules and stored on the primary site.
3. Configure scheduled restoration tasks on the secondary site. Obtain the backup files through SFTP from the primary site and restore the files on the secondary site.
4. When the primary site malfunctions, start the U2000 on the secondary site to fast restore the U2000.
Manual backup and restoration scheme: The manual backup and restoration scheme requires a cold backup tool to back up and restore data. The process is as follows:
1. On the secondary site, install a single server U2000 whose version, deployment domain, language and database username are the same as those on the primary site.
2. Use a cold backup tool to back up the U2000 data on the primary site as backup files and store the files on the primary site.
3. Copy the backup files from the primary site to the secondary site, and use the cold backup tool to restore the files on the secondary site.
4. Start the U2000 on the secondary site.
