10.1 Backup and Restoration of Admin Servers
This section describes how to operate the backup and restoration of the admin server of ServerView Resource Orchestrator Cloud Edition.
Backing up the Admin Server
The two methods of backing up the Management Server are shown below.
With either method, backup can be performed by executing one command (the rcxmgrbackup command).
For details on the rcxmgrbackup command, refer to "6.6 rcxmgrbackup" in the "Reference Guide (Command/XML) CE".
- Offline Backup
The manager of this product is stopped and then resources are backed up. A backup is taken at the following times:
- When installation of this product has completed
When using an offline backup, backup of the following resource is not performed:
- Audit log
- Network device configuration file
- Online Backup
Resources are backed up without the manager of this product being stopped. Backing up periodically is recommended for online
backups.
To save time when restoring configuration information at operation, take an online backup if configuration information is to be updated.
When using an online backup, backup of the following resources is not performed:
- Dashboard Information
- Operational Status Information
- Audit Log
- Application Information
- Definition File
- Some L-Platform Management Settings
- Tenant Management and Account Management Settings
- Operational Status Server List Settings
- CMDB Agent Event Log Output Settings
- Network device configuration file
Online backup uses the PostgreSQL Point-In-Time Recovery (PITR) mechanism.
There are two online backup methods, each with a different database collection range, as follows:
- Base Backup
Base backup is the backup of the entire database cluster (file group in which database data is recorded). A base backup is taken
by executing the rcxmgrbackup -base command.
Refer to "Base Backup" in "10.1.3 Online Backup of the Admin Server" for details.
- Differential Backup
With differential backup, the contents of updates to the database are output to multiple files in 16 MB-sized lots.
These files are called Write-Ahead Logging (WAL) files.
