Service panels of online backup
All the configuration information, the current alarm database and the values history (for a restricted time period) can be backed up during operation.
The online mode can be opened from inside the System management. The Database tab contains a button Online backup that opens a further panel with more tabs.
The opened panel contains 4 tabs (DB, Configuration, Configuration, Media) for each host (Host 1 and Host 2).
On Windows system do not use UNC paths for the backup directory. Instead of UNC paths, use drive letters for the network device, which is used as backup directory.
If a UNC path is used, the Data Manager might block during the disc space check when the backup directory cannot be accessed.
With the config entry "autoOnlineBackup" in the "onlineBackup" section of the config file the automatic check for the configuration of the online backup can be activated/deactivated. The check is executed when starting the project (script archiv_client.ctl). The default value is 1 meaning that an automatic check is executed. See the description of the config entry for more details on the entry.
- DB tab: Here you can back up the database manually and independent from the automatic and periodical backup control (Starting backup of the database).
- Configuration tab: Here you back up your project (manually or automatically). A copy of your project directory is created (without the \db and \log directories). Additionally an ASCII Export for following elements is performed: data point types, data points, aliases, original values and config entries. See also: Starting backup of the project.
- Configuration tab: Here you enter parameters such as target path, target medium for your backup, also for an automatic or manual backup (Configuring backups).
- Medium tab: Here, a list of empty files (DB backup and complete Backup) is displayed with the backup date. This enables you to check your automatic backup directly in the project, for example, whether backups have actually been carried out every day (see Protocol of backup actions).
