A backup directory can be configured for online and offline backups. Both are based on a daily directory structure. An online backup directory configured via the properties Backup Directory on Server (Online) (COOSYSTEM@1.1:dareabackupdir) or Path to Backup Directory on Server (Online) (COOSYSTEM@1.1:dareabackupremdir) means that contents will be backed up in the directory during normal operations. Additionally, this kind of backup directory can also be synchronized with the configured area paths. On the other hand, an offline backup directory configured via the property Path to Backup Directory on Server (Offline) (COOSYSTEM@1.1:dareaofflinebackupremdir) will not be used during normal operations. This backup directory will only be used for manual backup tasks.
When using the options synctobackup or syncfrombackup of the action Cleanup Content Areas in the tool fscadmin, the configured area paths can be synchronized with the backup directory. Using the option cleanupbackup, a cleanup of the backup directory can be started. The cleanup is based on file system operations meaning that each file in the backup directory which is no longer available in one of the configured area paths will be deleted. cleanupbackup only makes sense when the operation is executed after removing unreferenced files on the configured area paths using the action cleanup.
Using the option offlinebackup with synctobackup, syncfrombackup, or cleanupbackup means that the configured offline backup directory is used for the specified operation instead of the online backup directory.
The tool cleanbackup removes files from the backup directory by using the deletion log generated during cleaning up an MMC Area. This tool takes the parameters root, which specifies the path of the backup directory to be cleaned up and days to define the minimum number of passed days since the deletion of a file in the MMC Area for deleting it in the backup directory, too.
