2.7.1 Backup function
The backup function backs up SSO files and databases. For details on what this function can back up, see 2.7.3 Backup targets and restore targets.
If a backup is executed while a daemon process is running, the processing of that daemon process is interrupted. The daemon process automatically resumes processing when the backup finishes. For details on the daemon processes that are interrupted, see 2.7.4 Daemon process behavior during backup or restore. Daemon processes cannot start or stop while a backup is in progress.
The backup function backs up files first, and then databases. The function can also be used to back up either files or databases. The time required to back up a database depends on the size of that database.
- Organization of this subsection
(1) File backup
If a file backup is attempted while daemon processes are running, the backup function interrupts all daemon processes other than ssospmd, ssoconsoled, and ssotrapd, and then starts backup processing. This means that all the functions provided by the interrupted daemon processes are unavailable during the backup. These functions become available when the backup is completed.
(2) Database backup
If a database backup is attempted while daemon processes are running, the backup function interrupts all daemon processes other than ssospmd, ssoapmon, and ssotrapd, and then starts backup processing. This means that all the functions provided by the interrupted daemon processes are unavailable during the backup. These functions become available when the backup is completed.
