Sometimes it is useful to run a manual backup outside of the normal schedule:
The validity of the data backup is determined by the state at which the database was backed up. If your system uses a snapshot-based backup script, the backup can be run at any point in the day — regardless of system activity. If you are not using a snapshot-based backup, you must ensure there are no user or phantom processes running on the system.
To run the backup process in foreground:
- Log in as root
- At the root prompt (#), run:
/bin/save
- When the backup has completed, you will return to the root prompt (#)
To run the backup process in background:
- Log in as root
- At the root prompt (#), run:
at now /bin/save
- Hold Control and d (Ctr-d) to submit the background job
- Review the /tmp/backup* files to check the backup status
