Choose whether to use continuous or manual logical-log backup:
With automatic backup, the logical log is backed up periodically, for example, at 20:00 every day. All full logical-log files are backed up at this time. However, the problem with automatic backup is that you might forget to start the backup in time and the logical log completely fills.
