3.6.3 Log Server Maintenance
The database should be backed up on a daily basis; the backup should be saved to an
external media, such as Tape, external disk, and network server or similar.
The Log server can be setup to perform a scheduled maintenance, which can run on
specified interval. It is also possible to make the “Maintenance now”.
The Maintenance parameters are setup via the LogClient, but the LogClient itself has nothing
to do with the execution of the maintenance this is totally done by the log server based on the
settings made by the client.
The maintenance is performed by the LogServer, which executes 2 steps: An optional
backup of the database files to a network share, and an optional cleanup old data. Each of
these steps can be disabled independently of each other.
It is recommended to enable the scheduled maintenance with backup and automatic cleanup
enabled. There are several of good reasons for this:
- Keep the database from running out of disk space.
- backup the database to an external disk to ensure data in case of disk crash.
- Keep high performance when querying data from the database.
