Backup

There are four files in the backup directory. This directory is specified when you install Replication Server with ERSSD.

**Table 4-4: Backup directory files**
File name	File definition
<erssd_name>.db	Backup database file
<erssd_name>.log	Backup transaction log
<erssd_name>.db.pre	Previous backup database file
<erssd_name>.log.pre	Previous backup transaction log

An automatic full backup, including both the database file and the transactional log file, is performed at the default or the configured time.

The transaction log is mirrored, providing extra protection for critical data, and enables complete recovery of the transaction log file.

To perform an unscheduled backup, use this Replication Server command:

sysadmin erssd, backup
