In order to ensure that all critical data is backed up and secure, all of the following should be backed up on a regular basis.
Mail Data Backups
The Maintenance > System > Mail Data tab allows the backup and restore of all mail data, including system quarantine, email users’ personal quarantines, user preferences, archived email, and server mode webmail mailboxes. It also provides a monitor of the status of any backup or restoration that is currently in progress.
It is recommended that a full backup be done at weekly intevals, with incremental backups being done every weekday.
System Configuration Backups
In Maintenance > System > Configuration > Backup Configuration, there is an option to back up User configuration and IBE data, along with the configuration.
If the configuration is changed on a regular basis, it highly recommended to schedule backups of the configuration to a remote FTP/SFTP server under Maintenance > System > Configuration > Backup Configuration > Scheduled Backup > Remote backup.
Log Backup
To back up the logs, go to Log and Report > Log Settings > Remote Log Setting, and configure the logs to be sent to a remote server.
Under Logging Policy Configuration, for Gateway and Transparent mode it is not necessary to select:
POP3 server event
IMAP server event
All other options should be selected.
However, for devices in server mode all options should be selected in this section.
In all cases select:
AntiVirus Log
AntiSpam Log
History Log
If IBE/Secure Mail is being used then "Encryption Log" should be enabled.
