BACKUP:[edit]

- In the gear icon, click Backup. The Immediate Backup dialog box opens.
- Select the source server from the drop-down list.
- Select whether to run a Full or Incremental backup.
Note:[edit]
- A full backup process backs up all the information needed to restore mailboxes, including the LDAP directory server, database, index directory, and message directory for each mailbox.
- An incremental backup process backs up the LDAP directory server and gathers all the redo log transactions written since the last incremental backup or the last full backup, if this is the first incremental since the last full backup.
