Full Backup Process

The full backup process goes through the following steps to backup the mailbox, the database, the indexes, and the LDAP directory:

1.	Backs up the global system data including system tables and the local config.xml file.

2.	Iterates through each account to be backed up and backs up the LDAP entries for those accounts.

3.	Places the account’s mailbox in maintenance mode to temporarily block mail delivery and user access to that mailbox.

4.	Backs up the mailbox.

a.	Creates MySQL dump for all data related to that mailbox.

b.	Backs up the message directory for that mailbox.

c.	Creates a backup of the index directory for that mailbox.

5.	Returns that account’s mailbox to active mode and moves on to the next one.

6.	Backs up the LDAP directory.

Full backup is usually run asynchronously. When you begin the full backup, the label of the ongoing backup process is immediately displayed. The backup continues in the background. You can use the zmbackupquery command to check the status of the running backup at any time.

Backup files are saved as zip files without compression. To change the default zip option, see Appendix A Command Line Interface, zmbackup section.
