This script creates a backup of all OpenLDAP databases specified in the configuration file(s) and stores them in the specified backup directory. It also allows you to set a retention policy and send an email notification when the backup is complete.

Syntax:

ldap-backup [-c CONFIG_DIR][-r RETENTION_POLICY][-m] CONF_NAME
ldap-backup -h

Each configuration file should have a ".cfg" extension and contain the following variables:

• BACKUP_DIR - the directory where the backups will be stored
• LDAP_SUFFIX_LIST - an array of ldap prefixes to backup
• EMAILFROM - email from which the backup summary will be sent
• EMAILTO - email where the backup summary will be sent to

The script uses the following dependencies:

Note: The script will work without mailutils, but won't be able to send mail after the backup process is done. gzip is required for compressing and archiving the backup files.
