Directory Server perl script for restoring a backup

## NAME

bak2db.pl - Directory Server perl script for restoring a backup

## SYNOPSIS

bak2db.pl -a archivedir \[-Z serverID\] \[-D rootdn\] { -w password \| -w - \| -j filename }  \[-t dbtype\] \[-n backendname\] \[-P protocol\] \[-h\]

## DESCRIPTION

Restores a database from a backup. The Directory Server must be started prior to running this script.

## OPTIONS

A summary of options is included below:

- **-a *archivedir***

  The directory of the archived database.

- **-Z *Server Identifier***

  The server ID of the Directory Server instance.  If there is only  one instance on the system, this option can be skipped.

- **-D *Root DN***

  The Directory Manager DN, or root DN.  If not specified, the script will  search the server instance configuration for the value.

- **-w *password***

  The rootdn password.

- **-w -**

  Prompt for the rootdn password.

- **-j *password filename***

  The name of the file that contains the root DN password.

- **-t *database type***

  The backend database type (default: ldbm database).

- **-n *Backend Name***

  The name of the LDBM database to restore.  Example: userRoot

- **-P *Protocol***

  The connection protocol to connect to the Directory Server.  Protocols are STARTTLS, LDAPS, LDAPI, and LDAP. If this option is skipped, the most secure protocol that is available is used.  For LDAPI, AUTOBIND is also available for the root user.

- **-h**

  Display usage

## EXAMPLE

- bak2db.pl -a /LDAP/backups/20130305/ -D 'cn=directory manager' -w password -n userRoot -P LDAPS

  Note: security must be enabled to use protocol LDAPS.  If LDAPS is not available it will default to next strongest/available protocol automatically.

- bak2db.pl -a /LDAP/backups/20130305/ -Z instance2 -w password -n example -P LDAPI

  ## DIAGNOSTICS

Exit status is zero if no errors occur.  Errors result in a  non-zero exit status and a diagnostic message being written  to standard error.
