help with back up please

Can anyone please tell me how safe is the following backup script?
Does it really backing up the WHOLE system or just part of it?
I do that with the system running an oracle database.
Will I be able to restore the system in case of a fault?

bak2db.pl

BAK2DB.PL(8)						      System Manager's Manual						      BAK2DB.PL(8)

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] [-v]
       [-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.

       -v
	      Display verbose ouput

       -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 proto-
	      col 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.
