All of the data to be backed up is copied to the temporary backup directory. After
all of the data has been copied, the script archives the entire backup directory into a
compressed archive using
<server_root>/bin/cert/tools/zip
once the zip archive is created.
What the Backup Tool Does Not Do
The
script backs up only configuration and data related to a single CMS
cmsbackup
server instance. You may need to back up other files to recover from a failure
completely, depending on the nature of the failure. For example, if some entries in
your configuration Directory Server become corrupted then the data backed up by
is sufficient to restore the directory to a previous state. If, however, you
cmsbackup
suffer a catastrophic disk failure, you will probably have to reinstall or restore
Certificate Management System, Netscape Console, and Netscape Directory Server
binaries and related tools before you use
configuration.
The following is a list of items which may be part of your overall CMS deployment,
but which are not backed up by
•
Other instances of CMS servers in the same server root
Each instance has a copy of the cmsbackup script that backs up only data
related to that instance.
•
External PKCS#11 module data
If you use an external PKCS#11 device for key storage, make sure you follow
the vendor's instructions for backing up its data whenever you back up your
CMS server. It may be possible to extend the
Perl scripts to include this data in the archives used by the
CMSRestore.pl
CMS backup tools.
•
Server binaries, libraries, and tools
These files do not change after installation, and are not backed up. To restore
these files, you can install the software again from the original media. You can
also use a more generic disk backup tool to archive the contents of all
directories beneath the server root.
