Restoring Data
Move the zip archive to another machine or removable medium. If possible,
encrypt the archive (do not use the private keys stored in your CMS server's
database, since they may not be available when you need to restore the data). If you
copy the archive to removable media such as tape or CD, make sure the copy is
kept in a limited-access, locked area.
Restoring Data
The purpose of creating back up archives, of course, is to allow you to restore a
previous state of the CMS server instance after a hardware or software failure
corrupts your current state. The restore tool allows you to recover all or part of the
configuration that was backed up. For example, you can use the tool to restore just
the internal database of a CMS server instance.
A special case, automatic restore, allows you to completely restore the
configuration from the latest backup archive quickly and without interaction.
Before You Restore Data
Before you can restore from a backup archive, the archive you want to use has to be
available on a disk accessible from the server instance directory. If you want to use
the automatic restore feature, you should put the archive in the output directory
where
originally created it (
on Windows NT or
on
cmsbackup
C:\Temp
/var/tmp
UNIX).
Note the full path name to the backup archive; in the instructions later it will be
referred to as
. For example, on a UNIX system, the
<archive_path>
might be
<archive_path>
.
/var/tmp/CMS_cmsdemo_BACKUP-19991115093827.zip
You can use the word
instead of a path name to indicate the location of
automatic
the backup archive. If you use
, the restore tool will read the file
automatic
to find the path name of the archive. This file is created by
logs/latest_backup
and contains the name of the last archive created. Note that
cmsbackup
automatic
always causes all data to be restored: you will not be able to select only a subset of
the data.
If you moved the zip archive to another machine or removable medium, copy it
back to the local file system. If you encrypted the archive, decrypt it before you try
to restore the data.
