Backup and Restore Options for Windows SharePoint Services
There are several methods you can use to back up and restore data for
Microsoft Windows SharePoint Services. Each of these methods allows you
to back up and restore data, but each method acts at a different level
of granularity and may require different permissions. You can back up
and restore data for Windows SharePoint Services by using the following
methods:
·Use the Microsoft SQL Server 2000 tools to back up the databases.
You can use the backup tools included with SQL Server 2000 to get a
full-fidelity, complete backup of the databases used by Windows
SharePoint Services on your server or server farm. When you use this
method, you back up and restore the entire configuration database and
each content database on your server or in your server farm. You can
then restore any or all of these databases. You must be running SQL
Server 2000, not Microsoft SQL Server Desktop Engine (Windows) 2000
(WMSDE), to be able to use this backup method, and you must be an
administrator on the local server computer that is running SQL Server.
This option is the most secure of the backup and restore options
described in this topic.
For more information about backing up databases in SQL Server, see
"Backing Up and Restoring Databases by Using the SQL Server 2000 Tools"
in the Windows SharePoint Services Administrator's Guide and the Help
system for SQL Server 2000.
·Use the Stsadm.exe command-line tool to back up individual site
collections.
You can get a full-fidelity, complete backup or restore of an entire
site collection by using the Stsadm.exe command-line tool with the
backup and restore operations. This method of backing up and restoring
data does not require SQL Server 2000. However, you must still be an
administrator on the local server computer that is running Windows
SharePoint Services in order to perform this method of backing up and
restoring.
For more information about backing up site collections by using the
Stsadm.exe command-line tool, see Backing Up and Restoring Web Sites.
·Use the Microsoft SharePoint Migration Tool (smigrate.exe) to back
up individual sites and subsites.
You can back up and restore individual sites or subsites by using the
SharePoint Migration Tool. This method is not full-fidelity; you may
lose some customizations or settings in the process. For example,
security settings for the site, such as user membership in site groups,
cannot be restored when you use the SharePoint Migration Tool. However,
with this backup method, you do not need to be an administrator on the
local server computer. Any member of the Administrator site group for a
site or subsite can use this method.
Running Microsoft SQL Server tools frequently (such as once a week) can
be costly to an organization. Also, these tools support backup and
restoration at the database level only, making it impractical to
restore single sites or site collections. The Stsadm.exe command-line
tool supports complete backup and restoration at the site-collection
level, including security settings. It is ideal for targeted backups
and is less costly to run.
A practical and effective backup strategy for your Windows SharePoint
Services installation is to use both of these tools. At longer
intervals, such as monthly, back up your entire set of databases using
the Microsoft SQL Server tools. At shorter intervals, such as weekly,
run Stsadm.exe to back up just those site collections that have
changed. This will facilitate quick recovery of lost items with a
minimum of space usage, while the Microsoft SQL Server tools backups
are available for large-scale disaster recovery.
