Backing-up and Restoring Site
Collection using STSADM (SharePoint Administrative) tool
STSADM is a SharePoint
administrative tool which generally resides in...
Files\Microsoft Shared\web server extensions\12\BIN"
...on a SharePoint 2007 server and
"C:\Program Files\Common Files\Microsoft Shared\web server
...on a SharePoint 2010 environment.
This command is run on
the server, by the people who are member of Administrators group. In
this section we are going to see how this tool can be used to backup a site
collection and restore it back when required. These are general command
formats for abackup and restore of site collection.
Backup -URL <url of the site collection to be backed up> -Filename <location
and name of the file which gets created to store backed up data> -Overwrite
Restore -URL <url of the site collection to restore to> -Filename <location
and name of the backed up file to restore from> -Overwrite
The Overwrite switch is required
to overwrite a file if it already exists on the specified location
during a backup operation and, similarly, overwrite a site collection if it already
exists with same name on the specified URL during restore operation. To
learn about the parameters of this command, follow this link.
Backup -URL http://mktaraliw2k8r2:8081 -Filename \\MKTARALIW2K8R2\SharePointBackupFolder\PrimarySiteCollection.dat
stsadm -o Restore -URL http://mktaraliw2k8r2:8081 -Filename
Please note: Though you
can still use old the STSADM (SharePoint Administrative) tool to perform
backup and restore operations it is not recommended to use this tool (unless you
are forced to use it for backward compatibility) as this tool has been
deprecated and provided in SharePoint 2010 only for backward
compatibility. To learn more about mapping between STSADM and PowerShell
To improve the
performance of backup/restore operations, use a local path to minimize the
latency; if required
you can then move a backed up file to a network location after a backup completes or before
a restore you can move from a network location to a local path and then start
If your SQL
Server version supports
database snapshot (Enterprise and Developer editions) , it is
recommended to use the UseSqlSnapshot parameter with the Backup-SPSite command
for a more consistent backup.
related PowerShell cmdlets are, Get-SPSite, Move-SPSite, New-SPSite,
Remove-SPSite, Set-SPSite, Get-SPSiteAdministration etc.
You need to
make sure the SharePoint 2010 Timer windows service is running before taking
a site collection backup using Central Administration.
maximum size for a site collection backup is 15GB in SharePoint 2007 and
85GB in SharePoint 2010.
