Powershell script to backup My Sites!

This one rocks too!

 $ssppath = "http://sharepoint2007:100/personals"

$out = stsadm -o enumsites -url $ssppath
$out = [xml] $out

ForEach ($web in $out.Sites.Site )
{
$url = $web.url

$name = "c:" + $url.SubString($url.LastIndexOf("/")+1).replace(":","") + ".bak"

write-host "stsadm -o backup -url $url -filename $name -overwrite"
stsadm -o backup -url $url -filename $name -overwrite

}
