I've enumerated all the top level sites and created a script to
backup site collections using stsadm.exe.
I use the syntax;
stsadm.exe -o backup -url http://portal/personal/degaetani -filename
e:\backup\stsbu\degaetani.bak
which works fine for the top level site. I took it one step further
& tried;
stsadm.exe -o backup -url http://brportal/personal/degaetani/Report
Services -filename e:\backup\stssubbu\degaetani_Report_Services.bak
and I got the error;
"The specified URL is not a top-level Web site. The backup and
restore operations work only for top-level Web sites. Enter the URL
for a site to try the operation again.",
which coincides with the Mindsharp, "Sharepoint Admin" courseware,
Mod.13, pg.26. Yes, the enumsubwebs parameter lists all sub-sites
within a site collection, but is that all it does? Are subsites
included when backing up the top level?
