you can, if you wish to, split Global Config and Pool Config backup to two separate xml files:
If you prefer to back up each of the two levels of settings to a separate configuration file (.xml file), run the command two times, with the following modifications:
•For the /level attribute, specify only one of the two setting levels (global or pool) each time you run the command.
•For the /configfile attribute, specify a different, unique file name for each level.

I use ExpressMaint utility (found it thanks to you!) with command line switches for SQL dbs backup http://www.sqldbatips.com/showarticle.asp?ID=29

I've placed service account for that scheduled task into RTCUniversalReadOnlyAdmins group (so config backup runs ok) and local Administrators group on OCS box (so SQL dbs backup can run). Is that correct?

Btw, is there little spelling mistake in file names here:
"You take this code and save it as storemaint.sql. Then run the following code:
“C:Program Files (x86)Microsoft SQL Server90ToolsBinnsqlcmd.exe” -S .RTC -i c:ocsbackupexpressmaint.sql"

Should the file name storemaint.sql be expressmaint.sql?
