The usage of Microsoft IT Site Delete Capture Feature 1.1

When try to recover a sub-site by the method of the instruction of document which is "stsadm -o store". I received the error message "Your backup is from a different version of Windows Sharepoint Services and cannot be restored to a server running the current version." I almost gave it up.
I got back to test it again for draft my mutiple levels recovery precedure. It looks the microsoft existing solution just missing the part of site and site collection recovery which is what MS IT Site Delete Capture do.
There's just one difference on it, i.e. Site-collection and Sub-site.

1. For Site-collection which was created by central administration. Use the command:
   "stsadm -o restore -url http://www.yoursite.com/sites/deletedsitecollectionname -filename deletedsitecollectionname"
2. For Sub-site which was created by user site action. Use the command:
   "stsadm -o import -url http://www.yoursite.com/deletedsubsitename -filename deletedsubsitename

For PWA workspaces or other same level site, you want to use the same operation with sub-site.

For lower level such as document library, list and items, the 2 level recycle bin take over the recovery.

For higher level such as web application, farm. you probably need operate the sharepoint central administration with database tools together.
