SSIS Package to Back Up SSAS Databases
There are a couple of different posts and blog entries out there that discuss backing up SSAS databases using various techniques such as AMO, SSIS, etc. I recently created an SSIS package to do the same thing, and I think it's a little bit simpler than some of the other solutions out there.
The basic design of the package is to use a ForEach Loop container to loop over the list of databases on a given SSAS server (versus using AMO or some other method of getting a list of databases) and then using an Analysis Services DDL task with an XMLA script that calls for a backup of the current database.
