c# vss - volume shadow copy problem. we are using the open source AlphaVss library. now we have a problem with it: if we have multiple volume shadow provdiers, (for example the normal micorsoft vss provider and the acronis vss proivider and a hardware vss provider). in this case, we cant access the sql writer that works with the micorsoft privoider. in other words: we can not select the provider we want to use. we have a ugly workaround ... we remove all providers except the microsoft privider from the registry and the restart the vss service. then it works ... but we must find the proper solution. you must have expirence with the vss technique, best if you know the alpha vss library. you must have a testenviroment with multiple providers, and make a demo app that showes how to solve the problem. you must deliver a finished and tested application. (incl source code) if you place a bid for this, write me what expirience you have with vss.
