Why my ShrePoint Subsite size is so big? RRS feed

  • Question

  • I have a SharePoint site collection is around 100GB, I need to investigate why is so big. I download a tool from http://spusedspaceinfo.codeplex.com/

    there is a subsite size around 20G. then I take a look at this subsite, I found this subsite has two document libraries, one with 1400 docs, another is 500docs, then I create a view to check each item's file size, then I added it up , it is round 2G total.

    This subsite has no subsite undetneath, the rest documents has NO document inside.

    why this site has 2G documents inside but the site size is over 20G?

  • Not sure this is the reason but if you have versioning turned on and you dont limit the amount of versions this can take a ton of space to.  My first thought would be checking to see if you have versioning turned on with out any limitations

  • > If a document size is 10MB, it has 10 versions, that means SharePoint store around 10* 10 = 100MB only for this document. is that correct?

    1. You need to add an overhead of maybe 60% to each document size for it being stored as an image in a SP database. So that's 16MB per copy.

    2. If you add virtually nothing to the document in each version then, Yes, you have 16*10=160MB, but of course it you add say 50% to say the fifth version then you will have 16*5 + 24*5   = 210MB (or should that example be to the 6th version ...)

  • Thanks for your response.

    This is exactly I am thinking about the possible reason.

    my question is: if the document library turns on version control and it has no limitation. If a document size is 10MB, it has 10 versions, that means SharePoint store around 10* 10 = 100MB only for this document. is that correct?
