I have a non-public website (I may be able to give you access if that would help) that has been running for several years. It is not a particularly large site if you check the size of a routine backup (I get a file size of only 2-3MB on the Backup). However when I run All-in-one Migration Pro to export the site I get a file size of 10GB!
Most of the content is routine and should not be contributing to such a large size. The only thing that I can think of is the images that are maintained in the NextGen image gallery (although there could not be more than 300-400 or so, however some of them can be as big as 7, 8 or 9MB in size; those are large but they cannot be causing such a large backup size). Nevertheless they should not be contributing to such a massive size of 10GB.
I tried configuring NextGen to optimize the size of all future uploaded modules, however those that were already uploaded I think stay the full size. Is there anything I can do with older NextGen files?
What can I do to downsize the website 10GB size? Are there any tools that can help me narrow down the file size to individual components? Any other suggestions?
