I was using google cloud platform to host a ckan based website. The website had a file library with about 5 gigs of documents. Our project got put on hold and I removed billing on the website about 8 months ago. Now we are trying to migrate the data, but when I look at the project in Google Cloud Platform, there are no compute instances, buckets or files under the various storage modules. I cannot find the 5gigs of files we uploaded and filed by various categories on the ckan website. What could have happened to them? I'm not very experience with this platform and a bit confused. Is there any way for me to recover my data?
