I want to sync a local directory to a bucket in Google Cloud Storage. I want to copy the local files that do not exist remotely, skipping files that already exist both remote and local. Is this possible to do this with GSUtil? I cant seem to find a "sync" option for GSUtil or a "do not overwrite". Is it possible to script this?
I am on Linux (Ubuntu 12.04)?
Using rsync, you can copy missing/modified files/objects:
gsutil -m rsync -r <local_folderpath> gs://<bucket_id>/<cloud_folderpath>
Besides, if you use the -d option, you will also delete files/objects in your bucket that are not longer present locally.
Another option could be to use Object Versioning, so you will replace the files/objects in your bucket with your local data, but you can always go back to the previous version.
