Invalid bucket name in Google Cloud Storage when backup Google App Engine datastore

Question

I have a few python applications running in Google App Engine, and using datastore as storage.

I'm referring to https://cloud.google.com/appengine/docs/adminconsole/datastoreadmin#backing_up_data

When you choose Cloud Storage, you are prompted for the bucket name where the backups are to be stored, in the format /my_bucket_name. You can optionally specify the bucket name suffixed with a directory structure (e.g., /bucket_name/backups/backup1): If those folders don't already exist, they will be created. Note: In older versions of App Engine, users were required to use the format /gs/bucket_name. While the prefix /gs/ will continue to work, it is no longer required.

Hence, I try to supply /my_bucket_name as Google Cloud Storage bucket name.

However, when I click on Backup Entities, I get error

Unsupported filesystem: my_bucket_name

---

I try another name /gs/bucket_name

I get

Bucket "bucket_name" not accessible

I was wondering, how can I provide a valid bucket name for Google Cloud Storage, in order to backup my datastore?

Answer 1

I had the same problem I solved as follows:

I add to my bucket permissions this entry: [e-mail] with write access.

I entered the name of my bucket without the "/" before, even if it is not what is stated in the documentation. In your example, it would simply write my_bucket_name.

The copy was successfully executed.

Answer 2

You have to create a bucket in your project before trying to perform the backup. To create a bucket, go to Storage menu and select Browser option.
