Google Cloud Storage - How do I copy a specific blob version (not the latest) via the CLI gsutil prompt?

I'm trying to understand if there is a way to copy a specific version of a file to a new location e.g. normally I would do the following:

gsutil -m cp gs://my-bucket/foo-bar.py ./

But if there were 30 versions, how would I select the 29th, or any other for that matter?

Noting, I don't wish to restore the old version as a first step either.

I'm aware of the -A option to copy all, but wondering if -v can be used to get the URL first then use the standard statement above against the versioned URL?

Solution

  • You can use #generation at the end of the name, as per the Using versioned objects documentation:

    gsutil -m gs://my-bucket/foo-bar.py#12345 ./

    Note that this is the generation number. You can use gsutil ls -a to list the generations first:

    gsutil ls -a gs://my-bucket/foo-bar.py
