using Google Cloud for virtual tapes

At a customer I have to somehow move the backups into Google Cloud (the 
company moves everything there).

Does anyone already combine that with amanda somehow?

They forwarded me this:

I could think of using amvault to *copy* vtape content there.

And I find "Cloud Storage FUSE" which allows to mount such a storage bucket.

Does anyone here have experience with this and Amanda backups?

thanks, regards, Stefan
