Are you 100% certain that DB.xbstream is in fact a proper xbstream file?

`$ dd if=DB.xbstream bs=16 count=2`  
This should return something like the following:  
`XBSTCK01Pworld/countrylangu`

In this example, ‘world/’ is the name of a schema, and ‘countrylanguage.ibd’ is a table inside that db.

Feel free to download and test with an xbstream from our training bucket:

I used the following command to create xbstream file:  
xtrabackup --datadir=/var/lib/mysql --port=13306 --host=localhost --stream=xbstream --backup --target-dir=./ | /snap/bin/gsutil cp - “gs://clareity-bucket-dev/dev01\_backup.xbstream”

Did you verify the file contents? Did you test my file?
