Error with xbstream

MySQL & MariaDB Percona XtraBackup
1

I downloaded by xbstream file from gcp bucket
I used the following

but it gave me error

root@resuc1gdmyclb37:/mysql-data/db# xbstream -xv -C /mysql-data/db < /mysql-data/db/dev01_backup.xbstream
xb_stream_read_chunk(): wrong chunk magic at offset 0x0.
exit code: 1

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?
