First create a new project and a new storage bucket

Configure the google tool to work with the nearline storage

gsutil config  

Create a index file with each file you want to upload

find /Volumes/DATA/Events -type f -print0 | xargs -0 md5 > index_7_2_2016  

Create a 7z file with all files to upload

7z a -t7z -m0=lzma -mx=9 -mfb=64 -md=32m -ms=on backup_7_2_2016.7z /Volumes/DATA/Events/  

Use gsutil ls to see which is your bucket name

 gsutil cp index_7_2_2016 gs://bucketid/index_7_2_2016
 gsutil cp index_7_2_2016 gs://bucketid/backup_7_2_2016.7z
