i'm actually managing a project on GCP where there is an application made up of 2 virtual instances. One of this VM has a "data" hard disk ( logical volume of 5 tb made of 5 HD ) that is constantly used by the application: kinda CRM with a lots of data.
Using the Cloud Storage Bucket seems to be one possible way to achieve the "daily backup" but i was wondering if "rsyncing" 5tb ( and more every day ) into the bucket is the best way to go. considering that Google does not recommend use "gcloud storage rsync" command for more than 1tb, the time to complete the task seems to be X3 of a normal rsync Actually i've read also about "Filestore" service but seems to be too expensive for our budget. Considering also the costs, i was wondering if is it better to create directly another VM with a 5tb clone? There are other possible ways ?
Thanks a lot for the support!
