Amazon EFS is easy to set up: you can use the AWS management console, API, or command-line. Amazon EFS can grow to petabytes and deliver consistent low latencies and high levels of throughput. This solution can scale up or down as needed (as files are added or removed). It is pay-per-use - you will only pay for the storage you are using. This eliminates storage administration tasks and is a real time-saver. There is no minimum fee and no setup cost.
You do need to have some programming knowledge to use Amazon EFS. You need to closely monitor the time constraints in relation to the amount of data you are backing up with or your process may fail. You most likely need to manually pause applications and processes backing up, and only backups can be stored on Amazon EFS.
With Azure File Storage you can easily share data across cloud and on-premises servers. Azure File Storage can help simplify hosting for high availability workload data and migrate file share-based applications to the cloud, with no code changes. You can access what you need anytime, anywhere, using any device.
Setup and deployment with Azure File Storage can be quite complex. We believe this solution should support more legacy storage systems and have better overall integration with other solutions. Azure File Storage has some scalability limitations, which could be problematic for some. The pricing should be more transparent so that you have a better idea of what your incurred costs will be.
Using either of these solutions, one does need to be a bit tech-savvy. They are not for the complete novice.
We like Amazon EFS best. The easy and flexible scale up and down protocol that it has in place is perfect for our ever-changing business organizational needs. For us, Amazon EFS is very cost-effective and time-efficient. We like that.
