A storage approach that organizes data as files in directories with hierarchical filesystem semantics, typically accessed via NFS or SMB.
DESCRIPTION
File storage presents a hierarchical namespace of files and directories, enforcing file-level permissions and supporting shared access by multiple clients. It is common for legacy applications, analytics workloads reading flat files, and collaborative environments. Protocols like NFS and SMB provide network access to file shares on-premises or in cloud services such as EFS, Azure Files, and Filestore. Compared to object storage, file storage offers stronger POSIX semantics and path-based organization; compared to block storage, it removes the need to manage raw volumes.
ALTERNATIVE DEFINITIONS
Amazon Web Services
Amazon EFS provides a simple, serverless, set-and-forget elastic file system for Linux-based workloads.

TOP QUESTIONS
When should I choose File Storage over Object Storage?
Choose File Storage for POSIX semantics, shared filesystem mounts, and applications expecting path-based access. Object Storage suits scalable, immutable blobs and HTTP API access.
Category: Comparison
What protocols are commonly used with File Storage?
NFS and SMB are the most common network file protocols. They provide shared access, permissions, and directory semantics to multiple clients.
Category: Basics
How does File Storage scale in the cloud?
Managed services like EFS, Azure Files, and Filestore provide elastic capacity and performance tiers, with regional redundancy options for resilience.
Category: Scalability
What are risks of using File Storage for analytics?
Potential bottlenecks under high concurrency, and limited throughput compared to object storage. Misconfigured permissions can cause access errors.
Category: Risks
How is security managed in File Storage?
Use IAM and ACLs, network isolation, encryption at rest and in transit, and regular audits of access control lists and shares.
Category: Security
What performance settings matter for File Storage?
Throughput modes, client mount options, read/write concurrency, and caching behavior are key. Tune for workload patterns.
Category: Performance
What is a typical use case for File Storage?
Shared datasets for ML experiments, home directories, content management systems, and legacy applications needing filesystem semantics.
Category: UseCase
How do backups work for File Storage?
Use snapshots and scheduled backups via cloud services or NAS tools, with tested restore procedures to meet RPO/RTO.
Category: Operations
How does File Storage fit into data lakes?
File storage can host raw and curated files, though object storage is often preferred for cost and scalability. Some lake engines read from both.
