Tahoe-LAFS

Tahoe-LAFS is a free and open, secure, decentralized, fault-tolerant, distributed data store and distributed file system. It can be used as an online backup system, or to serve as a file or Web host similar to Freenet, depending on the front-end used to insert and access files in the Tahoe system. Tahoe can also be used in a RAID-like manner to use multiple disks to make a single large reliable/redundant array of independent/inexpensive nodes (RAIN) pool of data storage. see more

environment

Environment

?

A storage solution can be deployed over an environment which is or not completely controlled by a single entity e.g a company.

controlled uncontrolled
scalability

Scalability

?

The ability to scale out heteroegeneously allows for more diverse storage deployments.

homogeneous heterogeneous
redundancy

Redundancy

?

Different redundancy mechanisms can be provided, each with its tradeoffs.

erasure codes replication
fault-tolerance

Fault Tolerance

?

The ability to maintain a storage system operational requires being able to cope with "unexpected" behaviors.

security

Security

?

A secure storage system must be designed with encrypted communications, access control etc. from the ground up.
