A curated list of storage open source tools. Backups, redundancy, sharing, distribution, encryption, etc.
Systems that expose a traditional file system interface with POSIX semantics.
-
Ceph file system - Ceph’s file system runs on top of the same object storage system that provides object storage and block device interfaces. The Ceph metadata server cluster provides a service that maps the directories and file names of the file system to objects stored within RADOS clusters. The metadata server cluster can expand or contract, and it can rebalance the file system dynamically to distribute data evenly among cluster hosts. This ensures high performance and prevents heavy loads on specific hosts within the cluster.
-
LeoFS - LeoFS is a highly available, distributed, eventually consistent object/blob store. If you are searching a storage system that is able to store huge amount and various kind of raw data in its native format, LeoFS is suitable for that.
-
XtreemFS - XtreemFS is a general purpose storage system and covers most storage needs in a single deployment. It is open-source, requires no special hardware or kernel modules, and can be mounted on Linux, Windows and OS X.
