HAMMER is a high-availability 64-bit redundant clustering file system developed by Matthew Dillon for DragonFly BSD using B-trees. Its features include infinite snapshots, multi-master operation, configurable history retention and self-healing. There is a stalled effort to port HAMMER to Linux. Requires a pruning/reblocking cron job run a few minutes every night to incrementally clean up and regain space on the filesystem. Does not yet support multi-master configuration.
