SwitchFS (or SFS) is a lightweight file system layer designed to combine file systems located on multiple drives and/or multiple servers into a single logical file repository. SFS is built on top of FUSE (the "filesystem in userspace" layer).

New feature in r34:

• File level replication levels are (optionally) checked and reinforced during mount.

• Drive file storage load balancing across source drives. Add the "-balance" flag to initiate a directory integrity check and file rebalancing during mount.
• GCC 4.3 compatibility.

Features in the stable release:

• Sharable and expandable through NFS, SMB, etc.
• Data replication and automated backup across multiple physical drives specified at the directory level.
• Optimal space utilization given any combination of drives.
• Raw HD data and files still readable on other computers.
• Exported as 1 virtual drive.

Upcoming features:

• Maximized performance throughput across drives.
• Better support for power management.

Target users:

• People, like us, who have collected too many disk drives and computers over the years and want to make use of them.
• Small businesses which need reliable and transparent backup capabilities.
