FUSE-based file system backed by Amazon S3
s3fs is a FUSE filesystem that allows you to mount an Amazon S3 bucket as a local filesystem. It stores files natively and transparently in S3 (i.e., you can use other programs to access the same files). Maximum file size=64GB (limited by s3fs, not Amazon).
s3fs is stable and is being used in number of production environments, e.g., rsync backup to s3.
Important Note: Your kernel must support FUSE, kernels earlier than 2.6.18-164 may not have FUSE support (see issue #140 ). Virtual Private Servers (VPS) may not have FUSE support compiled into their kernels.
