If all applications exclusively use the "dir/" naming scheme and the bucket does not contain any objects with a different naming scheme, this option can be used to disable support for alternative naming schemes. When FUSE release() is called, s3fs will re-upload the file to s3 if it has been changed, using md5 checksums to minimize transfers from S3. If the cache is enabled, you can check the integrity of the cache file and the cache file's stats info file. Well also show you how some NetApp cloud solutions can make it possible to have Amazon S3 mount as a file system while cutting down your overall storage costs on AWS.

In mount mode, s3fs will mount an amazon s3 bucket (that has been properly formatted) as a local file system. Enable no object cache ("-o enable_noobj_cache"). Possible values: standard, standard_ia, onezone_ia, reduced_redundancy, intelligent_tiering, glacier, and deep_archive. The first line in file is used as Customer-Provided Encryption Keys for uploading and changing headers etc. 600 ensures that only the root will be able to read and write to the file.
