s3backer is a filesystem that contains a single file backed by the
|
|
Amazon Simple Storage Service (Amazon S3). As a filesystem, it is
|
|
very simple: it provides a single normal file having a fixed size.
|
|
Underneath, the file is divided up into blocks, and the content of
|
|
each block is stored in a unique Amazon S3 object. In other words,
|
|
what s3backer provides is really more like an S3-backed virtual
|
|
hard disk device, rather than a filesystem.
|
|
|
|
In typical usage, a normal filesystem is mounted on top of the file
|
|
exported by the s3backer filesystem using a loopback mount (or disk
|
|
image mount on Mac OS X).
|
|
|
|
By not attempting to implement a complete filesystem, which is a
|
|
complex undertaking and difficult to get right, s3backer can stay
|
|
very lightweight and simple. Only three HTTP operations are used:
|
|
GET, PUT, and DELETE. All of the experience and knowledge about
|
|
how to properly implement filesystems that already exists can be
|
|
reused.
|
|
|
|
By utilizing existing filesystems atop s3backer, you get full UNIX
|
|
filesystem semantics. Subtle bugs or missing functionality relating
|
|
to hard links, extended attributes, POSIX locking, etc. are avoided.
