Then you can annex files and copy them to the remote as usual:

Note the use of the SHA1E [[backend|backends]]. It makes most sense
to use the WORM or SHA1E backend for files that will be stored in
the Internet Archive, since the key name will be exposed as the filename
there, and since the Archive does special processing of files based on
their extension.
Note that it probably makes the most sense to use the WORM backend
for files, since that exposes the original filename in the key stored
in the Archive, which allows its special processing for sound files,
movies, etc to be done.
Also, the Internet Archive has restrictions on what is allowed in a
filename; particularly no spaces are allowed.

There seems to be a bug in either hS3 or the archive that breaks
authentication when the bucket name contains spaces or upper-case letters..
