Things aren't that simple. There is no 1:1 correspondence between files
and s3 objects. One file may be split among multiple S3 objects, and one
S3 object may hold contents for multiple files.
To figure out what parts of a file are stored in what objects, you need
to get the files inode from the contents table, the inode's block_ids
from the inode_blocks table, and then the object id that holds each
block from the blocks table.

This information is not stored in the database. However, after you
unmount (or run s3ql flushcache), everything that's in the database is
guaranteed to be stored in S3.
