You use git-hash-object to put file (-t blob) into the object database.
It would return sha1 of added object. Use git-tag to create tag to blob
(use returned sha1 for head). You can get file (to stdout) with 
"git cat-file blob tagname^{blob}".

The file would be in object database, but not in working directory
by default.

Can't you store them uncompressed?
