The only thing is, tar.bz2 archives are compressed after the tar archive is
complete. This allows for redundancy between files to be used, but isn't
good for backup purposes.
You might be able to recover some of the archive, but it might be
considerably less than 2GB. For backups, I suggest using uncompressed tar,
or a utility such as dar, which compresses before archiving  (zip does
that, but can't handle large archives).

In any case, the moral is to test such backups before wiping your original
home directory!
