some filesystems do not allow you to have files bigger then 2G :-( I do not
think that one file (even gzipped tar file) is good.

No problem, you can use one index file and hashes in it so files are then
stored as:
AA/AA/AA/00 AA/AA/AA/01
See how squid (http://www.squid-proxy.org/) does his job here. No problem,
I think. I really prefer this solution over one big file. You can easily
swap files with other databases, you can even create md5sum of md5sums of
each file so you can have a multi-md5sum of your database (you can be
really sure that your backup is OK, etc. :-).

No one (I hope) is arguing about the need for backing BLOBs from the DB :-)
