This doesn't look to work correctly:

$ journalctl -b | head
-- Logs begin at Thu 2017-04-13 14:05:51 CEST, end at Thu 2019-08-01
08:51:39 CEST. --

revision 0x25, date = 2018-04-02

$ journalctl -o export -b | /usr/lib/systemd/systemd-journal-remote -o
/tmp/foo.journal -
$ journalctl -b --file=/tmp/foo.journal | head
-- Logs begin at Sat 2019-06-22 18:32:31 CEST, end at Thu 2019-08-01

path /org/freedesktop/PolicyKit1/AuthenticationAgent, locale
en_US.UTF-8) (disconnected from bus)

As you can see, the start is not the same.

Also are foo.journal data compressed ?

Thank you.
