Hello,
I just started to see how to use replication with FirebirdSQL.
As far as I understand from my readings so far, async replication works on file systems.
The replica server must have access to the journal archive directory on the master server at file system level.
There is no option to make things work only over TCP/IP.
Is that correct?
Thanks & Regards,
Ertan

It is incorrect.
Replica side must receive journal files somehow. The "how" part is up to you.
You can use any transport based on TCP/IP, UDP or a courier with a flash drive.
You also should take care that the target Firebird server don't see
incomplete (in progress) files. It does the best to handle such situations but
not perfectly, so better to avoid them by copying files for temporary names and
then atomic rename.
