We are backing up our databases regularly using gbak, running it on the 
same linux host as the Firebird server (2.5).

I've just noticed that we are referring to the database file using the 
local path alone, rather than using localhost:/pathname. I see that gbak 
is indeed reading the file directly rather than accessing it through the 
server (confirmed with strace).

The Firebird server may well have these databases open at the same time. 
This doesn't seem to be affecting things, and indeed the gbak seems to 
run quicker than when I run it via the server.

What's the impact of doing this? What's the preferred way? It's more 
important to minimise the impact of the backup job on the system load 
than it is to finish the backup quickly.



thanks,

Hamish
