Sorry, I just realised I was thinking of an option that had been removed. You 
need to run Firebird as SuperClassic or Classic (or do the backup through 
localhost as suggested earlier.

You need to backup through localhost, or you need to set the database in 
databases.conf (or the Firebird default in Firebird.conf) to Shared.
You should have had the same problem with Firebird 2.5 if you used SuperServer.

Hello,
i am currently testing to migrate FB2.5 databases into FB3 databases. Cant tell 
how many hours i recoded SP, triggers and and and... but database is working 
for me now.

Then i came to the point to backup the FB3 databases on a running system. Yes, 
i read the manuals and release notes and searched google. Unfortunately that 
didnt help. People refer to release notes and quick start quide or telling that 
something has changed for security reasons. Fact is database file is locked if 
any user is connected nowadays so i cant do my backups as before. I can 
understand that new feature. Company i work for is a 24/7 business. So i have 
to plan backups on a running system. I cant tell them to stop working for even 
1.5 hours because backup is running.
In the past i used nbackup but i had issues with deadlocks and missing 
transactions. So i used gbak fo
r last two years. Worked perfect for me. I tried different commands, settings 
and configurations for example service manager, IP, localhost, ports, password, 
transportable thrusted auth, SharedDatabase, adding users, dbadmi, new virtual 
machines and other Windows OS. Nothing worked for me as long as one user stays 
connected.
I also tried using a gbak 2.5 version with a FB3 database. That backup started 
after i tried to use default sysdba password even if i changed password before.
Operating system is Windows Server 2012 R2. Firebird 3.0.0.32483 SuperServer. 
Backup routine, database file and backup file should be located on the same 
machine for the moment.

"C:\Program Files\Firebird\Firebird_3_0\gbak.exe" -b -v -t -se service_mgr 
employee e:\xxx.bak -user SYSDBA
works if no one is connected else i always get error "file is used 
by another process".

Hopefully i will find some answers, suggestions or advices.


Regards and thanks
Thomas
