Subject Unable to backup production database with gbak and SuperServer 3
Author Köditz, Martin



I’m trying to backup my production db using gbak.

I’m running command:

Gbak –v prod.fdb prod.fbk


As result:

gbak: ERROR:I/O error during "lock" operation for file "prod.fdb"

gbak: ERROR:    Database already opened with engine instance, incompatible with current

gbak:Exiting before completion due to errors


I’m using Firebird 3 ( on OpenSuse 13.2 x64

gbak:gbak version LI-V3.0.0.32483 Firebird 3.0


Is there a restriction with backup on SuperServer?
