Hi,

 

I have a problem and my ideas to solve it are getting to an end. Hopefully you can help me.

 

When I try to make a backup with nbackup on our customer’s system (Windows Server 2016 – Firebird 3.0.3) we get the following message, while we are connected to the database with the “IBExpert” at the same time. When we are not connected, the backup will run.

 

d:\SYSTEM\Firebird_WORK\nbackup.exe -U SYSDBA -P mypassword -B 0 D:\DATENBANK\SHS.FDB D:\DATENBANK\SHS_Backup_Work_0_Test.nbk

[

PROBLEM ON "attach database".

I/O error during "CreateFile (open)" operation for file "D:\COMED\DATENBANK\SHS.FDB"

-Error while trying to open file

-The process cannot access the file because it is being used by another process.

SQLCODE:-902

]

 

When I try it on my local machine there is no problem even when I access the database with the IBExpert and make a nbackup at the same time. I double checked the settings in the IBExpert and they seem to be identical. I am not sure what the cause of the problem is: Firebird, IBExpert, some settings (Firebird, IBExpert), perhaps the Anti-Virus software…

The Firebird Log does not give any hints.

 

Does anyone have an idea what I can do or what I can check to solve this issue.

 

Best regards

Nils Andernach
