Question

i want to backup firebird database. Below is command that i use to execute the backup.

gbak -b -v -user SYSDBA -pass ***** -service localhost:service_mgr -verify -y E:/logs/backup_20111104.log D:\data\campaign.FDB E:/backup/campaign_20111104.fbk -FIX_FSS_METADATA WIN1252 -FIX_FSS_DATA WIN1252

However, after 2 hours running, it ends with general error(only in last line). Below is the error.

gbak:22068 records written
gbak:    writing data for table AA_1307265720107_842
gbak:19872 records written
gbak:    writing data for table AA_1301338383915_1025
gbak:4 records written
gbak:Exiting before completion due to errors

There is 700+ tables in this database. And the database size is 129GB.

I need to get complete stacktrace(if any). Or any idea where to check so i can know the actual error?

Answer 1

Try to repair the database before backup:

gfix -mend -full -ignore <db name> -user sysdba -pas masterkey

While backing up add two switches -g -ig in order to prohibit garbage collection and ignore check sum errors.
