But I take it then, that gfix -f -full does detect ALL kinds of errors in the physical database structure? A gbak backup + restore cycle should find logical errors, I assume. But a restore with the -inactive switch wouldn't find any violations of constraints that are based on underlying indices, right? I.e. it wouldn't detect duplicates in unique constraints or primary key violations? Regards, Kjell [Non-text portions of this message have been removed]

Or are there > corruptions that cannot be detected Gfix finds only errors in the physical structure of the database. These include problems like doubly allocated or unallocated pages, bad back version pointers, and orphaned back version chains. Gfix will not find logical data errors like duplicates in a unique constraint or broken foreign key relationships. Cheers, Ann >
[firebird-support] gfix -v -full sufficient?
Hi, Does gfix -v -full detect all kinds of database corruption? Or are there corruptions that cannot be detected that way? I haven't seen any indications of anything wrong, I'm just trying to check as best I can after a migration. I have already tested a full gbak backup successfully, and will also try a restore from that backup. Mvh, Kjell [Non-text portions of this message have been removed]
