How to inspect nbak state of a Firebird database

Question

Is there a way in C# to inspect the nbak state of a Firebird database?

The state in the database header would be set to nbak_state_diff or nbak_state_normal. But how do I actually read this value?

Answer 1

Select MON$BACKUP_STATE From MON$DATABASE

Current physical backup (nBackup) state:
0 - normal
1 - stalled
2 - merge

Also see c:\Program Files\Firebird\Firebird_3_0\doc\README.monitoring_tables.txt

P.S. for C#-related questions it is often faster to ask in a dedicated Google forum, see http://stackoverflow.com/tags/firebird-.net-provider/info
