Subject Re: [firebird-support] nbackup
Hi Alexey,

In my case the database is seldom larger 500 MB and the backup takes 30 maximum seconds.

Would it not be sufficient to check the  MON$BACKUP_STATE field (thanks Thomas) and if its stuck on state 1 or 2 for several minutes then I execute "ALTER DATABASE END BACKUP".
How do you recover if it's stuck?

I noticed that the larger the database is the longer it takes to do nbackup even if the delta is very small.
