Interesting that FB 3.0 reduces the nbackup time. Thanks for the info.
We have so many installations so I think we will wait for FB 4.0 which have
incremental nbackup restore and native replication.

Hi Hugo,
In HQbird, we monitor size and age of delta files.
If it is bigger or older than appropriate size/age (like 500Mb/6 hours,
for example), the database is marked as critical in Control Center.
You can implement the same - the status of the database and path to
delta file can be retrieved

Hi Hugo,
So if the computer is shutdown during a nbackup the database is locked
in this way indefinelty?
Yes, it's one of the most prevalent problems with nbackup.
To prevent it you need to monitor delta file age and size - manually, or
automatically using our FBDataGuard tool.

Hello,
If you have moved or deleted .delta-file, you got the correct message.
If delta file was corrupted, or database was corrupted in the way which
prevent merge, there could be various error messages.

Correct, but that information is actually stored as a "version number" in the
