the Firebird server, the memory usage is normal and nothing strange
happen. The Page cache size for the database is 4096 (The default
size). I think it is easy to replay in your desktop too. Just grab a
database of size about 800M to 1G, then try do GBAK in command prompt.
While the backup is in progress, open task manager and notice how the
physical RAM is consuming.
