VPOP3 version 3 and later will, by default, make a backup of the database used by VPOP3 into a file. This uses the PostgreSQL utility 'pg_dump'

If an error occurs whilst running this program, VPOP3 will create a 'Database Backup Failed' error message to the administrator.

The error message will look like:
The Database backup task failed with error code nnn
The command VPOP3 ran was ““c:\vpop3\pgsql\bin\pg_dump.exe” -F c -h localhost -p 5433 -U vpop3 -f “DBBack-2.dmp” vpop3”
The output of the program was:

The error code 'nnn' is the first place to look.

• '2' or '3' - check that the command (c:\vpop3\pgsql\bin\pg_dump.exe in the above example) exists on the VPOP3 computer. If PostgreSQL was installed into a different location, go to Settings → Database → Backup and change the path to the pg_dump.exe program.
