# Backup utility "pg_dump" path setting

This setting controls where AyaNova will find the PostgreSQL pg_dump utility used for automated backups.

## Default

Default varies with installer platform but empty is valid if pg_dump utility is in the PATH.

If no override is specified AyaNova will assume the utility is on the environment PATH.

## Overriding

AyaNova expects the pg_dump utility path to be provided by a config.json property, environment variable or command line parameter named

`AYANOVA_BACKUP_PG_DUMP_PATH`

The value specified should be a string containing a fully qualified file path to the pg_dump utility.

Example LINUX config.json entry

    {
      ...other properties...
      "AYANOVA_BACKUP_PG_DUMP_PATH": "/usr/lib/postgresql/16.3/bin/"
    }

Example WINDOWS config.json entry (Back slashes need to be doubled in config.json file or the server will fail to start)

    {
      ...other properties...
      "AYANOVA_BACKUP_PG_DUMP_PATH": "C:\\Program Files\\PostgreSQL\\16\\bin"
    }

Example command line parameter

`ayanova.exe --AYANOVA_BACKUP_PG_DUMP_PATH="/usr/lib/postgresql/16.3/bin/"` (not real)

Example environment variable

Windows

`set "AYANOVA_BACKUP_PG_DUMP_PATH=C:\Program Files\PostgreSQL\16\bin"` (not real)

Linux

`export AYANOVA_BACKUP_PG_DUMP_PATH="/usr/lib/postgresql/16.3/bin/"` (not real)
