# Backup utility "pg_dump" path setting

This setting controls where AyaNova will find the PostgreSQL pg_dump utility used for [automated backups](ops-form-backup.md).

## 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

```json
{
  ...other properties...
  "AYANOVA_BACKUP_PG_DUMP_PATH": "/usr/lib/postgresql/14.1/bin/"
}
```

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

```json
{
  ...other properties...
  "AYANOVA_BACKUP_PG_DUMP_PATH": "C:\\Program Files\\PostgreSQL\\14\\bin"
}
```

Example command line parameter

`ayanova.exe --AYANOVA_BACKUP_PG_DUMP_PATH="/usr/lib/postgresql/14.1/bin/"` (not real)

Example environment variable

Windows

`set "AYANOVA_BACKUP_PG_DUMP_PATH=C:\Program Files\PostgreSQL\14\bin"` (not real)

Linux / MAC

`export AYANOVA_BACKUP_PG_DUMP_PATH="/usr/lib/postgresql/14.1/bin/"` (not real)
