# PgBackRest backup wrapper

Wrapper to call the full/differential backup on all stanzas

## Options

```txt
-b (backuptype): full/diff
-s (stanza): override stanza name, must be in stanza.cfg file
-l list available stanza
-t test run
```

Either `-l` or `-b` option must be set

## Config

Two files must be created

### `config/pgbackrest.cfg`

Example file is `pgbackrest.sample.cfg`

This file holds the sudo_user for calling the commands and the main pgbackrest config file.
If the super user or config file does not exists an error will be shown

```ini
[PgBackRest]
sudo_user=postgres
pgbackrest_config=/etc/pgbackrest.conf
```

### `config/stanza.cfg`

Example file is `stanza.sample.cfg`

This files holds the stanzas to backup

`stanza:repo number:path to config file:super user`

If the stanza has several repo settings as in "repo1-...", "repo2-..." then the repo to target can be listed in here by ":repo number"

The third optional parameter is a config file path

The forth optional parameter is the super user to use

If parameters are not used but laters are, the empties need to be set with just the ":"

`stanza::/config`

The script checks for the following things during each run

- stanza name exists in the main config file, or in the override config file if set
- check if repo number exist in main config file, or in the override config file if set
- override config file exists
- override super does not exist

```ini
[stanzas]
stanza_a
stanza_b:1
stanza_b:2
stanza_c::/etc/to/config
stanza_d:::super user
```
