# without providing path to the database file
# backup will be stored in the user home directory
# with name salt_portal_yyyymmdd_hhmmss.db where yyyymmdd_hhmmss
# is the current date and time
run_backup(username='myusername', password='mypassword')

# provide location for the backup adding database_path keyword
# example below will create the my_backup.db database in the current
# working directory of the python session
run_backup(username='myusername', password='mypassword', 
           database_path='my_backup.db')
```

### Usage as CLI

Backup to C:\Users\myusername\salt_portal_20240826_135932.db
 projects:  33%|████████████████████████▎                                                | 3/9 [01:25<02:31, 25.22s/it]
 station in project:  12%|███████▉                                                       | 1/8 [00:01<00:11,  1.66s/it]

```

## Limitations

- Rating curves are currently not stored in the backup database
- Information on upstream probes is partially missing (i.e. not marked as upstream probe, group often missing, 
no info on probe used in which calculations)

## Building the pyinstaller exe

```console
pyinstaller src/salt_portal_backup/backup.py --onefile --name salt_portal_backup --icon static/icon-256.ico
```
