Installation

Instructions to install the CLI on different operating systems.

Install via Cargo

cargo install r-backups

Install from Source Code

1. Clone this repository:

git clone https://github.com/HormigaDev/r-backups.git
cd r-backups

2. Build and run:

cargo build --release

Usage

Basic explanation of how to use the CLI.

r-backups [options] [arguments]

<> means required and [] means optional

Configuration

For the CLI to work correctly, you must have the following environment variables configured in a .r-backups file in the directory where you will use the CLI or in the system's environment variables.

DATABASE_HOST=<host>
DATABASE_USER=<user>
DATABASE_PASSWORD=<password>
DATABASE_NAME=<database name>
DATABASE_PORT=<port>
BACKUPS_DIR=path/to/backups_directory/
MIGRATIONS_DIR=path/to/migrations_directory/
CHANGELOG_FILE_PATH=path/to/chagelog

Initial configuration to use the CLI correctly

r-backups init

Note:

The changelog file conventionally has no extension, and its content must initially be an empty array or an array of objects in the following format:

[
    {
        "id": "migration_id",
        "group": "database_prefix e.g., (company_)"
    }
]

Commands

backup

This command creates a backup of a specific database.

Usage:

r-backups backup --database <database_name>

For this command to work correctly, the backups configuration must be set.
See Configuration.

restore

This command restores a backup from a specified file.

Usage:

r-backups restore --database <database_name> --file path/to/backup_file.backup.sql

migration

This command is used to apply or revert a specific migration for a group of databases.
You can also use this command to generate a new migration.

Usage:

Generating a new migration:

r-backups migration --generate --group <group_name> --name <migration_name>

When generating a migration, the CLI uses a unique identifier for each migration, consisting of a 5-digit numeric prefix.
For example, the CLI could generate a migration named 00001_create_table_users.sql.

The migration body contains the following:

-- up
your SQL code here;

-- down
your rollback SQL code here;

It is IMPORTANT not to delete the -- up or -- down comments so the CLI can identify them correctly.

Updating a group of databases:

r-backups migration --up --id <migration_id> --group <group_name>

Reverting a specific migration:

r-backups migration --down --id <migration_id> --group <group_name>

Note:
For this command to work correctly, the changelog and migrations configurations must be set.
See Configuration.

update

This command applies all pending migrations to a group of databases or a specific database.
It can also rollback the last migration for a group of databases or a specific database.

Usage:

Updating a group of databases:

r-backups update --apply --group <group_name>

Updating a specific database:

r-backups update --apply --database <database_name>

Rolling back the last migration for a group of databases:

r-backups update --rollback --group <group_name>

Rolling back the last migration for a specific database:

r-backups update --rollback --database <database_name>

createdb

This command creates a database with a specified name.

Usage:

r-backups createdb --name <database_name> --sql [path/to/file.sql]

drop

This command drops a database and requires confirmation before deletion.

Usage:

r-backups drop --database <database_name>

list

This command lists all existing databases.

Usage:

r-backups list

count

This command returns the number of databases present, including templates.

Usage:

r-backups count

rename

This command renames a database to a specified new name.

Usage:

r-backups rename --database <old_name> --to <new_name>

Options

Examples
