Duplicati is a free and open source backup client for securely storing your data. Duplicati stores encrypted, incremental, compressed backups on cloud storage services and remote file servers using AES-256 encryption, keeping your data safe and always updated. It works with most storage services, including Google Cloud and Drive, Amazon S3, Microsoft Azure and OneDrive, Dropbox, FTPOpenStack Storage (Swift), SSH (SFTP), WebDAV, Tencent Cloud Object Storage (COS), and more! Duplicati also works on all major platforms (Windows, Linux and OSX). Unlike many other backup solutions, Duplicati ensures that your data is stored securely far away and updated regularly. Incremental updates means it saves on bandwidth and storage space, with a scheduler that automatically keeps your backups up to date.

Dbmate is a database migration tool, to keep your database schema in sync across multiple developers and your production servers. It is a standalone command line tool, which can be used with Go, Node.js, Python, Ruby, PHP, or any other language or framework you are using to write database-backed applications. This is especially helpful if you are writing many services in different languages, and want to maintain some sanity with consistent development tools. Supports MySQL, PostgreSQL, SQLite, and ClickHouse. Uses plain SQL for writing schema migrations. Migrations are timestamp-versioned, to avoid version number conflicts with multiple developers. Migrations are run atomically inside a transaction. Supports creating and dropping databases (handy in development/test). Supports saving a schema.sql file to easily diff schema changes in git. Database connection URL is defined using an environment variable (DATABASE_URL by default), or specified on the command line.

jdbc2csv is a small command-line tool written in JAVA and can be used on all platforms, for which JRE 8 or higher is available. To connect to a specific DBMS the tool uses its JDBC driver. The result of the executed 'select' query is displayed in CSV format ( different standards are supported ). When there is an error the tool stops with exit code 1 and the error message is output on stderr. jdbc2csv is created with a main purpose to be used in shell-scripts. Relatively easy to configurate, this tool is suitable for queries ‘select’, ‘update’ and ‘delete’. I think that is not suitable for a large number of requests, like 'insert'.

Apple has a utility in /usr/bin named tccutil, but it only supports one command, which is to reset the entire database. It has been like this for many versions of macOS. I wanted a command-line utility that would be able to add, remove, list, and take other actions. This tool needs SIP disabled in order to function. The risk of doing so is up to you. tccutil.py can be installed without any additional software. Depending how you have your $PATH variable setup, you can simply type tccutil (instead of the full path) and it will run this utility instead of Apple's. This utility needs super-user priveleges for most operations. It is important that you either run this as root or use sudo, otherwise it won't work and you will end up with “permission denied” errors.
