What are some effective data recovery techniques for Rails applications?

There are several techniques you can use for data recovery in Rails applications, such as using database backups, leveraging ActiveRecord's built-in methods, and employing third-party recovery tools.

Can you explain how to use database backups for recovery?

Certainly! Regularly scheduled database backups can be restored to recover lost data. You can use tools like pg_dump for PostgreSQL or mysqldump for MySQL to create backups.

What if I don't have a backup? Are there other options?

If you don't have a backup, you might consider using ActiveRecord's find_by method to retrieve deleted records if they haven't been permanently removed, or check if your database supports point-in-time recovery.

Are there any third-party tools you recommend?

Yes, tools like Data Rescue, Stellar Data Recovery, and Recuva can help recover lost data from your database, but their effectiveness can vary.
