Automated backup and disaster recovery system

About project:

Client overview

A leading data management company sought to optimize their database backup and restoration processes for large-scale tables that require complete refreshes. Their existing system involved periodic data dumps and manual restoration procedures, which were inefficient and susceptible to human error. The client needed an automated solution to streamline their data management operations and ensure data integrity.

Tech Stack:

Manual data dump and copy process, possibly using basic shell scripts and cron jobs.

Tech stack after migration:

Automated data dump and copy system using Python scripts, airflow jobs for scheduling, parallel restoration script using Python scripts.

Time to deliver project:

4-6 weeks

Problem

  • The client needed a reliable method to save and restore up-to-date data in large tables that are fully refreshed instead of gradually updated. Manual intervention was often required, which made the process time-consuming and prone to errors.

Inspection

  • While implementing a backup and restore tool, we faced challenges with several large tables that are always completely refreshed. Initially, these tables were dumped every 2 hours and stored on a separate server. However, restoring them required manual access to the server via SSH, followed by a sequential copy command for each table. To streamline this, we developed a script that automatically checks the list of tables needing restoration and performs the process in parallel. This automation significantly reduced restoration time and simplified management.

Recommendation

  • It's recommended to automate the backup and restoration processes as much as possible, minimizing human involvement to reduce the chance of errors. Parallel processing should be utilized to ensure that the most up-to-date data is available as quickly as possible.

Resolution

We implemented an automated system to dump and copy large tables to a separate server every 2 hours, coupled with a parallel restoration script. This reduced recovery time and minimized the need for manual intervention.
