What are the best strategies for backing up and recovering PostgreSQL databases?
An example of an AI chatbot conversation about PostgreSQL backup and recovery strategies.
What are the best strategies for backing up and recovering PostgreSQL databases?
The best strategies include using pg_dump for logical backups, and pg_basebackup for physical backups. It's also important to implement WAL archiving for point-in-time recovery.
How often should I perform backups?
It depends on your data change rate, but a common practice is to perform daily backups and more frequent incremental backups if needed.
What is WAL archiving and why is it important?
WAL archiving allows you to save Write-Ahead Logging files, which are crucial for point-in-time recovery, ensuring no data loss.
Can you explain the difference between logical and physical backups?
Logical backups capture the database structure and data, while physical backups copy the actual database files. Logical backups are more flexible for migrations.
