What are the best methods for backing up PostgreSQL databases?
There are several effective methods for backing up PostgreSQL databases, including SQL dump, file system-level backup, and continuous archiving.
Can you explain the SQL dump method?
Sure! The SQL dump method uses the pg_dump
utility to create a text file with SQL commands that can recreate the database.
What about the file system-level backup?
File system-level backup involves copying the database files directly from the file system while ensuring the database is in a consistent state.
How does continuous archiving work?
Continuous archiving allows you to back up the transaction logs continuously, enabling point-in-time recovery.
