MASSIVELY PARALLEL POSTGRES BACKUPS

Summary from the TLDR Dev newsletter

Massively parallel backups for sharded Postgres databases are designed to create consistent, encrypted snapshots every 12 hours with minimal impact on production queries. By using cloud infrastructure and advanced techniques like Write-Ahead Log (WAL) replay, these backups can efficiently handle petabyte-scale databases, reducing the time needed for backup processes through parallelism across multiple shards.
