A practical guide to PostgreSQL backup strategies comparing managed services (AWS RDS, Google Cloud SQL, Aiven) and open-source tools. Covers RPO/RTO, PITR, and how to choose based on database size, infrastructure, and team expertise.
if you run postgresql in production, your backup strategy is your safety net. recovery point objective (rpo) and recovery time objective (rto) aren't just acronyms — they're the difference between a five-minute hiccup and a lost weekend. the good news: you have solid options, whether you want to offload backups entirely to a managed service or keep full control with battle-tested open-source tools.1
managed postgresql services handle backups automatically, including point-in-time recovery (pitr), so your team can focus on building features instead of cron jobs.
amazon's managed postgresql service is the industry standard for a reason. it gives you automated backups with a retention period of up to 35 days, manual snapshots that persist beyond that, and multi-az deployment for high availability. pitr lets you restore to any second within the retention window. if you're already on aws, this is the path of least resistance.
google cloud sql offers automated backups with configurable schedules, pitr using write-ahead log (wal) archives, and cross-region replication for disaster recovery. it integrates deeply with the google cloud ecosystem — think iam for access control and cloud monitoring for backup health alerts. a strong choice if gcp is your home.
aiven is the cloud-agnostic option. it runs on aws, gcp, azure, and digitalocean, so you're not locked into a single provider. automated daily backups, pitr, and a 99.99% uptime sla on some plans. aiven's backup management is straightforward — you can trigger on-demand backups and restore to a new service in a few clicks.
if you need more flexibility, lower cost at scale, or you're running self-hosted postgresql, these tools are worth your attention.1
pgbackrest is widely considered the go-to for production postgresql backups at scale. it supports full, incremental, and differential backups, parallel compression, and encryption. it handles terabyte-scale databases efficiently and integrates with s3, azure blob storage, and local filesystems. if your database is pushing into the tb range, start here.1
barman (backup and recovery manager) by enterpriseDB is built for centralized management of multiple postgresql instances. it supports remote backups, retention policies, and pitr. it's a solid pick if you have a dedicated dba team managing many databases from one control point.1
wal-g is the lightweight, cloud-native option. it archives wal files to s3, gcs, or azure storage and supports incremental backups. it's popular in kubernetes environments and pairs well with tools like patroni for high-availability setups.1
| scenario | recommended approach |
|---|---|
| small database (< 100 gb), want simplicity | managed service (rds, cloud sql, aiven) |
| large database (tb+), need performance | pgbackrest |
| multi-cloud or hybrid infrastructure | aiven or wal-g |
| centralized dba team managing many dbs | barman |
| kubernetes-native deployment | wal-g + patroni |
there's no single best backup tool — the right choice depends on your scale, infrastructure, and team. managed services (aws rds, google cloud sql, aiven) are excellent if you value automation and don't want to think about backup scripts. for self-hosted setups or large-scale deployments, pgbackrest is the industry standard, while barman and wal-g fill specific niches well.1
