Backups and your data

Databases and app volumes live on persistent volumes that survive restarts, redeploys and new versions.

Keep your own backups

There is no backup and restore button for your data yet. Don’t rely on the platform alone: keep your own copies of anything you can’t lose.

Ways to keep a copy

• A nightly dump to object storage. A cron job linked to your database and a bucket: see the example in Cron jobs.
• A dump to your laptop with external access: pg_dump "$URL" > backup.sql.
• App files (uploads, SQLite): share the app’s data with a backup job: see Sharing an app’s data.
• Your setup as code: zc export -o zedcloud.yaml (secret values are left out).
• Your account data: Profile → Export my data.

What deleting does

You delete	What happens to the data
A database	Its volume is deleted. The dialog warns you.
An app with persistent storage	The volume is kept.
A Linux box	/workspace is kept.
Object storage	The key stops working at once; files are purged after 7 days.
A Valkey cache	It held data in memory only.
