Database Backups

QuickStack runs isolated backup containers that connect to your managed database and produce compressed dump files, then upload them to S3.

Prerequisites

• At least one S3 target configured
• A managed database running in your project

Configure a database backup schedule

1. Open your database app.
2. Go to the Storage tab and click Add Backup Schedule.
3. Configure:

Field	Description	Example
Cron Expression	When to run	0 2 * * * (daily at 2 AM)
Retention	Number of dumps to keep; oldest deleted when exceeded	7
Backup Location	Which S3 target to use	select from list

4. Click Save.

Dump formats

Engine	Tool used	Format
MariaDB	mariadb-dump	.tar.gz
PostgreSQL	pg_dump	.tar.gz
MongoDB	mongodump	.tar.gz

Troubleshooting

Problem	Fix
Backup fails	Check that the database is running; inspect backup pod logs in the Backups page
Upload fails	Confirm S3 credentials and bucket permissions
Dump is empty or corrupted	Verify database credentials are correct; check for database errors
