Amazon S3 integration
for city backups and exports
Amazon S3 and S3-compatible storage such as MinIO and Wasabi hold backups, exports and archives for many city IT teams. A bucket the city controls is a simple, cheap place to keep plain copies of important data.

§ Overview
What connecting Amazon S3 does.
SentraBridge reads files from a bucket, writes new ones and archives processed files. Typical flows write nightly JSON or CSV backups of cloud systems into the city's own bucket. The backup lives in your storage; SentraBridge keeps only counts and file names.
- Files: Read CSV, JSON, JSON Lines, XML, fixed-width and GeoJSON files; write files by key.
- New files: Start or filter flows on files new since the last run under a prefix.
- Archive: Move processed files to an archive prefix.

§ Use cases
What cities connect Amazon S3 for.
A database table as CSV
A permits table is exported nightly to a dated CSV, so there's always a plain-text copy outside the database.
Files for a data warehouse
Records from several systems are written as JSON Lines under one prefix for the analytics team.
On-premises MinIO
Self-hosted cities write exports to their own MinIO server with the same S3 settings.
