Buckets can be configured to have `Hard` quota - it disallows writes to the bucket after configured quota limit is reached.

## Prerequisites

- Install MinIO - [MinIO Quickstart Guide](https://min.io/docs/minio/linux/index.html#procedure).
- [Use `mc` with MinIO Server](https://min.io/docs/minio/linux/reference/minio-mc.html#quickstart)

## Set bucket quota configuration

When an object is deleted from the source bucket, the corresponding replica version will be marked deleted if delete marker replication is enabled in the replication configuration. Replication of deletes that specify a version id (a.k.a hard deletes) can be enabled by setting the `DeleteReplication` status to enabled in the replication configuration. This is a MinIO specific extension that can be enabled using the `mc replicate add` or `mc replicate edit` command with the --replicate "delete"...

Bit Rot, also known as data rot or silent data corruption is a data loss issue faced by disk drives today. Data on the drive may silently get corrupted without signaling an error has occurred, making bit rot more dangerous than a permanent hard drive failure.

MinIO's erasure coded backend uses high speed [HighwayHash](https://github.com/minio/highwayhash) checksums to protect against Bit Rot.
