mc — The MinIO client: work with any S3-compatible object storage (MinIO, AWS S3, Azure via gateway, Ceph) — buckets, copies, mirrors, policies.

ماذا يفعل

MinIO is a fast S3-compatible object store you can run yourself (on VMs or Kubernetes) — useful for backups, Loki/Tempo storage, Terraform state in labs, and artifacts. mc works with aliases (a URL + keys) and has Unix-like commands: ls, cp, mirror, rm, cat, plus admin commands for users and policies. On some systems the binary is called mcli to avoid a clash with Midnight Commander.

$ مستخدم عادي# بصلاحية root (أو مع sudo)

1Run MinIO for a lab

$podman run -d --name minio -p 127.0.0.1:9000:9000 -p 127.0.0.1:9001:9001 -e MINIO_ROOT_USER=admin -e MINIO_ROOT_PASSWORD=labonly-2026 quay.io/minio/minio server /data --console-address :9001

2Set an alias and make a bucket

$mc alias set lab http://127.0.0.1:9000 admin labonly-2026
$mc mb lab/backups
$mc ls lab

3Copy and list files

$mc cp backup-2026-10-27.tar.gz.age lab/backups/web1/
$mc ls --recursive lab/backups/

4Mirror a folder every night (backup)

$mc mirror --overwrite /srv/backups lab/backups/web1

5Turn on versioning and default encryption

$mc version enable lab/backups
$mc encrypt set sse-s3 lab/backups

6Delete backups older than 30 days with a lifecycle rule
```
$mc ilm rule add --expire-days 30 lab/backups
```

7Make sure nothing is public

$mc anonymous get lab/backups
$mc anonymous set none lab/backups

8A user that can only write backups

$cat backup-writer.json
{"Version":"2012-10-17","Statement":[{"Effect":"Allow","Action":["s3:PutObject","s3:ListBucket"],"Resource":["arn:aws:s3:::backups","arn:aws:s3:::backups/*"]}]}
$mc admin policy create lab backup-writer backup-writer.json
$mc admin user add lab web1-backup 'Ch4nge-me-2026-long'
$mc admin policy attach lab backup-writer --user web1-backup

9Share a file for one hour

$mc share download --expire 1h lab/backups/web1/backup-2026-10-27.tar.gz.age

10Use mc with AWS S3

$mc alias set s3 https://s3.eu-central-1.amazonaws.com AKIAEXAMPLEONLY0000 exampleSecretOnly
$mc ls s3/s0sta-lab-backups-2026

انتبه

Aliases store keys in ~/.mc/config.json — keep it private.
mirror --remove deletes objects in the target that are not in the source.
Backup users should not have delete rights (protects against ransomware); use versioning or object lock.

نصائح للحفظ

Use object lock (WORM) for backups that even an admin cannot delete for N days.
