MBR tool

mbr is a tool written in go which is a wrapper around mc

mbr host add src http://minio1:9000/ ACCESSKEY SECRETKEY
mbr host add tgt http://minio2:9000/ ACCESSKEY SECRETKEY

mbr snapshot tag src tgt/BUCKET/PREFIX/
mbr restore tag tgt/BUCKET/PREFIX src
mbr list tgt/BUCKET/PREFIX <tag>
mbr delete tgt/BUCKET/PREFIX <tag>
mbr delete tgt/BUCKET/PREFIX all --force

mbr snapshot tag src tgt/BUCKET/PREFIX/

This list all the buckets and all the files recursively and stores in a tag.yaml file:

bucket1:
  - name: object1
    etag: ETAG1
  - name: object2
    etag: ETAG2
  - name: object3
    etag: ETAG3
bucket2:
  - name: object4
    etag: ETAG4
  - name: object5
    etag: ETAG5
  - name: object6
    etag: ETAG6
bucket3:
  - name: object7
    etag: ETAG7
  - name: object8
    etag: ETAG8
  - name: object9
    etag: ETAG9

mbr stores tag.yml in tgt/BUCKET/PREFIX/mbr/tags/ mbr then mirrors everything in src into tgt/BUCKET/PREFIX/mbr/snapshots/ like this:

tgt/BUCKET/PREFIX/mbr/snapshots/bucket1/object1
tgt/BUCKET/PREFIX/mbr/snapshots/bucket1/object2
tgt/BUCKET/PREFIX/mbr/snapshots/bucket1/object3
tgt/BUCKET/PREFIX/mbr/snapshots/bucket2/object4
tgt/BUCKET/PREFIX/mbr/snapshots/bucket2/object5
tgt/BUCKET/PREFIX/mbr/snapshots/bucket2/object6
tgt/BUCKET/PREFIX/mbr/snapshots/bucket3/object7
tgt/BUCKET/PREFIX/mbr/snapshots/bucket3/object8
tgt/BUCKET/PREFIX/mbr/snapshots/bucket3/object9

mbr restore tag tgt/BUCKET/PREFIX src

This restores all the contents of tag from tgt/BUCKET/PREFIX to src

mbr list tgt/BUCKET/PREFIX

If tag is not specified, it lists all the tags. If tag is specified it lists the contents of tag.yml

mbr delete tgt/BUCKET/PREFIX

This deletes the particular snapshot identified by tag - i.e it deletes all the files referenced only in this snapshot.

mbr delete tgt/BUCKET/PREFIX all --force

This deletes everything inside tgt/BUCKET/PREFIX
