This commit adds support for Backup and Restore controller, which will be watching for
the events. The velero plugin will create a Backup CR to create a backup
with the remote location information, the controller will send the data
to that remote location.
In the same way, the velero plugin will create a Restore CR to restore the
volume from the the remote location and the restore controller will restore
the data.
Steps to use velero plugin for ZFS-LocalPV are :
1. install velero
2. add openebs plugin
velero plugin add openebs/velero-plugin:latest
3. Create the volumesnapshot location :
for full backup :-
```yaml
apiVersion: velero.io/v1
kind: VolumeSnapshotLocation
metadata:
name: default
namespace: velero
spec:
provider: openebs.io/zfspv-blockstore
config:
bucket: velero
prefix: zfs
namespace: openebs
provider: aws
region: minio
s3ForcePathStyle: "true"
s3Url: http://minio.velero.svc:9000
```
for incremental backup :-
```yaml
apiVersion: velero.io/v1
kind: VolumeSnapshotLocation
metadata:
name: default
namespace: velero
spec:
provider: openebs.io/zfspv-blockstore
config:
bucket: velero
prefix: zfs
backup: incremental
namespace: openebs
provider: aws
region: minio
s3ForcePathStyle: "true"
s3Url: http://minio.velero.svc:9000
```
4. Create backup
velero backup create my-backup --snapshot-volumes --include-namespaces=velero-ns --volume-snapshot-locations=aws-cloud-default --storage-location=default
5. Create Schedule
velero create schedule newschedule --schedule="*/1 * * * *" --snapshot-volumes --include-namespaces=velero-ns --volume-snapshot-locations=aws-local-default --storage-location=default
6. Restore from backup
velero restore create --from-backup my-backup --restore-volumes=true --namespace-mappings velero-ns:ns1
