先按照velero 软件
velero install --provider aws --plugins velero/velero-plugin-for-aws:v1.2.1 --bucket ys-dev-k8s-bak-1307155645 \
--secret-file ./credentials-velero \
--use-restic \
--default-volumes-to-restic \
--backup-location-config \
region=ap-beijing,s3ForcePathStyle="true",s3Url=https://cos.ap-beijing.myqcloud.com
或者
velero install --provider aws --plugins velero/velero-plugin-for-aws:v1.8.1 --use-volume-snapshots=false --bucket ys-dev-k8s-bak-1307155645 --secret-file ./credentials-velero --backup-location-config region=ap-beijing,s3ForcePathStyle="true",s3Url=https://cos.ap-beijing.myqcloud.com --use-node-agent
#配置文件说明
vim credentials-velero ###是对象存储的认证文件

安装完成查看
指定命名空间备份
velero backup create dmp-dev-backup --include-namespaces dmp-dev
velero backup create dmp-dev-backup --include-namespaces dmp-dev
Backup request "dmp-dev-backup" submitted successfully.
Run `velero backup describe dmp-dev-backup` or `velero backup logs dmp-dev-backup` for more details.
# 查看备份的进度
velero backup describe dmp-dev-backup --details
查看备份
备份完毕
查看备份是否有错误
velero backup logs dmp-test-backup | grep error
指定应用的备份
恢复
将备份存储位置临时更新为只读模式(可以防止在还原过程中，velero在备份存储位置中创建或删除备份对象)
kubectl patch backupstoragelocation default --namespace velero \
--type merge \
--patch '{"spec":{"accessMode":"ReadOnly"}}' \
backupstoragelocation.velero.io/default patched
执行恢复命令
velero restore create --from-backup dmp-dev-backup
##会显示如下内容
Restore request "dmp-dev-backup-20220630094836" submitted successfully.
Run `velero restore describe dmp-dev-backup-20220630094836` or `velero restore logs dmp-dev-backup-20220630094836` for more details.
查看恢复
velero restore get
#查看恢复进度
velero restore describe dmp-dev-backup-20220630094836 --details
