cinder 备份提供了三种驱动服务: Ceph,TSM,Swift 其中默认备份驱动服务为swift
cinder 驱动服务的配置在cinder.conf文件中
backup_driver=cinder.backup.drivers.swift
Ceph的配置
backup_driver = cinder.backup.drivers.ceph backup_ceph_conf=/etc/ceph/ceph.conf backup_ceph_user = cinder backup_ceph_chunk_size = 134217728 backup_ceph_pool = backups backup_ceph_stripe_unit = 0 backup_ceph_stripe_count = 0
为了挂载 Cinder 块设备(块设备或者启动卷),必须告诉 Nova 挂载设备时使用的用户和 uuid 。libvirt会使用该用户来和 Ceph 集群进行连接和认证。
rbd_user = cinder
rbd_secret_uuid = 457eb676-33da-42ec-9a8c-9293d545c337
完整版Ceph的配置:
backup_driver = cinder.backup.drivers.ceph
backup_ceph_conf=/etc/ceph/ceph.conf
backup_ceph_user = cinder
backup_ceph_chunk_size = 134217728
backup_ceph_pool = backups
backup_ceph_stripe_unit = 0
backup_ceph_stripe_count = 0
rbd_user = cinder
rbd_secret_uuid = 457eb676-33da-42ec-9a8c-9293d545c337
TSM的配置
backup_driver = cinder.backup.drivers.tsm backup_tsm_compression = True (BoolOpt) 启用或禁用压缩备份 backup_tsm_password = password (StrOpt) 运行TSM用户的密码(节点密码) backup_tsm_volume_prefix = backup (StrOpt) 当备份到TSM时备份标识id的卷前缀
backup_driver = cinder.backup.drivers.swift backup_swift_url = http://localhost:8080/v1/AUTH backup_swift_auth = per_user backup_swift_user = <None> backup_swift_key = <None> backup_swift_container = volumebackups backup_swift_object_size = 52428800 backup_swift_retry_attempts = 3 backup_swift_retry_backoff = 2 backup_compression_algorithm = zlib
代码分析
backup(/cinder/backup/) /cinder/backup/__init__.py:指定并导入cinder-backup的API类; /cinder/backup/api.py:处理所有与卷备份服务相关的请求; class API(base.Base):卷备份管理的接口API,主要定义了卷的备份相关的三个操作的API: create:实现卷的备份的建立; delete:实现删除卷的备份; restore:实现恢复备份; 这三个操作都需要通过backup_rpcapi定义的RPC框架类的远程调用来实现; /cinder/backup/driver.py:所有备份驱动类的基类; class BackupDriver(base.Base):所有备份驱动类的基类; /cinder/backup/manager.py:卷备份的管理操作的实现; class BackupManager(manager.SchedulerDependentManager):块存储设备的备份管理;继承自类 SchedulerDependentManager; 主要实现的是三个远程调用的方法: create_backup:实现卷的备份的建立(对应api.py中的creat方法); restore_backup:实现恢复备份(对应api.py中的restore方法); delete_backup:实现删除卷的备份(对应api.py中的delete方法); /cinder/backup/drivers/ceph.py:ceph备份服务实现; class CephBackupDriver(BackupDriver):Ceph对象存储的Cinder卷备份类;这个类确认备份Cinder卷到Ceph对象存储系统; /cinder/backup/drivers/swift.py:用swift作为后端的备份服务的实现; class SwiftBackupDriver(BackupDriver):用swift作为后端的备份服务的各种管理操作实现类; /cinder/backup/drivers/tsm.py:IBM Tivoli存储管理(TSM)的备份驱动类; class TSMBackupDriver(BackupDriver):实现了针对TSM驱动的卷备份的备份、恢复和删除等操作;
具体操作
创建卷 cinder create --display-name volume1 1 备份卷 cinder backup-create --container volumes_backup --display-name backuptoswift volume1 恢复卷 cinder backup-restore --volume-id cb0fe233-f9b6-4303-8a61-c31c863ef7ce volume1 删除卷 cinder backup-delete 1b9237a4-b384-4c8e-ad05-2e2dfd0c698c
