快照
更新时间：2024-07-02
创建快照
使用以下代码可以从指定的磁盘创建快照，支持创建系统盘快照和CDS磁盘快照。
创建系统盘快照时，实例的状态必须为 Running 或 Stopped 此操作才能正常完成。
创建CDS磁盘快照时，磁盘的状态需要为InUse或 Available 此操作才能正常完成。
可创建快照数量的配额取决于账号下拥有的磁盘总数，当前最多为磁盘数量乘以8。

21 # 创建快照的磁盘ID
22 volume_id = 'v-***'
23 resp = client.create_snapshot(volume_id, snapshot_name, client_token=client_token)
24 print(resp)查询快照列表
使用以下代码以查询所有的快照信息，包括系统盘快照和数据盘快照信息：
Python
1from baidubce.auth.bce_credentials import BceCredentials
2from baidubce.bce_client_configuration import BceClientConfiguration
3from baidubce.services.bcc import bcc_client

9 SK = b'sk'
10 # 设置默认配置
11 config = BceClientConfiguration(credentials=BceCredentials(AK, SK),
12 endpoint=HOST)
13 # 创建bcc client
14 client = bcc_client.BccClient(config)
15
16 # 创建快照的磁盘ID
17 volume_id = 'v-***'
18 # 批量获取列表的查询的起始位置
19 marker = "your-marker"
20 # 每页包含的最大数量
21 max_keys = 100
22 resp = client.list_snapshots(marker=marker, max_keys=max_keys, volume_id=volume_id)
23 print(resp)查询快照详情
使用以下代码可以通过指定的快照ID查询单个快照的详细信息：
Python

12 endpoint=HOST)
13 # 创建bcc client
14 client = bcc_client.BccClient(config)
15
16 # 快照ID
17 snapshot_id = 's-EJq3B***'
18 resp = client.get_snapshot(snapshot_id)
19 print(resp)删除快照
使用以下代码可以通过指定快照ID删除快照。
只有当快照的状态为 CreatedFailed 或 Available时，操作才能正常完成：
Python
1from baidubce.auth.bce_credentials import BceCredentials

9 SK = b'sk'
10 # 设置默认配置
11 config = BceClientConfiguration(credentials=BceCredentials(AK, SK),
12 endpoint=HOST)
13 # 创建bcc client
14 client = bcc_client.BccClient(config)
15
16 # 待删除快照ID
17 snapshot_id = 's-EJq3B***'
18 resp = client.delete_snapshot(snapshot_id=snapshot_id)
19 print(resp)查询快照链列表
使用以下代码可以查询快照链列表：
Python
1from baidubce.auth.bce_credentials import BceCredentials

15
16 # 磁盘ID
17 volume_id = 'v-***'
18 resp = client.list_snapshot_chain(volume_id)
19 print(resp)快照链绑定标签
使用以下代码可以给指定快照链绑定标签：
Python
1from baidubce.auth.bce_credentials import BceCredentials
