备份和恢复 NetQ
以下各节介绍如何备份和恢复本地部署的 NetQ 数据和 VM。云部署会自动备份。
您必须使用 sudo 权限运行备份和恢复脚本。
备份您的 NetQ 数据
- 检索
vm-backuprestore.sh脚本
a. 在 NVIDIA 应用中心，登录到您的帐户。
b. 选择 NVIDIA 许可门户。
c. 从菜单中选择软件下载。
d. 点击产品系列并选择 NetQ。
e. 找到最新的NetQ 升级备份恢复文件，然后选择下载。
f. 如果出现提示，请阅读许可协议并继续下载。
- 将
vm-backuprestore.sh脚本复制到您的 NetQ 服务器
username@hostname:~$ scp ./vm-backuprestore.sh cumulus@10.10.10.10:/home/cumulus/
cumulus@10.10.10.10's password:
vm-backuprestore.sh 100% 15KB 54.0KB/s 00:00
- 登录到您的 NetQ 服务器并将脚本设置为可执行
cumulus@netq-appliance:/home/cumulus# chmod +x /usr/sbin/vm-backuprestore.sh
- 在您复制
vm-backuprestore.sh脚本的目录中，运行
cumulus@netq-appliance:~$ sudo ./vm-backuprestore.sh --backup
[sudo] password for cumulus:

Mon Feb 6 12:37:18 2024 - Starting backup of data, the backup might take time based on the size of the data
Mon Feb 6 12:37:19 2024 - Scaling static pods to replica 0
Mon Feb 6 12:37:19 2024 - Scaling all pods to replica 0
Mon Feb 6 12:37:28 2024 - Scaling all daemonsets to replica 0
Mon Feb 6 12:37:29 2024 - Waiting for all pods to go down
Mon Feb 6 12:37:29 2024 - All pods are down
Mon Feb 6 12:37:29 2024 - Creating backup tar /opt/backuprestore/backup-netq-standalone-onprem-4.9.0-2024-02-06_12_37_29_UTC.tar
Backup is successful, please scp it to the master node the below command:
sudo scp /opt/backuprestore/backup-netq-standalone-onprem-4.9.0-2024-02-06_12_37_29_UTC.tar cumulus@<ip_addr>:/home/cumulus
Restore the backup file using the below command:
./vm-backuprestore.sh --restore --backupfile /opt/backuprestore/backup-netq-standalone-onprem-4.9.0-2024-02-06_12_37_29_UTC.tar
cumulus@netq-appliance:~$
验证备份文件是否成功创建
cumulus@netq-appliance:~$ cd /opt/backuprestore/ cumulus@netq-appliance:~/opt/backuprestore$ ls backup-netq-standalone-onprem-4.9.0-2024-02-06_12_37_29_UTC.tar
恢复您的 NetQ 数据
使用您在上述步骤中创建的备份文件恢复 NetQ 数据。备份脚本的恢复选项将数据从备份文件复制到数据库，对其进行解压缩，验证恢复，并启动所有必要的服务。您不应看到因恢复操作而导致任何数据丢失。
运行恢复脚本，引用备份文件所在的目录。
如果您将 NetQ 数据恢复到 IP 地址与用于备份数据的服务器不同的服务器，则必须重新配置每个交换机上的代理作为最后一步。
cumulus@netq-appliance:~$ sudo vm-backuprestore.sh --restore --backupfile /home/cumulus/backup-netq-standalone-onprem-4.10.0-2029-02-06_12_37_29_UTC.tar
Mon Feb 6 12:39:57 2024 - Please find detailed logs at: /var/log/vm-backuprestore.log

Data restored successfully
Please follow the below instructions to bootstrap the cluster
The config key restored is EhVuZXRxLWVuZHBvaW50LWdhdGVfYXkYsagDIix2OUJhMUpyekMwSHBBaitUdTVDaTRvbVJDR3F6Qlo4VHhZRytjUUhLZGJRPQ==, alternately the config key is available in file /tmp/config-key
Pass the config key while bootstrapping:
Example(standalone): netq install standalone full interface eth0 bundle /mnt/installables/NetQ-4.12.0.tgz config-key EhVuZXRxLWVuZHBvaW50LWdhdGV3YXkYsagDIix2OUJhMUpyekMwSHBbaitUdTVDaTRvbVJDR3F6Qlo4VHhZRytjUUhLZGJRPQ==
Example(cluster): netq install cluster full interface eth0 bundle /mnt/installables/NetQ-4.12.0.tgz config-key EhVuZXRxLWVuZHBvaW50LWdhdGV3YXkYsagDIix2OUJhMUpyekMwSHBbaitUdTVDaTRvbVJDR3F6Qlo4VHhZRytjUUhLZGJRPQ==
Alternately you can setup config-key post bootstrap in case you missed to pass it during bootstrap
Example(standalone): netq install standalone activate-job config-key EhVuZXRxLWVuZHBvaW50LWdhdGV3YXkYsagDIix2OUJhMUpyekMwSHBbaitUdTVDaTRvbVJDR3F6Qlo4VHhZRytjUUhLZGJRPQ==
Example(cluster): netq install cluster activate-job config-key EhVuZXRxLWVuZHBvaW50LWdhdGV3YXkYsagDIix2OUJhMUpyekMwSHBbaitUdTVDaTRvbVJDR3F6Qlo4VHhZRytjUUhLZGJRPQ==
In case the IP of the restore machine is different from the backup machine, please reconfigure the agents using: https://docs.nvda.net.cn/networking-ethernet-software/cumulus-netq/Installation-Management/Install-NetQ/Install-NetQ-Agents/#configure-netq-agents-using-a-configuration-file
