备份/恢复用例

milvus-backup 工具的应用较为广泛，可以在多种用例中使用，具体使用场景取决于您的需求和配置：

  1. 在同一个 Milvus 实例内进行备份和恢复：在同一 Milvus 实例内将 Collection 复制为一个新的 Collection。

  2. 在共用同一个 S3 Bucket 的两个 Milvus 实例之间进行备份和恢复：在使用不同根路径但使用相同 S3 Bucket 的 Milvus 实例之间迁移 Collection。

  3. 在同一个 S3 服务不同 Bucket 的两个 Milvus 实例之间进行备份和恢复：在同一 S3 服务内的不同 S3 Bucket 之间迁移 Collection。

  4. 在不同 S3 服务的两个 Milvus 实例之间进行备份和恢复：在使用不同 S3 服务的 Milvus 实例之间复制 Collection。

让我们详细探讨每个用例。

用例 1：在同一个 Milvus 实例内进行备份和恢复

在同一个 Milvus 实例内针对一个 Collection 进行备份和恢复。假设我们需要为名称为 “coll” 的 Collection 创建备份并将其恢复为名称为 “coll_bak” 的 Collection。这个过程中，我们使用同一个 S3 Bucket。

配置：

  • Milvus使用 bucket_A 作为存储

  • MinIO 配置：

minio:
 address: localhost # Address of MinIO/S3
 port: 9000 # Port of MinIO/S3
 accessKeyID: minioadmin # accessKeyID of MinIO/S3
 secretAccessKey: minioadmin # MinIO/S3 encryption string
 useSSL: false # Access to MinIO/S3 with SSL
 ssl:
   tlsCACert: /path/to/public.crt # path to your CACert file, ignore when it is empty
 bucketName: bucket_A # Bucket name in MinIO/S3
 rootPath: files # The root path where the message is stored in MinIO/S3

备份和恢复流程

配置 backup.yaml 文件将 Milvus 和 MinIO 指向正确的位置。

minio:
 # cloudProvider: "minio" # deprecated use storageType instead
 storageType: "minio" # support storage type: local, minio, s3, aws, gcp, ali(aliyun), azure, tc(tencent)
 address: localhost # Address of MinIO/S3
 port: 9000   # Port of MinIO/S3
 accessKeyID: minioadmin  # accessKeyID of MinIO/S3
 secretAccessKey: minioadmin # MinIO/S3 encryption string
 useSSL: false # Access to MinIO/S3 with SSL
 useIAM: false
 iamEndpoint: ""
 bucketName: "bucket_A" # Milvus Bucket name in MinIO/S3, make it the same as your milvus instance
 rootPath: "files" # Milvus storage root path in MinIO/S3, make it the same as your milvus instance

 # only for azure
 backupAccessKeyID: minioadmin  # accessKeyID of MinIO/S3
 backupSecretAccessKey: minioadmin # MinIO/S3 encryption string
  backupBucketName: "bucket_A" # Bucket name to store backup data. Backup data will store to backupBucketName/backupRootPath
 backupRootPath: "backup" # Rootpath to store backup data. Backup data will store to backupBucketName/backupRootPath

通过以下命令创建备份。

./milvus-backup create -c coll -n my_backup

上述命令将备份文件存储在 bucket_A/backup/my_backup 中。

将备份恢复至新 Collection。

./milvus-backup restore -c coll -n my_backup -s _bak

上述命令将 Collection “coll” 恢复为同一个 Milvus 实例中的新 Collection “coll_bak”。

图1: 在同一个 Milvus 实例内进行备份和恢复的流程

用例 2：在共用同一个 S3 Bucket 的两个 Milvus 实例之间进行备份和恢复

从一个 Milvus 实例备份一个 Collection，使用相同的 S3 桶但不同的根路径将其恢复到另一个实例。假设在 milvus_A 中有一个名为 “coll” 的 Collection，我们将其备份并恢复到 milvus_B 中名为 “coll_bak” 的新 Collection 中。这两个 Milvus 实例共享同一个 S3 Bucket “bucket_A”，但这两个 Milvus 实例的根路径不同。

配置

  • Milvus A 使用 files_A 作为根路径

  • Milvus B 使用 files_B 作为根路径

  • Milvus A 的 MinIO 配置：

minio:
 address: localhost # Address of MinIO/S3
 port: 9000 # Port of MinIO/S3
 accessKeyID: minioadmin # accessKeyID of MinIO/S3
 secretAccessKey: minioadmin # MinIO/S3 encryption string
 useSSL: false # Access to MinIO/S3 with SSL
 ssl:
   tlsCACert: /path/to/public.crt # path to your CACert file, ignore when it is empty
 bucketName: bucket_A # Bucket name in MinIO/S3
 rootPath: files_A # The root path where the message is stored in MinIO/S3
  • Milvus B 的 MinIO 配置：
minio:
 address: localhost # Address of MinIO/S3
 port: 9000 # Port of MinIO/S3
 accessKeyID: minioadmin # accessKeyID of MinIO/S3
 secretAccessKey: minioadmin # MinIO/S3 encryption string
 useSSL: false # Access to MinIO/S3 with SSL
 ssl:
   tlsCACert: /path/to/public.crt # path to your CACert file, ignore when it is empty
 bucketName: bucket_A # Bucket name in MinIO/S3
 rootPath: files_B # The root path where the message is stored in MinIO/S3
