Remote backup storage options¶

Common options¶

storage.type¶

Type: string
Required: YES

Remote backup storage type. Supported values: s3, filesystem, azure.

S3 type storage options¶

storage:
  type: s3
  s3:
    region: <string>
    bucket: <string>
    prefix: <string>
    endpointUrl: <string>
    credentials:
      access-key-id: <your-access-key-id-here>
      secret-access-key: <your-secret-key-here>
      session-token: <string>
    uploadPartSize: <int>
    maxUploadParts: <int>
    storageClass: <string>
    serverSideEncryption:
      sseAlgorithm: aws:kms
      kmsKeyID: <your-kms-key-here>
      sseCustomerAlgorithm: AES256
      sseCustomerKey: <your_encryption_key>
    retryer:
      numMaxRetries: 3
      minRetryDelay: 30
      maxRetryDelay: 5

storage.s3.provider¶

Type: string
Required: NO

The storage provider’s name.

Supported values: aws, gcs

storage.s3.bucket¶

Type: string
Required: YES

The name of the storage bucket. See the AWS Bucket naming rules and GCS bucket naming guidelines for bucket name requirements.

storage.s3.region¶

Type: string
Required: YES (for AWS and GCS)

The location of the storage bucket. Use the AWS region list and GCS region list to define the bucket region

storage.s3.prefix¶

Type: string
Required: NO

The path to the data directory on the bucket. If undefined, backups are stored in the bucket root directory

storage.s3.endpointUrl¶

Type: string
Required: YES (for MinIO and GCS)

The URL to access the bucket. The default value for GCS is https://storage.googleapis.com

storage.s3.forcePathStyle¶

Type: boolean
Required: NO

By default, PBM uses the path-style URLs for accessing the S3 bucket. Setting this option to false instructs PBM to send virtual-hosted–style requests instead.

storage.s3.credentials.access-key-id¶

Type: string
Required: YES

Your access key to the storage bucket. This option can be omitted when you run Percona Backup for MongoDB using an EC2 instance profile. To learn more, refer to Automate access to S3 buckets for Percona Backup for MongoDB

storage.s3.credentials.secret-access-key¶

Type: string
Required: YES

The key to sign your programmatic requests to the storage bucket. This option can be omitted when you run Percona Backup for MongoDB using an EC2 instance profile. To learn more, refer to Automate access to S3 buckets for Percona Backup for MongoDB

storage.s3.credentials.session-token¶

Type: string
Required: NO

The AWS session token used to validate the temporary security credentials for accessing the S3 storage.

storage.s3.uploadPartSize¶

Type: int
Required: NO

The size of data chunks in bytes to be uploaded to the storage bucket. Default: 10MB

Percona Backup for MongoDB automatically increases the uploadPartSize value if the size of the file to be uploaded exceeds the max allowed file size. (The max allowed file size is calculated with the default values of uploadPartSize * maxUploadParts and is appr. 97,6 GB).

The uploadPartSize value is printed in the pbm-agent log.

By setting this option, you can manually adjust the size of data chunks if Percona Backup for MongoDB failed to do it for some reason. The defined uploadPartSize value overrides the default value and is used for calculating the max allowed file size

storage.s3.maxUploadParts¶

Type: int
Required: NO
Default: 10,000

The maximum number of data chunks to be uploaded to the storage bucket. Default: 10,000

By setting this option, you can override the value defined in the AWS SDK.

It can be useful when using an S3 provider that supports a smaller number of chunks for multipart uploads.

The maxUploadParts value is printed in the pbm-agent log.

storage.s3.storageClass¶

Type: string
Required: NO

The storage class assigned to objects stored in the S3 bucket. If not provided, the STANDARD storage class will be used. This option is available in Percona Backup for MongoDB as of v1.7.0.

storage.s3.debugLogLevels¶

Type: string
Required: NO

Enables S3 debug logging for different types of S3 requests. S3 log messages are printed in the pbm logs output.

Supported values are: LogDebug, Signing, HTTPBody, RequestRetries, RequestErrors, EventStreamBody.

To specify several event types, separate them by comma. To lean more about the event types, see the documentation

When undefined, no S3 debug logging is performed.

storage.s3.insecureSkipTLSVerify¶

Type: bool
Required: NO
Default: False

Disables the TLS verification of the S3 storage. This allows Percona Backup for MongoDB to upload data to S3-like storages that use self-issued TLS certificates. Available in Percona Backup for MongoDB as of version 1.7.0.

Warning

Use this option with caution as it might leave a hole for man-in-the-middle attacks.

Server-side encryption options¶

serverSideEncryption.sseAlgorithm¶

Type: string
Required: NO

The key management mode used for server-side encryption with the encryption keys stored in AWS KMS.

Supported value: aws:kms

serverSideEncryption.kmsKeyID¶

Type: string
Required: NO

Your customer-managed key stored in the AWS KMS.

serverSideEncryption.sseCustomerAlgorithm¶

Type: string
Required: NO

The key management mode for server-side encryption with customer-provided keys (SSE-C).

Supported value: AES256

serverSideEncryption.sseCustomerKey¶

Type: string
Required: NO

Your custom encryption key. This key is not stored on the S3 storage side. Thus, it is your responsibility to track what data is encrypted with what key and for storing the key.

Upload retry options¶

retryer.numMaxRetries¶

Type: int
Required: NO
Default: 3

The maximum number of retries to upload data to S3 storage. A zero value means no retries will be performed. Available in Percona Backup for MongoDB as of 1.7.0.

retryer.minRetryDelay¶

Type: time.Duration
Required: NO
Default: 30

The minimum time (in ms) to wait till the next retry. Available in Percona Backup for MongoDB as of 1.7.0.

retryer.maxRetryDelay¶

Type: time.Duration
Required: NO
Default: 5

The maximum time (in minutes) to wait till the next retry. Available in Percona Backup for MongoDB as of 1.7.0.

Filesystem storage options¶

storage:
  type: filesystem
  filesystem:
    path: <string>

storage.filesystem.path¶

Type: string
Required: YES

The path to the backup directory

Microsoft Azure Blob storage options¶

storage:
  type: azure
  azure:
    account: <string>
    container: <string>
    prefix: <string>
    credentials:
      key: <your-access-key>

storage.azure.account¶

Type: string
Required: YES

The name of your storage account.

storage.azure.container¶

Type: string
Required: YES

The name of the storage container. See the Container names for naming conventions.

storage.azure.prefix¶

Type: string
Required: NO

The path (sub-folder) to the backups inside the container. If undefined, backups are stored in the container root directory.

storage.azure.credentials.key¶

Type: string
Required: YES

Your access key to authorize access to data in your storage account.
