Backup and Restore Configurations

This page describes the configuration options available for backup and restore on TigerGraph and how to set them.

Prerequisites

You have access to the TigerGraph Linux user account on your cluster. All commands must be run from the TigerGraph Linux user.

Configuration parameters

The following is a list of configurations available for backup and restore.

[NOTE]: For System.Backup.Local.Enable, System.Backup.S3.Enable, System.Backup.ABS.Enable, and System.Backup.GCS.Enable, only one can be enabled at a time.

Configuration parameter Description Default

Configuration parameter	Description	Default
System.Backup.Local.Enable	Whether to store the database backup data to a local path.	`false`
System.Backup.Local.Path	Local path to store the backup files. Required if backup is to be stored locally.	`null`
System.Backup.S3.Enable	Enables or disables backup to AWS S3 or S3-compatible services such as Ceph S3.	`false`
System.Backup.S3.AWSAccessKeyID	AWS Access Key ID for authentication (deprecated, use System.Backup.S3.AccessKeyID instead, which has a higher priority.)	`null`
System.Backup.S3.AWSSecretAccessKey	AWS Secret Access Key for authentication (deprecated, use System.Backup.S3.SecretAccessKey instead, which has a higher priority.) [NOTE]: If setting this in interactive mode, store the key in a file and provide the path to the file, e.g., `@/tmp/test_secret`.	`null`
System.Backup.S3.AccessKeyID	Access key ID for authentication for AWS S3 or S3-compatible services.	`nan`
System.Backup.S3.SecretAccessKey	Secret Access Key for authentication for AWS S3 or S3-compatible services. [NOTE]: If setting this in interactive mode, store the key in a file and provide the path to the file, e.g., `@/tmp/test_secret`.	`nan`
System.Backup.S3.BucketName	Bucket for AWS S3 or S3-compatible services.	`nan`
System.Backup.S3.Endpoint	A URL used to interact with the S3 (AWS S3/S3-compatible) service. It can be used for AWS S3 VPC Endpoint, customer endpoint, or S3-compatible service. For regular AWS S3, leave it empty.	`nan`
System.Backup.S3.RoleARN	The AWS role for accessing s3 buckets. S3 Role ARN takes priority over access keys. For more information, see AWS role ARN documentation. [NOTE]: This is only for AWS S3, and TigerGraph assumes the credentials for using `sts:AssumeRole` have been set up. You can verify the credentials are ready by running aws sts assume-role. One way to set up credentials is to configure access key id, secret access key and region with AWS CLI `aws configure`.	`nan`

System.Backup.TimeoutSec	Timeout limit for the backup operation in seconds	`18000`
System.Backup.CompressProcessNumber	Number of concurrent processes for compression during backup. `0` means the number of processes used to compress is equal to the number of CPU cores on each node. We recommending keeping the default value `10`.	`10`

System.Backup.CompressionLevel

The backup compression level strikes a balance between size and speed. The better compression, the longer it takes. ("BestSpeed", "DefaultCompression", "BestCompression")

"DefaultCompression"

Configure backup and restore

Running gadmin config entry backup allows you to enter the value for each parameter individually.

Alternatively, you can use gadmin config set <parameter> to change the value of any parameter.

After configuring the parameters, run gadmin config apply to apply the new parameter values.

Configure System.Backup.S3.Endpoint

Typically, there’s no need to configure the System.Backup.S3.Endpoint parameter on a TigerGraph Server. This is because the system auto-detects the regional endpoint for AWS S3 backups.

Users should configure this parameter only for special cases, such as:

To backup to a AWS S3 vpc endpoint, typically set it to "https://s3.amazonaws.com/" or any available URI/VPC endpoints.
To backup to an S3-compatible service, set it to its corresponding service URI.

Except for the above specific situations, leave it empty.

Backup to AWS S3

To configure backup files to an AWS S3 Bucket for an on-premises TigerGraph Server cluster, complete the following steps:

Create an S3 bucket in AWS
Create an AWS IAM user

Create an IAM policy that ensures the IAM user has sufficient access to the bucket itself, and contents within the bucket

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": [
                "s3:PutObject",
                "s3:ListBucket",
                "s3:GetObject",
                "s3:GetBucketLocation"
            ],
            "Effect": "Allow",
            "Resource": [
                "arn:aws:s3:::<bucket-name>",
                "arn:aws:s3:::<bucket-name>/*"
            ]
        }
    ]
}

Create an AccessKeyID and SecretAccessKey for the IAM user

TigerGraph clusters use long-lived credentials to authenticate to AWS as the IAM user, allowing TigerGraph access to put backup files into the S3 bucket. These credentials are also used to read and copy files during a Restore process.

Configure each of the following parameters on the linux command line:

Enable storing backup data in S3

gadmin config set "System.Backup.S3.Enable" "true"

Specify bucket name

gadmin config set "System.Backup.S3.BucketName" "<bucket-name>"

Set S3 backup AccessKeyID

gadmin config set "System.Backup.S3.AccessKeyID" "<access-key-id>"

Set S3 backup SecretAccessKey

gadmin config set "System.Backup.S3.SecretAccessKey" "<secret-access-key>"

Alternatively, instead of using AccessKeyID and SecretAccessKey, you may use AWS Role ARN for the authentication.

gadmin config set "System.Backup.S3.RoleARN" "arn:aws:iam::account:role/role-name-with-path"

Apply the new parameter values

gadmin config apply -y

Backup to ABS (Azure Blob Storage)

Similar to backing up to AWS S3, once the Azure Blob Storage Container is created and configured properly (refer to Introduction to Azure Blob Storage), then configure it to be your backup storage via the following steps.

Enable storing backup data to ABS, and ensure other backup types are disabled.
```
gadmin config set "System.Backup.ABS.Enable" "true"
```

Specify the backup ABS Endpoint(or leave it empty if the default endpoint is okay)

gadmin config set "System.Backup.ABS.Endpoint" "https://<account-name>.blob.core.windows.net"

Specify ABS ContainerName

gadmin config set "System.Backup.ABS.ContainerName" "<container-name>"

Set ABS backup AccountName

gadmin config set "System.Backup.ABS.AccountName" "<account-name>"

Set ABS backup AccountKey

gadmin config set "System.Backup.ABS.AccountKey" "<account-key>"

Apply the new parameter values
```
gadmin config apply -y
```

Backup to GCS (Google Cloud Storage)

Similar to backing up to ABS, prepare the proper HMAC keys. Then configure it to be your backup storage via the following steps.

Enable storing backup data to GCS, and ensure other backup types are disabled.
```
gadmin config set "System.Backup.GCS.Enable" "true"
```

Specify GCS BucketName

gadmin config set "System.Backup.GCS.BucketName" "<bucket-name>"

Set GCS backup AccessKey

gadmin config set "System.Backup.GCS.AccessKey" "<access-key>"

Set GCS backup Secret

gadmin config set "System.Backup.GCS.Secret" "<secret>"

Apply the new parameter values
```
gadmin config apply -y
```
