Install and configure AWS Backint Agent for SAP HANA - SAP HANA on AWS

Install and configure AWS Backint Agent for SAP HANA

This section provides information to help you install the AWS Backint agent using an AWS Systems Manager document or AWS Backint installer. It also provides information to help you configure the agent, view logs, and get the current agent version.

Install AWS Backint agent using the AWS Systems Manager document

Use the following steps to install the AWS Backint agent using the AWS SSM document.

Important

Disable any existing backup processes (including scheduled log backups) before continuing with the installation. If you don’t disable existing backup processes before executing the SSM document, you can corrupt an in-progress backup, which can impact your ability to recover your database.

  1. From the AWS Management Console, choose Systems Manager under Management & Governance, or enter Systems Manager in the Find Services search bar.

  2. From the Systems Manager console, choose Documents under Shared Resources in the left navigation pane.

  3. On the Documents page, select the Owned by Amazon tab. You should see a document named AWSSAP-InstallBackint.

  4. Select the AWSSAP-InstallBackint document and choose Run command.

  5. Under the Command parameters, enter the following

    1. Bucket Name. Enter the name of the Amazon S3 bucket where you want to store your SAP HANA backup files.

    2. Bucket Folder. Optionally, enter the name of the folder within your Amazon S3 bucket where you want to store your SAP HANA backup files.

    3. System ID. Enter your SAP HANA System ID, for example HDB.

    4. Bucket Region. Enter the AWS Region of the Amazon S3 bucket where you want to store your SAP HANA backup files. AWS Backint agent supports cross-Region and cross-account backups. You must provide the AWS Region and Amazon S3 bucket owner account ID along with the Amazon S3 bucket name for the agent to perform successfully.

    5. Bucket Owner Account ID. Enter the account ID of the Amazon S3 bucket where you want to store your SAP HANA backup files.

    6. Kms Key. Enter the ARN of KMS key that AWS Backint agent can use to encrypt the backup files stored in your Amazon S3 bucket.

    7. Installation Directory. Enter the path of the directory location where you want to install the AWS Backint agent. Avoid using /tmp as the install path.

    8. Agent Version. Enter the version number of the agent that you want to install. If you do not enter a version number, the latest published version of the agent is installed.

      Note

      1.0 versions are unavailable in the GovCloud Regions.

    9. Modify Global ini file. Choose how you want to modify the global.ini file. The global.ini file of the SAP HANA SYSTEM DB must be updated to complete the setup.

      1. “modify” — SSM will update the global.ini file directly.

      2. “sql” — SSM will create a file called modify_global_ini.sql with SQL statements that you can run in your target SAP HANA system to set the required parameters. You can find the modify_global_ini.sql file in the <installation directory>/aws-backint-agent/ folder.

      3. “none” — No action will be taken by SSM to modify the global.ini file. You must manually update it to complete the setup.

    10. Ignore Bucket Checks. Select yes to ignore sanity checks of the S3 bucket. S3 Bucket sanity checks verify the following:

      • the bucket exists in your account

      • the bucket Region is correct

      • the bucket is public

    11. Debug Mode. Select yes to activate debug mode.

    12. Important! Ensure No Backup In Process. Choose Yes to confirm that you have disabled existing backups and are ready to proceed with the installation. The SSM document will fail if you choose “No”.

  6. Under Targets, select the method for your target instance to use to install the AWS Backint agent, and then choose the instance on which to install it. If you are not able to find your instance in the list, verify that you have followed all of the steps in the prerequisites.

  7. Under Other parameters, leave the field empty and choose Run.

    Important

    If you do not have the latest version of the SSM Agent installed (2.3.274.0 or later), Run Command will fail to execute.

  8. When the agent is successfully installed, you will see the Success status under the Command ID.

  9. To verify the installation, log in to your instance and view the /<install directory>/aws-backint-agent directory. You should see the following files in the directory: the AWS Backint agent binary, THIRD_PARTY_LICENSES.txt file, which contains licenses of libraries used by the agent, the launcher script, the YAML configuration file, and the optional modify_global_ini.sql file. In addition, a source file (aws-backint-agent.tar.gz) of AWS Backint agent is stored in the package directory. You can verify the signature of this file to ensure that the downloaded source file is original and unmodified. See the Verifying the signature of AWS Backint agent and installer for SAP HANA section in this document for details.

    The SSM document creates symbolic links (symlinks) in the SAP HANA global directory for the Backint configuration. Verify that the symlink for hdbbackint exists in the /usr/sap/<SID>/SYS/global/hdb/opt directory and the symlink for aws-backint-agent-config.yaml exists in the /usr/sap/<SID>/SYS/global/hdb/opt/hdbconfig directory.

Install AWS Backint agent using AWS Backint installer — interactive mode

Another way to install the AWS Backint agent is with the AWS Backint installer. You can download the AWS Backint installer from an Amazon S3 bucket. The name of the S3 bucket is s3://awssap-backint-agent/.

Note

For AWS GovCloud (US-East), the name of the S3 bucket is s3://awssap-backint-agent-us-gov-east-1.

For AWS GovCloud (US-West), the name of the S3 bucket is s3://awssap-backint-agent-us-gov-west-1.

The latest installer can always be found at s3://awssap-backint-agent/binary/latest/install-aws-backint-agent .

Note

For AWS GovCloud (US-East), the latest installer can always be found at s3://awssap-backint-agent-us-gov-east-1/binary/latest/install-aws-backint-agent.

For AWS GovCloud (US-West), the latest installer can always be found at s3://awssap-backint-agent-us-gov-west-1/binary/latest/install-aws-backint-agent.

Follow these steps to install AWS Backint agent using the AWS Backint installer from an SSH session on your SAP HANA instance.

Important

Disable any existing backup processes (including scheduled log backups) before continuing with the installation. If you don’t disable existing backup processes before executing the AWS Backint agent installer, you can corrupt an in-progress backup, which can impact your ability to recover your database.

  1. Navigate to /tmp (or another temporary directory where you downloaded the installer).

    cd /tmp
  2. Run one of the following commands to download the installer.

    sudo aws s3 cp s3://awssap-backint-agent/binary/latest/install-aws-backint-agent /tmp/

    or

    sudo wget https://s3.amazonaws.com/awssap-backint-agent/binary/latest/install-aws-backint-agent -O /tmp/install-aws-backint-agent
    Note

    If you encounter permission issues while downloading the AWS Backint installer using the AWS CLI, check your IAM policy and ensure that your policies allow for downloading objects from the awssap-backint-agent bucket. See the Identity and Access Management section of this documentation for details.

  3. (Optional) For AWS GovCloud (US-East) and AWS GovCloud (US-West), run one of the following commands to download the installer.

    sudo aws s3 cp s3://awssap-backint-agent-us-gov-east-1/binary/latest/install-aws-backint-agent /tmp/
    sudo aws s3 cp s3://awssap-backint-agent-us-gov-west-1/binary/latest/install-aws-backint-agent /tmp/

    or

    sudo wget https://awssap-backint-agent-us-gov-east-1.s3.us-gov-east-1.amazonaws.com/binary/latest/install-aws-backint-agent -O /tmp/install-aws-backint-agent
    sudo wget https://awssap-backint-agent-us-gov-west-1.s3.us-gov-west-1.amazonaws.com/binary/latest/install-aws-backint-agent -O /tmp/install-aws-backint-agent
  4. Run the installer with the -h flag to find all of the available options.

    sudo python install-aws-backint-agent -h
  5. Run the following command to execute the installer.

    sudo python install-aws-backint-agent
    Note

    Run the installer with the -l flag if you want the installer to get the AWS Backint agent binary file from your own file system or Amazon S3 bucket. Specify the location of the aws-backint-agent.tar.gz file.

    sudo python install-aws-backint-agent -l /tmp/backint/aws-backint-agent.tar.gz
    sudo python install-aws-backint-agent -l s3://AWSDOC-EXAMPLE-BUCKET/aws-backint-agent.tar.gz
    sudo python install-aws-backint-agent -l https://AWSDOC-EXAMPLE-BUCKET.s3.amazonaws.com/aws-backint-agent.tar.gz
  6. Enter information for the following parameters.

    1. Installation directory — Enter the path of the directory location where you want to install the AWS Backint agent. The default value for the installation directory is /hana/shared/.

    2. Amazon S3 bucket owner — Enter the account ID of the Amazon S3 bucket owner of the bucket where you want to store your SAP HANA backup files.

    3. Amazon S3 bucket Region — Enter the AWS Region of the Amazon S3 bucket where you want to store your SAP HANA backup files.

    4. Amazon S3 bucket name — Enter the name of the Amazon S3 bucket where you want to store your SAP HANA backup files.

    5. Folder in the S3 bucket — Enter the name of the folder in the Amazon S3 bucket where you want to store your SAP HANA backup files. This parameter is optional.

    6. Amazon S3 SSE KMS ARN — Enter the ARN of the KMS key that AWS Backint agent can use to encrypt the backup files stored in your Amazon S3 bucket.

      Note

      If you leave this field empty, AWS Backint installer will prompt you to confirm that you don’t want to encrypt your backup files with encryption keys stored in AWS KMS. If you do not confirm that you do not want to encrypt with the KMS key, the installer will abort. We strongly recommend that you encrypt your data. See the Encryption section of this documentation for available options.

    7. SAP HANA system ID — Enter your SAP HANA System ID, for example HDB.

    8. HANA opt dir — Confirm the location of the SAP HANA opt directory.

    9. Modify global.ini [modify/sql/[none]] — Choose how you want to modify the global.ini file. The global.ini file of the SAP HANA SYSTEM must be updated to complete the setup.

      1. “modify” — AWS Backint installer will update the global.ini file directly.

      2. “sql” — AWS Backint installer will create a file called modify_global_ini.sql with SQL statements that you can run in your target SAP HANA system to set the required parameters. You can find the modify_global_ini.sql file in the <installation directory>/aws-backint-agent/ folder.

      3. “none” — No action will be taken by AWS Backint installer to modify the global.ini file. You must manually update them to complete the setup.

    10. HANA SYSTEM db global.ini file — Confirm the location of global.ini file.

    11. Verify signature of the agent binary .tar file

      • Choose y to verify the signature of the AWS Backint agent source file. If you choose y, enter the Amazon S3 bucket location of the signature file of the agent binary .tar file, for example, https://s3.amazonaws.com/awssap-backint-agent/binary/latest/aws-backint-agent.sig. Or, provide a local file that is stored on the instance. If you proceed without making a selection, the default location listed within brackets ([]) is used.

      • Choose n if you do not want to verify the signature of the AWS Backint agent source file.

    12. Save responses for future usage? — You can save your information for the AWS Backint installer to a file. You can then use it later to run the installer in silent mode, if needed.

    13. Do you want to proceed with the installation? — Confirm that you have disabled the existing backups and are ready to proceed with the installation.

  7. To verify the installation, log in to your instance and view the /<install directory>/aws-backint-agent directory. You should see the following files in the directory: the AWS Backint agent binary, the THIRD_PARTY_LICENSES.txt file, which contains licenses of libraries used by the agent, the launcher script, the YAML configuration file, and the optional modify_global_ini.sql file. In addition, a source file (aws-backint-agent.tar.gz) of AWS Backint agent is stored in the package directory. You can verify the signature of this file to ensure that the downloaded source file is original and unmodified. See the Verifying the signature of AWS Backint agent and installer for SAP HANA section in this document for details.

    In addition, the AWS Backint installer creates symbolic links (symlinks) in the SAP HANA global directory for the Backint configuration. Verify that the symlink for hdbbackint exists in the /usr/sap/<SID>/SYS/global/hdb/opt directory, and that the symlink for aws-backint-agent-config.yaml exists in the /usr/sap/<SID>/SYS/global/hdb/opt/hdbconfig directory.

    Note

    If your installation fails due to validation errors and you want to ignore the validation and proceed with the installation, you can execute the installer with the -n flag to ignore the validation steps. You can also use the -d flag to run the installer in debug mode to generate detailed installation logs for troubleshooting.

Install AWS Backint agent using AWS Backint installer — silent mode

You can install the AWS Backint agent with the AWS Backint installer in a silent mode. Choose this option if you want the installation process to be automated without manual intervention.

To run the AWS Backint installer in silent mode, create a response file with all of the required installation parameters. Follow the steps in the section on installing using the interactive mode to download AWS Backint installer and create a response file. You don’t have to confirm to continue with the AWS Backint agent installation in interactive mode. AWS Backint installer will create a response file called aws-backint-agent-install-YYYYMMDDHHMMSS.rsp.

When you have a response file, you can modify it with a vim editor and adjust the parameters as needed.

The following is an example response file.

[DEFAULT] s3_bucket_name = awsdoc-example-bucket s3_bucket_owner_account_id = 111122223333 modify_global_ini = sql s3_bucket_region = us-east-1 s3_sse_kms_arn = arn:aws:kms:us-east-1:111122223333:key/1abcd9b9-ab12-1a2a-1abc-12345abc12a3 s3_bucket_folder = myfolder hana_sid = TST installation_directory = /hana/shared/

If you want to generate the response file programmatically instead of using AWS Backint installer in interactive mode, you can use the -g flag to generate a new response file. The following is an example of how to generate a response file using AWS Backint installer.

sudo python install-aws-backint-agent -g "s3_bucket_owner_account_id = 111122223333,s3_bucket_name = awsdoc-example-bucket,s3_bucket_region = us-east-1,hana_sid = TST,s3_sse_kms_arn = arn:aws:kms:us-east-1:111122223333:key/1abcd9b9-ab12-1a2a-1abc-12345abc12a3,s3_bucket_folder = myfolder,installation_directory = /hana/shared/,modify_global_ini = sql" -f myresponse.rsp

After the response file is created, use the following steps to run AWS Backint installer in silent mode.

Important

Disable any existing backup processes (including scheduled log backups) before continuing with the installation. If you don’t disable existing backup processes before executing the AWS Backint agent installer, you can corrupt an in-progress backup, which can impact your ability to recover your database.

Run the following command to execute the installer using the generated response file.

sudo python install-aws-backint-agent -m silent -f backint-agent-install-YYYYMMDDHHMMSS.rsp -a yes

If you want to choose the location from which to install the agent, run the command with the -l flag and specify the location.

sudo python install-aws-backint-agent -f aws-backint-agent-install-YYYYMMDDHHMMSS.rsp -m silent -a yes -d -l /tmp/backint/aws-backint-agent.tar.gz
Note

You must confirm that you have disabled the existing backups and are ready to proceed with the installation in silent mode by passing an acknowledgement flag (-a yes). If you don’t pass the acknowledgement flag, AWS Backint installer will fail to execute.

Use a proxy address with AWS Backint agent

If you use a proxy address in your SAP HANA environment when you install the agent, you must use the following shell script to install the agent to ensure that the correct proxy settings are used by the AWS Backint agent installer.

#!/bin/bash export https_proxy=<PROXY_ADDRESS>:<PROXY_PORT> export HTTP_PROXY=<PROXY_ADDRESS>:<PROXY_PORT> export no_proxy=169.254.169.254 export NO_PROXY=169.254.169.254 sudo python install-aws-backint-agent

If you use a proxy address in your SAP HANA environment, you must update the aws-backint-agent-launcher.sh file, which is located in the AWS Backint agent installation directory (for example, /hana/shared/aws-backint-agent/). You must perform the following update to ensure that the correct proxy settings are used by AWS Backint agent during backup and restore operations.

Add http_proxy, HTTP_PROXY, no_proxy, and NO_PROXY variables to the aws-backint-agent-launcher.sh script. It is important to exclude the 196.254.169.254 address with the no_proxy variable. If you do not exclude this address, instance metadata service calls made by AWS Backint agent will fail and cause errors during backup and restore operations. For more information about instance metadata and user data, see Instance metadata and user data in the Amazon EC2 User Guide for Linux Instances.

#!/bin/bash export https_proxy=<PROXY_ADDRESS>:<PROXY_PORT> export HTTP_PROXY=<PROXY_ADDRESS>:<PROXY_PORT> export no_proxy=169.254.169.254 export NO_PROXY=169.254.169.254 /hana/shared/aws-backint-agent/aws-backint-agent "$@"

Backint-related SAP HANA parameters

To enable SAP HANA backups using AWS Backint agent, you must set the following SAP HANA parameters. If you chose the “modify” option for the global.ini file update, the SSM document or AWS Backint installer adds or updates the following backup related SAP HANA parameters in global.ini for the system database. If you chose “sql”, you can run the SQL statements specified in the modify_global_ini.sql file to update these parameters. For more details about these parameters, see Backup Configuration Parameters in the SAP HANA Administration Guide.

[backup] catalog_backup_parameter_file = /usr/sap/<SID>/SYS/global/hdb/opt/hdbconfig/aws-backint-agent-config.yaml data_backup_parameter_file = /usr/sap/<SID>/SYS/global/hdb/opt/hdbconfig/aws-backint-agent-config.yaml log_backup_parameter_file = /usr/sap/<SID>/SYS/global/hdb/opt/hdbconfig/aws-backint-agent-config.yaml catalog_backup_using_backint = true log_backup_using_backint = true parallel_data_backup_backint_channels = 8 data_backup_buffer_size = 4096 max_recovery_backint_channels = 1 [communication] tcp_backlog = 2048 [persistence] enable_auto_log_backup = yes verify_signature = yes input_signature_filepath = https://s3.amazonaws.com/awssap-backint-agent/binary/latest/aws-backint-agent.sig
Note

Changing the tcp_backlog parameter requires a restart of SAP HANA to take effect.

max_recovery_backint_channels determines the number of log files restored/recovered in parallel during the recovery process. When multistreamed backups are recovered, SAP HANA always uses the same number of channels that were used during the backup. For more information, see Multistreaming Data Backups with Third-Party Backup Tools in the SAP documentation.

Modify AWS Backint agent configuration parameters

The AWS Backint agent configuration parameters are maintained in a YAML file in the /<installation directory>/aws-backint-agent/ directory. The name of the configuration file is aws-backint-agent-config.yaml.

If you want to change the location of AWS Backint agent logs, you can update the parameter LogFile in the aws-backint-agent-config.yaml file.

Get the currently installed AWS Backint agent version

To display the backint version and the current AWS Backint agent version that it supports, run the hdbbackint command with the –v parameter from the install directory as the <SID>adm user as shown in the following example.

/usr/sap/<SID>/SYS/global/hdb/opt/hdbbackint -v

Update or install a previous version of AWS Backint agent

The agent and installer are released together and their versions will always match. The latest and previous versions of the installer can be found at the following S3 bucket locations:

  • Latest version s3://awssap-backint-agent/binary/latest/install-aws-backint-agent

    AWS GovCloud (US-East) latest version s3://awssap-backint-agent-us-gov-east-1/binary/latest/install-aws-backint-agent

    AWS GovCloud (US-West) latest version s3://awssap-backint-agent-us-gov-west-1/binary/latest/install-aws-backint-agent

  • Previous version s3://awssap-backint-agent/binary/agent-version/install-aws-backint-agent

    AWS GovCloud (US-East) previous versions3://awssap-backint-agent-us-gov-east-1/binary/agent-version/install-aws-backint-agent

    AWS GovCloud (US-West) previous versions3://awssap-backint-agent-us-gov-west-1/binary/agent-version/install-aws-backint-agent

To install a previous version of the installer, download the version you want to install from the S3 folder that contains the previous version.

Note

The installer will download and install the version of the agent that corresponds to the installer version.

When you install the agent using the SSM document, you can input the version you want to install.

Performance tuning

AWS Backint agent is installed with default values that optimize the performance of backup and restore operations. If you want to further optimize the performance of your backup and restore operations, you can adjust the UploadChannelSize and MaximumConcurrentFilesForRestore parameters. Ensure that you are using the right instance type and storage configurations to get the best performance. AWS Backint agent is constrained by the resources available in the instance.

The UploadChannelSize parameter is used to determine how many files can be uploaded in parallel to the S3 bucket during backups. The default value for this parameter is 10 and it provides optimal performance in most cases.

The UploadConcurrency parameter is used to determine how many S3 threads can work in parallel during backups. The default value for this parameter is 100 and it provides optimal performance in most cases.

The MaximumConcurrentFilesForRestore parameter is used to determine how many files can be downloaded in parallel from S3 during a restore operation. The default value for this parameter is 5, which provides the optimal performance for most use cases.

If you want to adjust these parameters, you can add them to the aws-backint-agent-config.yaml file and adjust the values (up to the allowed maximum). We strongly recommend that you test both the backup and recovery operations after the change to ensure there is no unintended impact to your backup and restore operations, as well as to other standard operations.

Additionally, to get the best performance during backup and restore operations, ensure that your SAP HANA data and log volumes are configured following the best practices from AWS. See the Storage Configuration for SAP HANA section in the SAP HANA on AWS documentation for more details.
