To take a backup of your PostgreSQL database using PGBackRest and store it in an Amazon S3 bucket, you can follow these general steps:
-
Set up an Amazon S3 bucket to store your backups. Make sure you have the necessary access keys and permissions to access the bucket.
-
Create a PGBackRest configuration file (
pgbackrest.conf) that specifies the S3 bucket as the backup storage location. Here’s an example configuration:
[global]
log-level-console=info
repo1-path=/pgbackrest
repo1-retention-full=2
repo1-retention-archive=1
repo1-s3-bucket=<bucket_name>
repo1-s3-endpoint=<s3_endpoint>
repo1-s3-key=<access_key>
repo1-s3-key-secret=<access_secret>
repo1-s3-region=<region>
repo1-s3-uri-style=path
-
Replace
<bucket_name>with the name of your S3 bucket,<s3_endpoint>with the endpoint URL for your S3 region,<access_key>and<access_secret>with your AWS access key and secret access key, and<region>with your S3 region. -
Run the following command to perform a full backup and store it in the S3 bucket:
pgbackrest backup --type=full --target=s3:<backup_directory>
-
-
Replace
<backup_directory>with the directory path in the S3 bucket where you want to store the backup. -
Monitor the backup progress by looking at the output of the command. PGBackRest provides detailed information about the backup progress, including the size of the backup, the number of files being backed up, and the backup speed.
-
Once the backup is complete, you can verify it by running the
pgbackrest infocommand with the--output=jsonoption to display the backup information in JSON format.
Note that these are general steps, and the exact command and options may differ depending on your specific needs and environment. For more detailed instructions and examples, you can refer to the PGBackRest documentation.
