Using S3 to store backups

The Trilio charms now support using an S3 compatible storage service to store backups. This is achieved by setting the backup-target-type option of the trilio-data-mover and trilio-wlm charms to S3 and set the following configuration options to provide information regarding the S3 service:

  • tv-s3-endpoint-url the URL of the S3 storage (can be omitted if using AWS)

  • tv-s3-secret-key the secret key for accessing the S3 storage

  • tv-s3-access-key the access key for accessing the S3 storage

  • tv-s3-region-name the region for accessing the S3 storage

  • tv-s3-bucket the S3 bucket to use to storage backups in

  • tv-s3-ssl-cert the SSL CA to use when connecting to the S3 service

See DeploymentGuideTrilio for more details.

Warning

Switching between S3 and NFS backups types is not supported or tested.
