EPAS(DBaaS) is a relational database management system (RDBMS) with high compatibility with Oracle databases. Samsung Cloud Platform provides an environment that can automate EPAS installation and perform management functions for operation through a web-based Console.
EPAS (DBaaS) is designed as a high‑availability architecture that performs storage‑based data replication and minimizes failover time. To prevent data loss, when the contents of the Active server change, they are synchronously replicated to the Standby server, and up to five read‑only Replica servers for read load balancing and disaster recovery (DR) are provided. Additionally, to prepare for potential issues with the DB server or data, we provide an automatic backup feature at user-specified times, enabling data recovery at the desired point in time.

Provided features
EPAS(DBaaS) provides the following features.
Auto Provisioning: It allows installation and configuration of Database (DB) through the UI, and provides an Active‑standby redundancy configuration built on storage replication. * When the active server fails, it automatically fails over to standby.
Operation Control Management: Provides a function to control the status of running servers. * In addition to start and stop, a restart is possible if there is a DB issue or to apply configuration changes. * When high availability (HA) is configured, a node transition between Active-Standby can be performed directly by the user through a switch-over.
Backup and Recovery: Provides data backup functionality based on its own backup commands. * Backup time windows and storage locations can be configured by the user, and additional fees may apply based on the backup size. * It also provides a recovery feature for backed‑up data; when the user initiates a recovery, a separate database is created, and the recovery proceeds to the point in time selected by the user (the backup creation time or a user‑specified time). * When restoring to a user-specified point in time, the restore point can be set up to 5 minutes, 10 minutes, 30 minutes, or 1 hour prior to the stored backup and archive files.
Version Management: Provides Minor version upgrade functionality based on some feature improvements and security patches. * Whether to perform a backup for a version upgrade can be selected by the user, and if a backup is performed, the data is backed up before applying the patch, after which the DB engine is updated.
Replica configuration: Up to five Read Replicas can be configured in the same or different regions for read load balancing and disaster recovery (DR).
Audit configuration: Provides an Audit configuration feature that can monitor users’ DB access and the results of DDL (Data Definition Language)/DML (Data Manipulation Language) operations.
Parameter Management: Performance improvement and security-related DB configuration parameters can be modified.
Service Status Query: Retrieves the final status of the current DB service.
Monitoring: CPU, memory, performance monitoring information can be viewed through Cloud Monitoring and Servicewatch.
DB User Management: View and manage the DB account (user) information registered in the DB.
DB Access Control Management: Based on DB accounts registered in the DB, you can register and revoke allowed IPs for access.
Archive Management: You can set the Archive file retention period (1~35 days) on the DB server and configure the Archive mode (On/Off).
DB Log Export: You can export stored logs to the user’s Object Storage via Audit settings.
Migration: Synchronizes data in real time with the operational database and supports migration using replication without service interruption.
OS Kernel Upgrade: You can upgrade the OS Kernel to apply some feature improvements and security patches.
Components

Additionally, to efficiently manage disk space, we provide an option that exports logs to Object Storage while automatically deleting the original log files. By using this option, you can effectively free up storage capacity while safely retaining the necessary log data for the long term.
안내
To use the DB Log export feature, you need to create an Object Storage. * For Object Storage creation, please refer to the Object Storage 사용자 가이드.
Please be sure to verify the expiration date and time of the authentication key. * If the authentication key expires, logs will not be stored in the bucket.
Please ensure that authentication key information is not exposed to external parties.

2.2 - Backing up and restoring the DB
Users can configure backups for EPAS (DBaaS) through the Samsung Cloud Platform Console and restore using the backed‑up files.
EPAS(DBaaS) Backing up
To ensure that user data is stored securely, EPAS (DBaaS) provides a data backup feature based on its own backup commands. Additionally, you can verify whether the backup was successful using the backup history feature, and you can also delete backed-up files.
Configure Backup
Refer to EPAS(DBaaS) 생성하기 for how to configure backup settings for EPAS (DBaaS).
To modify the backup settings of a created resource, follow the steps below.
Caution
For reliable backups, we recommend adding separate BACKUP storage or sufficiently expanding storage capacity. * Especially when the backup data exceeds 100 GB and experiences frequent changes, please secure additional storage equal to about 60 % of the data size. * For storage addition and expansion methods, please refer to the guides EPAS(DBaaS) 스토리지 추가하기, EPAS(DBaaS) 스토리지 증설하기.
If a backup is configured, it runs at the specified time after the set time, and additional fees apply based on the backup size.
If you change the backup setting to Unset, backup execution will stop immediately, and the stored backup data will be deleted and can no longer be used.
To set up a backup, follow these steps.
All Services > Database > EPAS(DBaaS) Click the menu. 1. Navigate to the Service Home page of EPAS (DBaaS).
On the Service Home page, click the EPAS(DBaaS) menu. 2. Navigate to the EPAS(DBaaS) List page.

Recover EPAS(DBaaS)
If a failure or data loss occurs and restoration from a backup file is required, recovery can be performed based on a specific point in time using the recovery feature. When you perform EPAS (DBaaS) recovery, a new server is created with the OS image from the initial provisioning point, the database is installed with the version from the backup point, and recovery proceeds with the database’s configuration information and data.

2.4 - EPAS (DBaaS) server connection
Scenario Overview
EPAS(DBaaS) Server Connection scenario creates a Bastion host (Virtual Server) and a Database service, and accesses the DB service through the Bastion host. To reliably connect to EPAS (DBaaS) in the Samsung Cloud Platform environment, you need to create a Bastion host and establish a network connection using it. To maintain stability and a high level of security, we recommend configuring the Database service in a Private Subnet environment and setting up the Bastion host in a restricted Public Subnet environment.
This scenario primarily describes creating a Bastion host and Database service, configuring the network environment for Bastion host and Database access, and connecting through a DB client.
