What is a Database Backup?
Data backup is one of the key measures for data protection, ensuring its preservation even in emergency situations.
The primary goal of backup is to ensure data recovery in its most up-to-date state, minimizing information loss.
What Problems Does Data Backup Solve?
Protection against data loss
Protection from cyberattacks
Migration to new systems
Minimizing downtime
Types of Database Backups
☑️ Full backup: A complete copy of all data. This process is time-consuming but provides a full snapshot of the data.
☑️ Differential backup: Captures changes made since the last full backup.
☑️ Incremental backup: Records only the changes made since the last backup (full, incremental, or differential).
☑️ Transaction log backups: Saves the sequence of changes for recovery to a specific point in time.
How to Perform Data Backup for Different Databases?
MS SQL Server
Backing up data in MS SQL Server can be done via Management Studio or SQL queries. For automation, SQL Server Agent is used.
PostgreSQL
In PostgreSQL, the utilities pg_dump and pg_dumpall are employed for backups. Automation can be achieved through scripts and cron jobs on Linux. Additionally, we use the pgBackRest tool, which allows automatic uploading of backups to cloud storage.
Oracle
For Oracle, backups are performed using the RMAN (Recovery Manager) utility. Automation is also supported through Oracle Enterprise Manager.
Database Restoration from Backup
Restoring a database from a backup is a complex and critical task that requires not only technical skills but also a deep understanding of the system and data structure.
Restoration is more than just deploying the data; it involves several steps, each of which can be critical to successful recovery.
Key Stages in Data Restoration
Stage 1
Choosing the right backup: The most recent backup is not always the best choice. It is essential to consider the timing of the last successful backup and the state of the data at the time of failure. Choosing the wrong backup can lead to partial or complete data loss.
Stage 2
Preparing the environment: Database restoration requires setting up the working environment, which may include:
- Ensuring sufficient disk space.
- Disconnecting active users to avoid conflicts during the restoration process.
- Ensuring software version compatibility (e.g., SQL Server, PostgreSQL, Oracle).
Stage 3
Restoration process: The process depends on the type of backup used. A full backup may take considerable time and resources, while differential or incremental backups require the correct restoration sequence — full backup first, followed by differential or incremental. Mistakes in this sequence can make data recovery impossible.
Stage 4
Data integrity check: After restoration, it is crucial to verify that the data is not corrupted, all transactions are completed correctly, and the database structure is intact. This requires running tests and data integrity checks. Ensuring the data has been restored in full and matches its pre-issue state is essential.
Stage 5
Minimizing downtime: Data recovery can take a long time, especially if the database is large or has complex structures. For businesses, this means downtime and potential losses, making the minimization of recovery time a critical factor. In some cases, restoring to a standby server or using technologies that reduce recovery time is necessary.
Stage 6
Working with transaction logs: For some databases (e.g., SQL Server and Oracle), transaction logs play an important role in the restoration process. They enable restoring the database to a specific point in time, minimizing data loss even after an incident.
Professional database recovery from backups is a multi-layered process where errors or oversights can lead to significant data loss or cause the database to malfunction. Therefore, in complex situations requiring high accuracy and risk minimization, it is recommended to consult experts.
When Do You Need Expert Help?
Issues with Recovery After a Failure
During critical moments such as system failures or hardware malfunctions, timely data recovery is crucial for minimizing losses. Mistakes in backup configuration can make the recovery process impossible, which is why expert assistance is essential.
Transitioning to Complex Backup Systems
As data volumes grow, simple backup strategies become insufficient. Incorrect configuration of incremental or differential backups can result in data loss, and only experts can properly design such systems.
Backup Automation for Large Systems
Large enterprises require automated backup processes. Setting up regular monitoring, backup rotation, and alert systems demands a professional approach to mitigate risks.
Integration with Multiple Databases
When working with multiple systems like MS SQL, PostgreSQL, or Oracle, it’s vital to account for their unique features when creating a unified backup strategy. Only specialists can ensure proper integration.
