What are the Backup Types?

Full Backup: A full backup creates a complete copy of all your data in one operation. This is comprehensive but can take up a lot of time and storage space.

Synthetic Full Backup: This method starts with a full backup and integrates subsequent incremental backups to keep the full backup current without re-copying all the data. It uses the backup server’s resources, not the system being backed up.

Differential Backup: A differential backup copies all the data that has changed since the last full backup. It captures new or modified files, making it more efficient than a full backup while still ensuring data is up-to-date.

Incremental Backup: This type only backs up data that has changed since the last backup, whether it was a full or incremental one. It’s efficient in terms of storage and time, as it doesn’t duplicate unchanged data.

Continuous Data Protection (CDP): CDP, or real-time backup, continuously saves every change made to your data, capturing every version and ensuring nothing is lost.

Snapshot Backup: A snapshot backup captures an exact image of your system, application, or disk at a specific point in time, providing a full copy that can be restored if needed.

Bare Metal Backup (BRM): Bare-metal backup allows you to restore your entire system, including the operating system, applications, and data, to new hardware after a severe failure.

VM Recovery: VM recovery involves restoring a virtual machine (VM) to its previous state, including its OS, applications, data, and services, using a backup of the VM.

Volume Recovery: This method restores a specific data volume to its previous state, ideal for recovering from partial data losses.

File-level Recovery: File-level recovery focuses on restoring individual files that have been lost or corrupted, without needing to restore the entire system.

Replication: Replication involves copying and moving backup data to different locations. There are two types:

  • Synchronous Replication: Data is written to both primary and secondary storage simultaneously.
  • Asynchronous Replication: Data is first written to primary storage and then copied to secondary storage afterward.

Cloud backup: Cloud backup  is a service that replicates your company’s data to cloud-based storage and can be used for disaster recovery or to keep a copy of your data off-site.

What data should be backed up and how frequently?

What data should be backed up

  1. Critical Business Data

    • Customer Databases

    • Financial Records

    • Employee Information

    • Intellectual Property

  2. Operational Data

    • Email and Communication Records

    • Project Files and Documents

    • Application Data

    • Configuration Files

  3. Legal and Compliance Data

    • Compliance Documents: 

    • Audit Trails

  4. System and Network Data

    • System Backups:

    • Network Configurations

How frequently

  1. Critical Business Data

    • Daily Backups: Ensure minimal data loss and quick recovery in case of an issue.

    • Real-Time Backups: For highly critical data, like financial records and customer databases, continuous data protection (CDP) can be ideal.

  2. Operational Data

    • Daily Backups: Important for data that changes frequently, such as email and active project files.

    • Weekly Backups: Suitable for less critical operational data that doesn’t change as frequently.

  3. Legal and Compliance Data

    • Daily or Weekly Backups: Depending on the volume and frequency of changes, regular backups ensure compliance and legal readiness.

  4. System and Network Data

    • Weekly or Monthly Backups: System and network configurations typically do not change daily, so weekly or monthly backups are often sufficient.

    • After Major Changes: Always perform a backup after any significant system or network changes or updates.

Backup Appliances vs. Backup Software?

Backup appliances are all-in-one solutions that combine hardware and software designed specifically for backing up data. Think of them as dedicated devices that you can set up in your office to handle all your backup needs and Backup software is a program you install on your existing hardware to manage your data backups. This software can be used on servers, desktops, or even laptops.

Which Should You Choose?

  • Backup Appliances: Ideal if you want a turnkey solution that is easy to deploy and manage. Great for businesses that prefer an all-in-one device with robust security and performance.
  • Backup Software: Best if you need flexibility and have existing hardware to leverage. Suitable for businesses that want to customize their backup solution and are comfortable managing the software and hardware separately.
Backup Appliances vs. Backup Software

Frequently Asked Questions

Backups protect against human errors, hardware failure, virus attacks, power failure, and natural disasters. 

Data backup and recovery refers to the process of making and keeping backup copies of electronic information and recovering them.

Unlike backups, archive data is not copied, but moved to less expensive storage. This frees up storage space on the expensive primary storage.

Data is backed up to an on-site server, a backup appliance or a data center off-site (or even a combination of all three).
