Understanding Email Archiving versus Backup

Let's kick things off by diving into the world of email data management.

To make informed decisions, it's crucial to understand the differences between email archiving versus backup.

While both methods help preserve critical information, they serve distinct purposes with unique benefits and limitations.

Purpose of email archiving

Email archiving is all about long-term retention of electronically stored information (ESI), ensuring that your organization's valuable emails remain accessible for years to come.

This approach helps maintain compliance with regulations, simplifies eDiscovery processes, and reduces storage space requirements through de-duplication and compression techniques.

Purpose of email backup

Backups focus on short-term protection against data loss due to system failures or human errors.

The primary goal here is disaster recovery - being able to quickly restore lost or corrupted emails from a recent snapshot without impacting user productivity too much.

In essence, while both strategies aim at preserving important email communications in one way or another; each has its specific use cases depending on an organizations needs.

Benefits of Email Archiving: A Game Changer for Large Organizations

Email archiving solutions are not just about storing emails. They offer a plethora of benefits that traditional email backup systems simply can't match. Let me break it down for you:

  • Successful Archiving: Email archiving offers instant and successful archiving of all email communications. This ensures that all electronically stored information is permanently stored and easily accessible. In many cases this is called email journaling
  • Long-Term Retention: With email archiving, retention policies can be set to ensure that all emails are stored for a specific period of time. This eliminates the need for mailbox quotas and ensures that all emails are available for long-term retention.
  • Disaster Recovery: In the event of a disaster, email archiving ensures that all emails are safe and can be restored. This reduces the risk of data loss and ensures that all email data is protected.
  • Email Backup Solutions: Email archiving solutions may also offer backup solutions, of sorts. 

So, why choose email archiving over traditional backup systems? Email archiving offers a range of benefits that traditional backup systems simply can't match. With email archiving, all emails are stored and easily accessible, ensuring that all electronically stored information is safe and secure. 

Limitations of Email Backups

Let's face it, backups have their shortcomings. While they can be a lifesaver in certain situations, there are some drawbacks that decision-makers should consider before relying solely on this method for preserving crucial email data.

Overwritten Previous Snapshots

Traditional backups can have the effect of replacing earlier versions with more recent ones as time passes. This might not seem like a big deal at first glance, but it could lead to the permanent loss of unrecovered emails if you're not careful.

Risky Full Restorations

Backup solutions often require full database restorations when recovering lost or corrupted messages - and let me tell you, this process isn't always smooth sailing. In fact, during these restorations, there's a chance your organization may experience data loss.

So What Can We Do?

There are alternatives available that help mitigate these limitations while still providing robust protection for your valuable electronically stored information (ESI).

Email archiving solutions, for example, offer instant access to archived emails without the need for risky full restorations or overwriting previous snapshots.

A Word of Caution...

It's important to remember that email backups and archiving serve different purposes, so don't toss out your backup strategy just yet. Instead, consider combining both approaches to ensure comprehensive protection for your organization's email communications - because when it comes to safeguarding valuable data, two is always better than one.

Use Cases for Each Approach: Email Archiving vs. Backup

Let's delve into the details to see when each approach is most suitable for various circumstances in order to make a well-informed decision about email archiving and backup solutions.

When to Use Email Archiving

Email archiving is essential when your organization needs long-term retention of electronically stored information (ESI) such as emails and attachments. This method comes in handy for complying with industry regulations like HIPAA or SEC Rule 17a-4, which require specific retention policies for certain types of data. 

When to Use Email Backup

Email backup solutions are perfect if you're looking for short-term protection against data loss due to hardware failures, human errors, or cyberattacks like ransomware infections. A successful backup strategy ensures quick disaster recovery by restoring lost or corrupted emails from recent backups without affecting other users' mailboxes.

Finding the Right Balance Between Both Strategies

Different organizations have unique requirements that may call for one solution over another - or even a combination of both. Understanding your organization's specific needs, regulatory requirements, and email data volume will help you choose the most appropriate approach for managing email communications effectively.

In the end, it all comes down to finding the right balance between archiving and backup strategies that best suit your organization's unique needs.

Combining Both Strategies for Optimal Results

So, you've learned about email archiving and backup. Now it's time to combine these two approaches for the ultimate data protection strategy.

Let's dive into how large organizations can benefit from using both approaches simultaneously.

Achieving Comprehensive Protection

Email archiving offers instant access to archived emails while ensuring long-term retention and compliance with regulations. On the other hand, email backups provide a safety net against data loss in case of server crashes or user errors. 

By combining these two strategies, you can achieve comprehensive protection for your organization's email communications.

Align your email archiving and backup strategies with your organization's retention policies to ensure a smooth, hassle-free experience. Uncover the equilibrium between these two techniques to craft a strong data handling plan that fits your needs.

Choosing the Right Archive Appliance: Key Factors to Consider

Some organizations may go down the route of implementing archiving or backup in an on-premise solution. It's a traditional data backup solution which many veteran IT professionals will be familiar with. There are many things to consider if you go down this path:

  • Data Security: Look for features like encryption and access control management to protect sensitive information from unauthorized users.
  • User Role Definition Capabilities: Ensure your chosen solution allows you to define user roles for better access control management - essential in large organizations with multiple departments or teams handling different aspects of email communications.
  • Ease of Use & Integration: Opt for a system that is easy-to-use with seamless integration into existing IT infrastructure. This will save time and resources during implementation while ensuring minimal disruption to daily operations.
  • Email Retention Policies Compliance: Select an archiving solution that supports customizable retention policies according to industry-specific regulations.
  • Sufficient Storage Space & Scalability: Last but not least, make sure there's enough storage space available within the appliance itself. Your chosen solution should also be scalable so it can grow alongside your organization's needs over time.

An email archiving system might also help you eliminate mailbox quotas if your user population is using on-premise Microsoft Exchange. This might also mean that you do not need to expand your email server or your estate of email servers in the future. However, if you're already using, or plan to use, Microsoft 365 then there might be other options to consider, rather than an on-premise solution.


Implementing Cloud-Based Solutions

As the digital landscape evolves, so do our data management strategies, this is especially true when it comes to email archiving and backup. That's where cloud-based solutions come in - a modern approach to email archiving and backup that offers flexibility and scalability.

Some organizations might need help in choosing between on-premise or a cloud based email archiving system. If your organization needs help, check out this article.


Overall, it is important for decision makers and leadership teams in large organizations to understand the differences between email archiving versus backup.
