Data Retention Policy: The TL;DR

A Data Retention Policy is your organization's rulebook for managing, storing, and disposing of data. It's the who, what, where, when, and why of data management, outlining:

- What types of data to keep

- How long to keep it

- How to securely get rid of it when it's time

Lets see more details and how it fits to the overall data governance for Microsoft 365.

What is a Data Retention Policy?

At its core, a Data Retention Policy is all about two things: preserving data and destroying data. Data preservation is about deciding how long to keep different types of data around. Maybe financial records need to stick around for 7 years as expected by the auditors. Data destruction is about getting rid of data that's past its prime. No one needs last year's lunch invite emails clogging up the system for example.

So why bother with a Data Retention Policy? It's like a game plan for managing data day in and day out. By laying down the law, you're lowering the risk of legal trouble and making sure you're not wasting space on useless data.

What Should a Data Retention Policy Include?

A robust Data Retention Policy comprises a series of key elements and is part of the bigger picture of Data Governance in Microsoft 365. Make sure to include:

Third-party backup solutions that can protect and back up data across Microsoft 365, such as Exchange Online, SharePoint Online, OneDrive for Business, and Microsoft Teams.

Identify all the different flavors of data you're working with, such as financial, personal, operational, and transactional data. Different data types need varied durations of retention. For instance, financial data might be retained for seven years, aligning it with typical audit cycles.

Outline the storage methods for digital and physical data, guaranteeing secure and accessible storage. Bonus points for adherence to globally recognized security standards like ISO 27001.  

Provide clear instructions for successful data disposal post-retention. Mentioning secure deletion methods, such as data wiping, ensures residual data removal.

Some data might not need to be front and center, but you still need it sometimes. Proper archiving can prevent unnecessary data retrieval, saving time and resources.

Define strategies for different disaster scenarios, such as data loss, service disruption, or complete datacenter failure. Documented step-by-step procedures for executing recovery processes, including data restoration, service failover, and communication protocols.

Regularly test your recovery plans to ensure their effectiveness during times of need.

Develop a thorough incident response plan that details roles, duties, and communication procedures for addressing and handling incidents or disasters.

Keep an eye on Microsoft 365 services to detect and alert on potential issues or service degradation within Microsoft 365 services.

Reflect the legal obligations your organization must adhere to - be they statutory, industry-specific, or contractual. GDPR, for instance, imposes notable data retention requirements.

Assign roles for policy enforcement, like Data Protection Officers, clarifying their duties and obligations. This allocation enforces accountability.

Give consistent instruction to end-users, IT staff, and stakeholders regarding disaster recovery protocols, data protection guidelines, and their roles and duties. Keep documentation current for disaster recovery plans, procedures, configurations, and contact details.

Why is a Data Retention Policy Important in Microsoft 365?

Data retention goes beyond mere preservation; it's a key tool for achieving operational effectiveness within Microsoft 365.  

First, it helps foster compliance with regulatory requirements. Say, for instance, you're obligated to follow GDPR regulations. A specifically outlined Data Retention Policy aids in structuring stored data in alignment with GDPR's principles, directly helping you stay on the right side of the law.

Secondly, a robust Data Retention Policy plays a decisive role in reducing legal liabilities. Take, for example, a scenario where a confidentiality agreement breach occurs. Having specified erasure guidelines in the policy can create a line of defense against potential heavy fines you might otherwise face.

Another important advantage is the safeguarding of confidential information from unauthorized persons. Recent cybercrime data indicates a concerning rise in data breaches. By integrating strict storage and security protocols into your Data Retention Policy, you can effectively protect yourself from potential risks.

Finally, Data integrity and availability hold the key to optimal business operations. The integrity ensures that your data remains consistent and accurate over its entire life-cycle. On the other hand, data availability ensures that data is always accessible when needed. For instance, a well thought out archiving rule in your policy ensures important emails are not permanently deleted, hence maintaining necessary data availability.

Microsoft 365 Data Retention Policy Essentials

Let's investigate some of the intricacies of Microsoft 365 data retention policies with Exchange Online, SharePoint Online, OneDrive for Business, and Microsoft Teams.

What is the retention policy in Office 365?

Microsoft 365 does not have a single, standardized data retention policy that applies across all services. Instead, each service has its own default data retention period and capabilities for customizing data retention policies.

Data Retention in Exchange Online

Exchange Online, a key feature of Microsoft 365, provides retention policies that enable users to set the duration of email data storage. Microsoft suggests retaining email messages in Exchange Online for a minimum of 30 days prior to deletion. You have the option to establish a retention policy to keep emails for a certain duration, like 1 year or 7 years.

For instance, you work in a heavily regulated sector that requires email storage for a period of 7 years. Instead of manually managing each mailbox, set a default retention policy in Exchange Online. Once you set the policy, Exchange Online serves as a steward of data, proactively purging emails that pass their retention period.

With Alcion you can enhance the data retention capabilities for your email data by setting up automated backups and defining granular retention periods, giving you an extra layer of protection and control over your Exchange Online data.

Data Retention for SharePoint Online and OneDrive

By default, SharePoint Online and OneDrive for Business keep files for at least 30 days before deleting them. While SharePoint's retention labels offer a native solution for preserving critical files, they have limitations when it comes to comprehensive data protection. Learn more about SharePoint Online backup challenges and solutions.

OneDrive leverages similar strategies to SharePoint. For example, when managing a project with a closeout date 3 years in the future, applying a retention label ensures project documents maintain availability until that date, aiding seamless data retrieval. However, these native features may not provide sufficient protection against all data loss scenarios.

With Alcion, you can schedule regular backups and set retention points that align with your organization's policies and compliance requirements. This ensures that your critical data is always protected and recoverable, even in the event of data loss or corruption.

Teams Chat and Conversations Retention

Microsoft Teams, the collaboration hub, raises unique retention challenges due to the variety of data types, including private chats, channel conversations, and meetings. Microsoft recommends keeping Teams data (including chat messages, channel conversations, and meeting recordings) for at least 7 days before deleting it.

Imagine you need to retain all private chats for litigation purposes for 2 years. Teams fulfills this by applying custom retention policies, ensuring legal compliance, transparency, and ease of data management.  

With Alcion, you can define retention periods for your Teams backups, ensuring that your chat history, channel conversations, and meeting data are preserved in accordance with your organization's policies and legal requirements.

Understanding the Impact of Data Retention on Storage and Costs in Microsoft 365

Data retention inevitably leads to an increased demand for storage space. As the volume of retained data grows, organizations may need to plan for additional storage capacity in Microsoft 365 to accommodate this increase. This can affect both your on-premises environments and cloud storage, impacting the overall infrastructure footprint.

Alcion helps mitigate the impact of data retention on storage and costs by offering a cost-effective and scalable backup solution. With Alcion's intelligent backup scheduling, custom and granular retention policies, you can optimize your storage usage and minimize the costs associated with retaining large volumes of data. Alcion's cloud-based architecture ensures that your backups are stored securely and efficiently, without the need for additional on-premises infrastructure.

Retention policies can cause an uptick in the quantity of stored emails, documents, and chat logs, which can escalate storage requirements. Versioning in SharePoint Online and OneDrive for Business means multiple iterations of documents are kept, further enhancing storage needs. Strategically archiving data can mitigate some storage concerns, keeping the most essential data readily available and offloading other data to less accessible, less costly storage.

Managing your Data Retention Policy is a balancing act between meeting legal requirements and optimizing costs. Organizations must be mindful of the costs that come with increased storage needs and align them with their retention strategies. Implement policies that differentiate between types of data – some might require quick access and reside in premium storage, while other data can be archived in more cost-effective storage solutions.  

Understanding Your Data Retention Needs

Identifying the data you store carries weight. These may comprise emails, files, or chats. Each data type holds distinctive retention requirements. Best data retention policies stem from recognizing the nature of your data. Conversely, ignoring data specifics leads to policy inefficacy, if not failure.

First, consider the diverse kinds of data under your control. Emails, for instance, often bear vital business information and relevant communications. Retaining these records becomes inevitable. Also, files could encapsulate a range of information, from spreadsheets to archived projects. They're essential in tracing the chronology of your projects. Last, chats serve as informal yet significant business communication channels. They may not command the authority of formal emails but offer valuable data nonetheless.

When structuring a data retention policy, regulatory requirements present a significant factor. Be mindful of industry laws and guidelines about data retention. In the healthcare sector, for instance, HIPAA enforces a minimum seven-year record retention period. Similar laws apply to the financial sphere, where SEC rules demand a five-year data retention period for brokerage records. Staying informed about these legal mandates becomes crucial. Not doing so risks compliance violations and potential penalties.

Apart from legalities, business considerations mold your data retention policy as well. Storing irrelevant data for too long invites unnecessary storage costs and clutter. Yet, prematurely discarding pertinent data poses its own risks. Striking the right balance depends on your unique business needs. A robust retention policy respects both your regulatory obligations and your operational necessities, without leaning excessively towards either.

Best Practices for Implementing a Data Retention Policy in Microsoft 365

To form a data retention policy that's both efficient and compliant, one can't overlook the involvement of key stakeholders. IT, compliance, legal, and business teams all play crucial roles in the formation of this policy. They not only assure that the policy aligns with organizational needs, but also ensure it satisfies regulatory requirements.

For a vivid example, consider a pharmaceutical company. They must adhere to the Food and Drug Authorities (FDA) regulations, which stipulates retaining certain data for five years. In such a case, the legal and compliance teams would assist in setting up a policy that conforms to such specific requirements, while IT teams could carry out these rules within Microsoft 365 systems.

More than creating a well-informed policy, it's equally key to keep it current and adaptable. Monitor and review the policy on a regular basis. This frequent check aids in quickly implementing any new regulations that emerge. For instance, the General Data Protection Regulation (GDPR) introduced in 2018 mandated stringent rules for data of European Union citizens. Regular reviews of your data retention policy would help accommodate such regulations in your existing systems swiftly.

Besides, monitoring also accounts for any changes in business needs. With the current pace of technological advancement, businesses constantly evolve and so do their data retention requirements. Hence, ensuring your policy stays updated is essential for its efficiency and effectiveness.

Implementing data retention policies efficiently across your organization can be challenging. Group Based Policy Management (GBPM) offers a solution to apply and manage policies at scale, especially for large tenancies.
