Guide to Creating and Managing a Data Retention Policy

Matilda Bailey is a distinguished networking and data management specialist with a deep focus on how modern organizations navigate the complexities of cellular, wireless, and next-gen storage solutions. With years of experience advising firms on the intersection of technical infrastructure and regulatory compliance, she has become a leading voice in developing sustainable data lifecycle strategies. Today, we sit down with her to discuss the evolving landscape of data retention, exploring how businesses can balance the ballooning costs of storage with the rigid demands of global privacy laws and legal discovery.

The following conversation explores the critical distinctions between operational and regulatory data, the role of automation in lifecycle management, and the strategic use of diverse storage media like cloud and tape.

How do you distinguish between operational and regulatory reasons for keeping information, and what specific steps should a company take to classify data before it is eventually targeted for disposal?

Operational retention is driven by the immediate value data brings to your business, such as needing backups for disaster recovery or historical data for future analytics. In contrast, regulatory retention is a legal mandate where you are required to hold onto information—like financial reports for seven years under SOX—regardless of whether it helps your daily workflow. To classify this properly, a company must first assemble a cross-functional team including IT, legal, and department heads to identify what data they actually have. This team should categorize data by type—such as patient records versus employee emails—and then assign specific retention periods to each. Following a 10-step process that includes defining business requirements and setting up internal audits ensures that by the time data is targeted for disposal, everyone is certain it no longer holds legal or functional value.

Keeping information too long increases storage costs and legal exposure during discovery. How do you balance the cost of storage against the risk of compliance-related fines, and what metrics do you use to determine if data has lost its relevancy?

Balancing these factors requires looking at the direct costs of primary storage versus the potential multi-million dollar impact of legal exposure or compliance fines. We use relevancy metrics based on the “age of data” and its access frequency; if a file hasn’t been touched in six months, it often signals a transition point from active to archival status. By removing irrelevant data, you not only lower your storage bills but also reduce your “attack surface,” meaning there is less sensitive information available to be compromised during a breach. The goal is to retain the minimally required volume of data, which makes it faster and less expensive for auditors to locate what they need, thereby avoiding fines for failing to produce records in a timely manner.

Regulatory frameworks like SOX and HIPAA mandate specific holding periods, such as seven or six years. In these highly regulated environments, how do you manage the transition from active to archival storage while ensuring that records remain easily searchable for auditors?

In highly regulated sectors, the transition must be seamless, moving data from expensive primary tiers to cheaper, long-term archival systems once its active lifecycle ends. For instance, HIPAA requires patient data to be on file for at least six years, so we implement an archiving system that automates this lifecycle management while keeping the metadata intact. This metadata is the secret sauce—it allows a user or auditor to search through millions of archived records across different storage tiers almost as easily as if they were on a local drive. By using a repeatable and predictable process, as suggested by the U.S. Supreme Court, we demonstrate to regulators that our deletion and archiving practices are disciplined and legally sound.

Effective policy creation requires collaboration between IT, legal, and HR departments. What are the practical steps for establishing internal enforcement mechanisms, and how do you ensure that automated deletion software does not accidentally purge vital contracts or sensitive historical records?

Practical enforcement starts with creating two versions of your policy: a formal legal document and a simplified version for internal stakeholders that avoids dense jargon. To prevent “accidental purges,” we don’t just rely on age-based deletion; we use a policy engine that filters by user, department, and file type to identify high-value documents like permanent contracts. IT must work closely with HR and legal to set these rules, ensuring that the software recognizes specific “vital” flags in the metadata. Before any automated deletion occurs, administrators should perform spot checks and audits to be absolutely certain that the data being removed truly serves no further purpose for the organization.

Different storage media like object storage, public cloud, and tape offer various trade-offs in cost and restore speed. When designing a lifecycle management strategy, how do you decide which data types belong on tape versus the cloud, and what are the implications for disaster recovery?

The decision usually comes down to how fast you need that data back if something goes wrong. Object storage is fantastic for data that needs solid protection at a moderate cost, while the public cloud is ideal for off-site protection and infrequent access tiers, though restore speeds vary by data set size. Tape remains a powerhouse for historical data that is rarely accessed; it’s cheaper over many years and uses significantly less energy than spinning disks, though it has the slowest restore times. For disaster recovery, a mix is best—cloud offers quick off-site recovery for critical systems, while tape provides a physical “air-gapped” archive for long-term survival against catastrophic data loss.

Privacy laws like the GDPR and CCPA emphasize ethical use and minimizing the retention of personal information. How do you integrate these principles into an existing data management strategy, and what are the challenges of managing data produced by citizens across different geographic jurisdictions?

Integrating these laws means shifting from a “keep everything” mindset to a “data minimization” approach, where you only hold personal information for as long as it’s needed to complete a specific objective. The challenge is immense because a company in the U.S. might be subject to the GDPR if they handle data for even one EU citizen, requiring them to know exactly why and where that data is held. Laws like the CCPA and its 2023 amendment, the CPRA, don’t always set a fixed maximum number of years, but they demand that you prove your retention period is tied to a legitimate business purpose. We manage this by using geographic tags in our metadata, allowing us to apply different retention rules to data depending on where the citizen resides.

During litigation, organizations often need to pause their standard lifecycle processes through a legal hold. What specific protocols should be in place to handle these subpoenas, and how do you prevent these pauses from causing a permanent, costly buildup of unnecessary information?

When a subpoena arrives, you must have a “legal hold” protocol that immediately suspends the automated Data Lifecycle Management (DLM) for the specific data sets involved. This prevents the system from deleting evidence, which could lead to severe legal penalties. To avoid a permanent buildup of “dark data,” the protocol must include a clear “release” trigger—once the litigation is officially closed, the legal team must notify IT to lift the hold. This allows the software to resume its normal schedule, purging the now-unnecessary files and bringing storage costs back under control.

Using metadata can help automate the process of moving old data to archives or deleting it. What are the technical hurdles when setting up these automated rules, and how often should the underlying retention schedules be reviewed to ensure they still meet business needs?

The biggest technical hurdle is ensuring the accuracy of your metadata; if a file is mislabeled at creation, the automation might move it to the wrong tier or delete it prematurely. You have to configure the storage system to recognize multiple fields—such as folder, department, and file extension—to make intelligent decisions. Because laws and business goals change so rapidly, I recommend reviewing your retention schedules at least once a year, if not more frequently. These reviews ensure that your automated rules are still aligned with the latest regulatory updates, such as the shifting requirements of the California Privacy Rights Act.

What is your forecast for data retention?

I predict that we are moving toward a future where “automated ethical disposal” becomes the standard, driven by the increasing severity of privacy regulations and the sheer cost of storing unstructured data. We will likely see AI-driven classification tools that can distinguish between a routine email and a vital contract with 99% accuracy, reducing the manual burden on IT teams. As storage volumes continue to explode, organizations will stop viewing data as a permanent asset and start treating it as a liability that must be carefully managed through its entire lifecycle, from the second it is created until its verified destruction.
