We live surrounded by photos, videos, documents and online accounts They tell the story of who we are, what we do, and what we've built. However, many of these essential memories and files are stored on degrading media, on services over which we have no real control, or protected with weak passwords. The result is that, without realizing it, our digital heritage is more at risk than it seems.
Think for a moment about a CD with family photos, an old hard drive full of work projects or that folder in the cloud with key legal documents. Now imagine that in a few years you can no longer open any of it because the storage has failed, the format has become obsolete, or someone has encrypted all your data using a ransomware attackIt's not science fiction: it's what happens every day to people and companies that don't manage their digital assets with a clear strategy.
What are digital assets today: much more than photos and documents
When we talk about digital assets, we're not just referring to files saved on a computerThis includes photographs, videos, PDF documents, databases, emails, customer records, digital artwork, cryptocurrencies, social media accounts, web domains, and any other valuable information stored in digital format.
In the business world, these assets form part of the operational and legal core of the company: contracts, invoices, customer files, internal documentation, communications with suppliers, etc. A total or partial loss of this data can paralyze the activity, generate penalties for non-compliance with the GDPR and have a huge economic impact.
On a personal level, the value is different but equally important: Unforgettable memories, creative projectsMedical or legal documents, access codes to online platforms, and increasingly, cryptocurrency wallets or other forms of digital investment. All of this constitutes an asset that should be protected just as we would protect a home or a bank account.
Digital obsolescence: the silent enemy of your photos, videos, and documents
One of the biggest dangers to your digital assets is the technological obsolescenceNot only do hard drives fail, but file formats and the programs needed to open them also become outdated. What seems standard and compatible today could be a major headache in 15 or 20 years.
This problem is clearly seen in formats such as JPEG for photos or certain video codecsAlthough they are perfect for everyday use and for quickly sharing files, they are not intended for very long-term preservation: they use lossy compression, depend on specific programs, and do not always store complete metadata.
The key is to adopt a mindset of digital archivistStop thinking only about “saving files” and start thinking about “building a legacy.” This means considering whether someone, 30 years from now, will be able not only to open a document, but also to understand what it is, who created it, when, and in what context.
That is why leading institutions have standardized the use of robust preservation formats to ensure the future readability of the information, and it's a good idea to copy these practices in our personal and professional lives.
Future-proof formats: PDF/A, TIFF and others
The first serious step to protecting your digital assets is choosing the right one preservation file formatHere it is important to differentiate between access formats (lightweight, for daily use) and preservation formats (stable and complete, for long-term archiving).
In text documents, reports, and files, the reference standard is the PDF / AA variant of PDF designed specifically for long-term archiving. This file type integrates fonts, color profiles, and metadata within the document itself, so that the original appearance is preserved in the future even if programs and operating systems change.
In Spain, the use of PDF/A is mandatory in public administration For electronic archiving, this is precisely because it offers stability and guarantees that the document will look the same decades from now. For individual users or private companies, adopting it for contracts, deeds, important reports, or legal documentation is a very wise decision.
For images that we want to preserve in the highest quality, the format is king. Uncompressed TIFFIt is the gold standard in archives, museums and conservation centers (such as large Spanish museums) because it stores image information without loss and with great color depth, allowing future restorations, reprints or adaptations without degrading the original.
To sum it up: for each truly important photo or document, it's advisable to create one master copy in preservation format (PDF/A for text, uncompressed TIFF for image). This master is treated as the “digital negative”: it is not manipulated, and any edits or variations are generated from it.
In comparison, formats such as JPEG They have less practical durability as archiving media, not so much because they'll "break," but because their reliance on codecs and lossy compression makes them less suitable as a permanent backup. They're great for reference copies, websites, or sending files, but not for securing your memories for 50 years.
Where to store your digital assets: cloud, disks and the 3-2-1 rule
Once you're clear on what format to save your files in, it's time to decide. where to store themThe answer here is not "only in the cloud" or "only on hard drives," but a strategic combination of both worlds.
Cloud services like Google Drive, Dropbox, or iCloud are incredibly convenient, but depending 100% on a single provider is a avoidable riskThey can change policies, raise prices, suffer security breaches, or, in the worst-case scenario, cease operations altogether. Furthermore, many providers host their servers outside the EU, which raises GDPR compliance issues in business environments.
On the other hand, relying solely on local hard drives, NAS or SSDs It's also insufficient: theft, fire, floods, or a simple power outage can leave you with nothing in a matter of seconds. The professional solution, which you can implement at home or in your business, is the 3-2-1 backup strategy.
- Three copies of your important data.
- Two different types of support (for example, the computer's internal disk and external hard drive/SSD).
- A copy outside the home or office (off-site), ideally in the cloud or another secure physical location.
The off-site copy is what saves you in case of local disasterThis is where the cloud comes into play, but with discernment: for particularly sensitive data, it makes sense to choose European providers that fully comply with the GDPR and offer robust encryption and transparent privacy policies.
Applying the 3-2-1 rule means that your digital assets are distributed among fast local storage (for daily work) and secure remote storage (for serious emergencies). It's not about choosing "cloud or hard drive," but about combining them intelligently.
Organization, file names, and metadata: let your documents speak for you
It's not very useful to save and back up your files if later they are lost or stolen. impossible to locate anythingOrganization is the key to transforming a lot of data into a useful file, both for you and for whoever has to manage it in a few years.
The typical filename of the type “IMG_2458.JPG"It says nothing about the content. If you accumulate thousands of photos like that, in ten years you'll have to open them one by one to figure out what each thing is. It's much better to build a logical and predictable naming system that includes the date, event, and a brief description."
A practical structure might look something like this: YYYY-MM-DD_Event_Sequential-Description.extFor example: “2023-08-15_Vacaciones-Mallorca_Playa-Es-Trenc-001.tif”. Without opening it, you already know when it was taken, in what context, and more or less what appears in it.
The second major pillar is the MetadataThat is, the information embedded within the file itself. Standards such as IPTC or XMP allow you to add fields like author, description, keywords, location, copyright, or technical information. Many photography and document management programs (Bridge, Lightroom, professional managers) allow you to edit these fields in bulk.
When you complete metadata you are building a context capsule that accompanies the file wherever it goes. Even if you change software, this data usually travels with the image or document, making its cataloging, searching, and future understanding much easier.
Physical media: when to migrate old CDs, DVDs and hard drives

Choosing the right formats and having multiple copies doesn't eliminate the problem that the Physical media degradeRecordable CDs and DVDs suffer from what is called "disc rot": the reflective layer oxidizes and the reader is no longer able to interpret the data, sometimes without prior warning.
Mechanical hard drives (HDDs) have moving parts, are sensitive to shocks, vibrations, and magnetic fields, and can gradually fail over time. Solid-state drives (SSDs) eliminate moving parts, but have a limited number of write cycles and can lose data if left without power for many years.
This leads us to the concept of support life cycleNo storage medium is eternal, and digital preservation requires a proactive approach: periodic migrations must be planned before failures occur.
A reasonable practice is to periodically review the status of each type of media and schedule migrations at specific intervals. For example, check CDs and DVDs every two years and migrate them to new media around five years; monitor hard drives using SMART tools at least once a year and replace them between 3 and 5 years; check SSDs periodically and rotate them to new devices between 5 and 7 years.
During any migration, it is essential to verify the file integrityTools that generate checksums (digital fingerprints of the data) using algorithms such as SHA-256 allow you to compare the original with the copy and confirm that there has been no bit corruption in the process.
Cyberattacks, malware, and document management in companies
Beyond the physical deterioration of storage media, the other major threat to the protection of digital assets is the cyberattacksAs companies digitize their documentation and migrate processes to the cloud, the opportunities for attackers to attempt to steal, encrypt, or destroy sensitive information increase.
Modern document management systems combine automation, remote access, and Security controlsHowever, they are not immune if not configured correctly. Security in this area is usually structured around three pillars: software security (encryption, frequent backups, GDPR compliance), authentication (only authorized users can log in), and authorization (each user only sees and modifies what they actually need).
In practice, many companies have suffered incidents with consequences in the millions: service interruptions of more than five hoursLoss of customer trust, penalties for data breaches, and exorbitant recovery costs. A single well-executed attack can cripple an entire organization's operations for days.
Among the most common types of attack are the Phishing (fake emails that impersonate banks or other entities to steal credentials or card data), the spyware (spyware that collects browsing habits and personal data), adware (programs that display intrusive advertising and can record keystrokes), and, increasingly, ransomware.
How to strengthen cybersecurity in document management
To minimize these risks, organizations need more than just a good antivirus. They need a comprehensive approach that combines technology, processes and trainingA highly recommended first step is to commission a security audit or ethical hacking tests to identify vulnerabilities in systems, networks, and applications.
Furthermore, training the team is essential: a large proportion of attacks come in through user errorsSuch actions include clicking on suspicious links, downloading malicious attachments, or reusing the same password everywhere. Regular awareness programs and clear incident reporting procedures can make all the difference.
Another key point is to define a internal protocol This includes backup planning, access segmentation, permissions review, and incident response. It's not just about prevention, but about knowing what to do when something goes wrong to minimize the impact.
Many companies are choosing to hire ethical hackers or external cybersecurity specialists to simulate real attacks, detect weak points and help strengthen infrastructures, from firewalls to document management servers.
In parallel, professional document management solutions that incorporate data encryption, automated backups, robust authentication and GDPR compliance can greatly facilitate keeping files organized and protected, provided they are accompanied by good practices and continuous monitoring.
Password security and the great human failing
A recurring flaw that ruins many protection strategies is the poor password managementIt's not very useful to have robust formats, 3-2-1 backups, and secure software if a cybercriminal manages to gain access with a password reused on twenty different sites.
A large proportion of non-technical employees and many home users continue to use the same password for email, cloud storage, social media, and internal company tools. When one of these platforms suffers a breach and passwords are exposed, attackers automatically try those passwords on other services, starting with the primary email and cloud storage.
The answer lies in using a password managerA program or service that stores all your passwords in an encrypted vault and generates long, unique passwords for each website or application. This way, you only need to remember one strong master password, instead of dozens of weak and reused combinations.
The second essential pillar is to activate the two-factor authentication (2FA) on all important accounts, especially your primary email and the platforms where you store backups. With 2FA, even if someone steals your password, they will still need an additional code generated on your mobile phone or another device to log in.
This extra layer of security is one of the most effective and simple measures you can implement to protect your digital assets against brute-force attacks, data breaches, and more or less sophisticated phishing campaigns.
Digital financial assets: cryptocurrencies, custody, and private keys
Digital assets are not just memories and documents: they also include cryptocurrencies and tokens which, in many cases, represent very large sums of money. This type of asset is based on blockchain technology, which is decentralized by design and does not depend on banks or governments to move funds.
In this environment, access to money is not defined by a bank account, but by... possession of a private key and a seed phrase or recovery phrase (usually 12, 18 or 24 random words) that acts as a “master key” to rebuild the wallet.
If you lose that seed phrase or private key, nobody can reset your accessBecause there is no "central bank" to handle complaints. Similarly, if someone steals that data, they can move your funds without any easy way to recover them.
There are two main approaches to storing these assets: custody by third parties (a bank, a regulated exchange or another reliable entity holds your private key) and self-custody (you manage your keys and wallet yourself, either with a hardware or software wallet).
Third-party custody facilitates daily use and provides the convenience of being able to regain access If you lose your account password, it forces you to trust that the company operates securely, is regulated, and complies with the financial regulations of the country in which it operates.
Self-custody, on the other hand, gives you total control, but also makes you fully responsible. In hardware wallets and physical copying methods, it is recommended to split the seed phrase into several parts stored in different locationsso that it can be rebuilt if a location is compromised, but a thief cannot access your funds with just one piece.
In software wallets, you should never store passwords or seed phrases in plain text on internet-connected devices. Ideally, keep them on secure physical media and, if possible, combine this with encrypted vaults and well-protected redundant copies.
Digital legacy and inheritance: what happens to your accounts and files when you die
Another aspect that is often overlooked is what happens to your online accounts, cloud files, and digital assets when you're gone. Without a plan, your heirs may face a legal and technical barrier preventing them from accessing important information or properly managing your profiles and portfolios.
In Spain, data protection regulations have incorporated the concept of digital testamentThis allows you to designate in a will a person (digital heir or executor) responsible for managing, closing, transferring, or preserving your digital assets according to your instructions.
For this figure to be truly useful, it is advisable to prepare a inventory of relevant digital assetsEmail accounts, cloud storage services, domains, social media profiles, cryptocurrency wallets, investment platforms, etc. It's not necessary to detail passwords in the will, but you must indicate their existence and how they can be legally accessed.
The most delicate part is secure access to the keys. One option is to use a password manager that includes a password protection function. legacy contact or emergency accessso that a designated person can enter your vault under certain verified circumstances (for example, after a prolonged period of inactivity or upon proof of death).
Incorporating these instructions into your will, with appropriate legal advice, is a very concrete way to ensure that everything you have built and accumulated in the digital world is not locked or lost when your family members need to manage it.
Digital art and works: what to give the collector so that the piece survives
In the field of digital art, asset protection takes on a special dimension: we are not only talking about preserve memoriesbut to ensure the market value of photographs, videos, generative pieces and other works created and sold in digital format.
When an artist sells a digital work, they are actually selling a file and the promise that that file will be displayable and legible in the futureTo achieve this, leading galleries have developed delivery protocols that go beyond simply sending a file by email.
It is usual to prepare a “digital work dossier” that includes at least: a master file in preservation format (e.g., uncompressed TIFF for still images or a lossless video format), a lighter viewing copy (high-quality JPEG, optimized MP4, etc.), a certificate of authenticity (often in PDF/A, digitally signed), and a document with technical instructions for preservation and display.
Some galleries and contemporary art fairs include clauses in their contracts regarding future migration of formatsso that the artist or a designated professional undertakes to update the work to new standards from time to time to ensure its compatibility with the technology of the moment.
This professional approach not only protects the integrity of the work, but also gives confidence to the collector, who receives a coherent package with documentation, suitable physical support (such as a professional-grade SSD) and mechanisms to verify the integrity of the files, for example through checksums.
3D digitization: scanning versus photogrammetry for preserving physical objects
Digital preservation also applies to physical objects: sculptures, archaeological pieces, architectural elements, etc. Creating a 3D digital twin It allows us to study them, virtually restore them, and preserve their form even if the original suffers damage over time.
The two most commonly used technologies are 3D scan and photogrammetry. Structured light or laser 3D scanning projects light patterns onto the object and measures the deformation to reconstruct its geometry with great precision, often at the submillimeter level. It is ideal for small to medium-sized parts where geometric accuracy is critical.
Photogrammetry, on the other hand, is based on taking many photographs from different angles and using specialized software to generate a 3D model from them. It is a more accessible, economical technique and especially good for capture realistic textures and colors, which makes it very popular in archaeology and large-scale heritage conservation.
The choice between one or the other depends on the type of object, the budget, and the project's objective. Shiny or transparent objects, for example, are often problematic for photogrammetry and work better with laser scanning; on the other hand, projects with limited resources or large excavation areas tend to favor photogrammetry.
In both cases, it is crucial not only to generate the model, but save the 3D files (whether PLY, OBJ, glTF or other standard formats) following the same good preservation practices: 3-2-1 copies, full metadata, non-proprietary formats where possible and migration planning as standards evolve.
This entire set of strategies—choosing robust formats, combining local and cloud storage with the 3-2-1 rule, organizing strategically, migrating on time, strengthening cybersecurity, managing legacy systems, and taking care of both born-digital and digitized assets—transforms what could be a chaotic mess of scattered files into a solid and lasting digital heritage that withstands technical failures, attacks and the inevitable passage of time.
