Why Data Storage Location Matters
Not all data is created equal, and not all of it should end up in the same place. Working data that an employee edits on an ongoing basis is governed by different rules than archived client contracts or project backups. The problem begins when a company has no policy in this regard - and every employee stores data wherever it is convenient for them.
The consequences are predictable: client data on private cloud accounts, invoices only on a local drive without backup, contracts scattered across mailboxes. When something goes wrong - a breakdown, an employee leaving, a security incident - the company discovers it does not know where its data is.
What to Keep Locally
A local drive only makes sense for temporary data - working files that an employee is actively editing and that will soon be moved to shared resources. Nothing of importance to the company should end its life cycle solely on a local drive.
The reason is simple: a local drive is not covered by central backup, is not accessible to other employees, and disappears along with the computer if it fails or is stolen. Data on a local drive is outside IT control - the company does not know what is there, cannot secure it, or recover it.
What to Keep in the Corporate Cloud
The corporate cloud - whether Microsoft 365, Google Workspace, or a file server - should be the default location for all documents that matter to the organization. Contracts, invoices, projects, correspondence with clients - everything the company wants to keep and that more than one person might need access to.
The corporate cloud provides central control over data: it is clear who has access, access can be revoked when an employee leaves, the data is backed up, and it is accessible from any device. This is also the only place that offers a real opportunity to meet GDPR requirements - it is difficult to demonstrate control over personal data when it is scattered across employees' private accounts.
What to Avoid
Private cloud accounts represent the greatest risk to data hygiene. An employee who sends a file via a private Dropbox account or saves a contract on a private Google Drive is moving data outside the company's control - even if they do so in good faith because it was more convenient. This is one of the manifestations of shadow IT - uncontrolled solutions that a company usually discovers when it is already too late.
USB flash drives are a separate risk category. They are easy to lose, easy to steal, they are not encrypted, and they do not have any access history. Company data on a USB flash drive is data that the company has de facto left to chance.
Using an email inbox as a document archive is another bad habit. Searching for a contract from two years ago in the chaos of an inbox is a waste of time - and when an employee leaves, their mailbox usually disappears with them.
How to Implement a Data Storage Policy
A policy on paper alone is not enough. Employees will return to old habits if corporate tools are less convenient than private alternatives. The key is to provide solutions that are simpler to use than workarounds - and configure them so that the default behavior of the system routes data to the correct location.
The IT department plays a central role here - both in selecting tools and in enforcing rules through appropriate permissions and device configuration. If a company does not have its own resources in this area, this role can be assumed by external IT support. It is also worth taking a broader look at employees' daily computer habits - data policy is just one piece of a larger puzzle.
How it Looks at Helpwise
The data storage policy is one of the areas that we discuss with every new client during onboarding as part of our IT support for companies. We help define where different categories of data should go, configure permissions, and ensure that backups cover all locations where company data is actually stored.
