Frequently Asked Questions

Why do you need an email archiving solution and what does email archiving have to do with legal and regulatory compliance? Find answers to these and other questions here.

What Is Email Archiving?

Emails are not only an important means of communication, they’re also a comprehensive and valuable information resource for any company. An email archiving solution retains emails and their attachments in a central archive, ensuring permanent availability and restorability. Email archiving is regarded as part of your IT-strategy to ensure business continuity and data governance.

How Does Email Archiving Work?

An email archive serves as a supplement to an existing email system. The administrator defines which emails are to be moved to the archive and at what time, and whether the emails, once archived, should be deleted from the mailboxes on the email server. Ideally, the archive will be able to manage very large volumes of data efficiently.

What Does Email Archiving Have to Do with Regulatory Compliance?

There are legal and regulatory requirements to properly manage and retain business email in most countries and industries. These requirements need to be considered as well as data privacy regulations like the EU’s GDPR. A professional email archiving solution should enable your business by offering compliance features to retain emails for many years in a form that is complete, faithful to the original, tamper-proof, and permanently available.

What is the Difference Between Archiving Email and a Backup?

The primary objective of any email archiving solution is to ensure that email data remain available and recoverable over time. In contrast, the purpose of backups is to store data regularly over short to medium time frames, thus providing a snapshot of the data in question. It caters primarily to disaster recovery scenarios.
