Cleanmail Mail Archive

What’s the value of your mail data? The Mail Archive is the insurance you need to secure that value.

Do you have business or legal needs to archive your mails? How do you access mails of an employee who left a few years ago? How do you access your mails if you have issues with your cloud-based mail provider? The Cleanmail Mail Archive provides you with the long-term archiving of your messages in an encrypted immutable storage, compliant with legal, regulatory and audit requirements. It gives you an astonishingly fast search engine for all your mails—including text in attachments.

For invoicing purposes, the overall data volume used by the customer is considered (the „volume of the archive“). This volume is calculated after deduplication, compression and encryption, which typically reduces the overall volume by 40% to 60% compared to the raw data. On average we calculate with a volume of 1 Gbyte per user and archive retention year. This number may fluctuate depending on the type of users.

Additional Archive Accesses

Optionally individual archive accesses for some or for all users can be created. This provides access to the users’ own mail archive (“basic users” with all search and retrieval functions. “Privileged users” can be configured to access data of multiple users. There is no additional charge for the user accesses, only the archive volume according to the above table is charged.

Migration and Import of existing data

If you already have an e-mail archive, or you have Gbytes of e-mail data in your Outlook PST-files, we can import them for you into the Cleanmail E-Mail Archive. Your data will be indexed and made available in the regular full-text search. We charge CHF 25.- per mailbox. This service can either be ordered with the initial creation of the service, or can be ordered at any later point in time.

Please note that such imports can only be fully auditable if the full chain can be verified for completeness and accuracy. Usually this is not possible with PST files, but it may be available if importing from an earlier archive system.
