There are many ways to archive emails, the consideration is about accessibility and costs (or your time).
Example: Using Microsoft Outlook for your daily email access, you run out of mailbox space and need to archive the content - Below are these exact scenarios that affect all email users at some point.
Archive in transit
Our service is a MX network with built-in mail archiving. This is paired with your own archives regardless if a single user or a business server.
As the email is archived during transmission, we retain a separate copy of the email your mailbox or server stores regardless of your own archiving method.
As our archive is focused on the last 30 days of email, it is best suited for on-premise mail servers that require time incident/event restore vs full 1st day restore.
Built-in tools or 3rd party software items that create a separate archive of your email, many software tools like "Veeam" backup solutions perform this task. Also archive storage needs to be backed up so malware encryption and human error deleting local archives is not carried over to the archive backup.
Note, gmail and other email services are subjected to the same security and user archive issues, this can be external security events or staffing issues.
Without archiving its very hard to un-do any incident.
The best solution?
Well the best solution is the one with multiple copies of your data using different archive methods to remove a single point of archive failure, so combining our MX delivery archive with your archiving processes allows your business to be sure you can compare results and restore a copy. The primary benefit of our delivery archive is it does not require software to be installed prior to restore, these are sent to a email address you nominate.
