When your mail server goes offline, orders stall, customers wait, and internal work grinds to a halt. That’s why failover and high availability (HA) should be considered with any MDaemon deployment plan. The good news: achieving high availability with MDaemon is far simpler today than it used to be. This guide walks through your options, explains how to choose the right one, and covers the planning and testing that separates a resilient setup from one that only *looks* redundant.

According to [RFC 2142](https://www.ietf.org/rfc/rfc2142.txt), every email domain must have a working postmaster@yourdomain.com address. But beyond compliance, this simple alias plays a critical role in maintaining healthy email communication and managing server-related issues.

You thought you and your employees would all be safely back in the office by now. However, we’re all still adjusting to this new normal of exponentially more remote working – and exponentially more cyberattacks. Every day, hackers [seek to exploit](https://www.securitymagazine.com/articles/93086-the-future-of-hacking-covid-19-shifting-the-way-hackers-work-and-who-they-target) not only fear and insecurity caused by the pandemic, but the security loopholes created as more employees access their email and other work systems from remote devices. According to [one report](https://www.businesswire.com/news/home/20200513005152/en/Bolster’s-Q1-2020-State-Phishing-Online-Fraud), streaming phishing sites saw an 85-percent increase from January to March, with more than 209 malicious websites being created every day.

That's great until the day you need to recover a single message and find yourself wrestling with shutdown states and recovery utilities. MDaemon takes a different approach: your messages, accounts, and settings are stored in flat files. That structure makes it easy to back up and recover your email messages, user accounts, security settings, and any other data stored in MDaemon. No extra Windows components or third-party applications are required, and you won't have to navigate through any confusing dialog boxes to backup & recover your data. Backing up and restoring MDaemon is as easy as drag & drop. All you would need to do is map a drive letter from the MDaemon server to another drive on your network, then drag over the files you want to back up.
