The next step would be to store a copy of the database offline somewhere else, or even print it out once in a while so there is a physical on paper version somewhere. Out of the gate its replicated/copied to 5 different places. LoTW, QRZ and Club Log also hold complete copies.

Making this stuff last forever, well I have a the local copy that MLDX works from, that syncs to iCloud, and Time Machine also backs it up locally. How I configured all this stuff to work together can be found via my QRZ page (username is my callsign). The same level of functionality should be easily replicated on Windows or Linux with the right logging application between the rig and digi mode apps. CL is good for tracking DXCC progress for example, and those that use the OQRS feature for requesting QSL cards (which I like to collect) is also convenient. I periodically perform the steps with-in QRZ and CL to sync conformations from LoTW so everything matches up nicely. Reason for doing it this way is MLDX knows the mode, frequency and other details when I manually log a voice contact, by manual all I have to do is type in the callsign at the start of the QSO, the rest is automatically captured and logged when the QSO is completed and I click the button to log it. MLDX owns the CAT control of the radio, the digi mode apps interface to MLDX for the rig control.

This way everything is logged in real time, no one is left waiting days/weeks/months for it to confirm in LoTW on my end. MLDX then automatically uploads those to LoTW, QRZ and Club Log. I use MacLoggerDX with WSTJ-X, JTDX, JS8Call, and Fldigi configured to prompt and automatically log contacts.
