what does a "one year license" mean? it stops working after 1 year?

I'm going to stick with the last persistent AOMEI backupper Pro giveaway license which for me was 3.5... I did not get around to installing the 4.0.2 which I believe was also a persistent Pro license. This being only a 1 year license and the price is the same quoted on persistent license giveaways so no, not a good deal. On the other hand IF this 1 year license means 1 year of updates but the program remains Pro licensed for as long as the installation lasts... then I will reconsider.

The $39.95 price quoted seems to match the persistent no "major" version updates license from their site which with this company they call a 4.6 to 4.7 a "major" version update NOT from 4.x to 5.x so logically a minor version update must be between 4.6.2 and 4.6.9 I wonder what they call a 4.x.x to 5.x.x version update a super version update?

Also note the CURRENT AOMEI Backupper Pro on their website is 4.6.3 so would be useful to have an AOMEI representative clarify the meaning of the giveaway license duration exactly AND tell the visitors here if they can install the current 4.6.3 version with the giveaway license?

What happens after one year?

No matter how 'clean' you keep your PC, get this, burn a boot CD, create an image of at least your HD boot partition about once a month, and you're good to go, SAVES YOUR BACON.

Excellent software, but a 1 year licence is just pants. Can understand Aomei not giving away a premium product, but they could have just 'nobbled' it slightly, instead of giving away a trial of their software. Before, when a new version was released, software companies would give away their previous version, in a hope users would upgrade. Nowadays, its just 12 or 6 month trials. This means you're going to back up your system, then when you really need that backup, you won't be able to use it, as the software would have expired. Gah.
Aomei has been around a while and do regularly update their software. A similar program was given away recently, but this application has more 'miles' under its belt, and I'd trust it more to backup my system. I've used the previous versions of this with no issues.
There is a free edition of this software, and its a shame Aomei have sneakily taken more and more features out of the free edition and moved them to the professional. For most users though, the free one 'is good enough' - images your system and lets you restore it back again.
If you're in a corporate environment, the PXE boot is very useful - boot Aomei from a computer simply by rebooting it and setting the necessary boot option (boot from the network). This means you can easily back up several machines at once, rather than using several USB pens or CD ROMs. Recovering onto different hardware is also an excellent feature. Windows 10 complains a bit more about this, but this might be resolved in the newer versions. Think I was using 4.02 or some such. Again, more useful in the corporate world.
I've mentioned here before the benefits of an image backup over a directory backup, and doing these image backups regularly. Aomei Backupper is good for this, as it supports incremental and differential image backups.
Aomei backupper has a great user interface, and can even be run from the command line. This makes it easy to run from a batch file.
If you have a laptop, its especially important to have an image backup, as they're harder to get back up and running in the event of a system rebuild - network cards tend to be more 'specific', so finding all the right drivers again from a 'bare metal' rebuild can be a lengthy process. if you've an image from a known working ppoint in time, it can make a recovery take 30 minutes - again, fabulous in the corporate world when Jeremy in Accounts installs 'that new browser he's heard about' and now 'his PC won't start and I've tried to fix it but made matters worse. I'm due in a meeting in ten minutes - can you sort it??'. etc.
