Aomei is a younger company, or acts like one, without as lengthy a background as better established alternatives. Its software seems younger too, without the more involved features found with bigger brands, and then there's stuff like Aomie Not putting system files where you'd expect seasoned pros to put them. There's no win8/8.1 touchscreen GUI -- not a huge problem, but a strong hint that they've not really done much in the area of full win8.1 compatibility. Their GUI is simpler -- which many folks like -- but like many Chinese apps it's not resizable, meaning the coding tools they used were not the latest Windows fare by any means. Compared to established brands like Acronis, Symantec, Paragon, EaseUS etc., Aomei software hasn't been installed on as many machines over as many years, so the odds are better that there might be undetected bugs or compatibility issues
Those are potential caveats I just listed. If it works for you, and I mean restoring backups as well as creating them, there's little reason not to go for it if you want. It's not rocket science to copy raw data from your HDD, storing that data in whatever sort of archive files. Nor is it rocket science to copy that raw data from those archives & put it back on a HDD. If you're happy with Acronis or Easesu or Paragon or Symantec etc. right now I don't see any reason to bother with Backupper -- the same can be said IMHO with Aomei's other products. If you've got an old version of Acronis or Symantec & don't want to pay to get current, maybe Aomie's an OK alternative, but if you run EaseUS or Paragon, the free versions of EaseUS & Paragon give you the same stuff & might work well enough with what you've already got, e.g. backups & rescue discs.
As far as installation goes, AOMEI Backupper Pro 2.0 does have a smaller footprint in Windows than something like Acronis -- it's roughly the same as EaseUS & Paragon. And you **might** get away running it semi-portably by copying the program's folder to something like a USB stick, though you won't have any functions requiring the drivers, might have to register the app each time, & will likely get a new folder in All Users or All Users Application Data [depending on Windows version] -- needless to say you're on your own with this sort of thing so test, a Lot.
Aomei has some fan boys. When one of their apps is on GOTD or similar, or when you read user reports &/or reviews, please take what fanboys say with a grain or two of salt. The 1st comment Friday was a good example --the person said that they're a software engineer... if they are, judging from their post, odds are they're a pretty poor one. And Giovanni is Giovanni -- trying to be helpful, always enthusiastic, perhaps not as worried about details or depth. Maybe Aomei promotes these sorts of posts, maybe not, but do please take them with a grain of salt. Inaccurate posts about Backupper Pro &/or backing up in general are what prompts me to write this.
Now, I've never had a problem using Acronis or EaseUS or Paragon -- I haven't had a problem with Aomei either but I haven't used it enough for that to mean anything. When win8.1 came out I tested Paragon's Backup & Restore with it, & found a problem. Since Paragon had not yet released their versions designed for win8.1, I couldn't fault them -- I bought a copy of Acronis to tide me over until the new versions were released. That's the important thing I want to note -- I tested it before I trusted it. When you absolutely need it is not the time to find out whatever software doesn't work for you.
I Know this will likely sound terribly cruel, but when I read comments that backup software brand X didn't work for me & I lost everything, my reaction is always if that's true [yes posts are not always honest], then that person has themselves to blame. If it's worth backing up, it's worth testing, it's worth a trial run to make sure everything works. Sometimes folks think they understand how software or a particular job works, then find out they're wrong when they try it -- you don't want to find that out when *Everything* depends on you restoring a backup. When it's your stuff -- it's your responsibility. If you make the decision not to test, or not to backup, accept the fact you made that decision if [heaven forbid] everything goes wrong. If you make the decision to protect & preserve your digital stuff, think redundancy, with as many ways out of trouble as you can manage.
One way to lessen the risks of testing on a live system is to backup your system using 3 or more backup apps, create the necessary rescue discs, & restore a backup. If one doesn't work, then another should, so you're not out in the cold. Print out or write down any directions beforehand. Testing with a VM [Virtual Machine] or on a secondary system makes sure you understand how the software works, but you won't know until you try it if somehow it's incompatible with your main PC/laptop. If you can, that's one advantage of dual booting -- if you're in XP or win7, backing up & restoring a win8.1 partition, if things go wrong with the backup you can go online & investigate why for example.
If you're worried about bloat from backup software you might uninstall, use a virtualization app like Time Freeze, installing the software, creating a backup & rescue disc, then restoring your system to the way it was before you installed the software. Then do it again with another brand. If you restore a backup of your system disk/partition, & you like the way everything worked, that software will be installed -- if it didn't work or if you didn't like it, try the next choice & same thing, once you restore the backup that software's installed.
Another way to test backup & restore software, but with less risk, is if you use another drive [internal, or external using eSATA] or another partition on your single hard drive. I have a eSATA houseing that's very easy to swap drives in/out. I can restore a backup [including the 1st disk track so it boots] to a drive in that eSATA housing, then select it during boot by pressing a hot key when the PC is starting up. An internal partition or drive works the same way -- my eSATA housing is just easier since all my internal drives have stuff on them. Unless it's modified Windows won't boot on a USB drive.
If you use an external drive to store your backups, you should test things out the same way. One unknown is does the connection to the external drive work as well when you're using a boot disc or USB stick as it does in Windows? Hardware can use special Windows drivers for that stuff, so it may not even work outside of Windows. Often another unknown is how your external drive & its interface [how it connects to your PC/laptop] handles a sustained, high data rate transfer. If you backup to that drive the software may not push things to their limit the same way as if you copied that data to & from the drive. You might get an idea of how well it works by copying backup archives to it from an internal hard drive, checking their integrity, copying the files back, & again checking integrity. I do that a few times if/when I get a new drive housing or dock. I've had some fail. If you can't restore a backup because of something like that, the backup is useless.
Bear in mind that Lots of hard drive models have a pretty shocking failure rate -- do what you can to put the odds a bit more in your favor, e.g. maybe paying a little more for a drive with better user reviews, or maybe taking the time to burn your backup archives to disc as well. And try to keep external & internal drives cooler -- the lack of adequate cooling may contribute to or even cause drive failure.
