If you try to use Wi-Fi you can end up with a corrupted backup every time the backup is ruuning at the same time someone decides to microwave their lunch. If your network is wired and extremely reliable you may never experience problems. Third party NAS drives often use earlier versions of AFP that are not as well-behaved. The second is that the latest versions of AFP handle interrupted network connections relatively reliably. This can be worked round by converting the sparseimage to one with a much larger-than-the-default band size. As the size of the backup set increases the number of these bands increases - there can be tens or hundreds of thousands of them, which exceeds the maximum number of files per directory limit for a typical NAS. The first is that when the backup is to a network volume TM stores its backups in a 'sparseimage', which is a bundle containing an image of an HFS+ file system split into a number of small files known as 'bands'. There are a couple of issues I know about and there may be more.

Finally, on or about December 2014 that model AEBS mysteriously appeared as a supported device in Time Machine's support documentation. Apple never acknowledged either SJ's apparent faux pas or TM's failure to work reliably with those models, and they were never listed as a compatible device until the current production 802.11ac AirPort Extreme was introduced. * note: Apple themselves didn't make things easy for us when upon Time Machine's release, Steve Jobs publicly announced that TM could use a hard disk drive connected to the then-available AirPort Extreme Base Station, when in fact it couldn't. Time Machine has never failed to back up or restore any of my Macs, not once, but I do not use unsupported configurations. Inspect them periodically and keep them functioning, and in all likelihood you'll never need to use them. And if one piece of emergency equipment doesn't function you'd better darn well have another one close at hand. Different people have different needs, but in my mind backups are 'emergency equipment' that simply must function in the dire circumstances in which they are required. That's what makes anything other than the devices specifically enumerated in Apple's TM documentation unsuitable for the purpose. Your eventual recourse might be to get a refund of the NAS's purchase price, but only you can determine the value of your data subject to permanent and irretrievable loss in the event it needs to be recovered, and can't. Either way that leaves you without a backup, and no one will care about that other than you. If you were to do that, they in turn would blame Apple for having done something behind their back, or your network implementation, or you, or anyone and everyone but themselves for having made claims for Time Machine compatibility that cannot be justified. If you were to contact Apple (I have) they would just refer you to the particular NAS device manufacturer since they didn't build it. This unfortunate cycle has repeated since Time Machine was first implemented by Apple nearly a decade ago, and reports such as yours continue to appear on this site with disturbing regularity (see * note below). Upon learning this, the hapless user enters the five stages of grief. Then, when a user needs to restore a file or an entire system from a backup, he finds out that he can't, and blames Time Machine for being unreliable when in fact the TM backup device never conformed to TM's stated requirements to begin with.

When they introduce another macOS upgrade or update non-Apple NAS implementations tend to fail, often silently. During development and evaluation Apple does not test the wide variety of non-Apple NAS devices for compatibility.

The reason is that Apple's Time Machine is proprietary software that uses their proprietary networking protocol, and Apple reserves the right to make frequent changes to both of them.
