Time Machine verification failure (again)

Sorry, when I said perennial, I meant 'out there'. There are threads numerous sites about this problem and they tend to point at the hardware as the cause.

I did a search before posting and didn't see a mention of a utility though I already started using a Time Machine scheduler to try to avoid overwhelming the system at busy times a few years ago in an attempt to get around this problem and since then, Time Machine only backs up once a day.

Yesterday's backup was incredibly slow, 1.4GB took about four hours, then today's seemed to stall at 279MB of 900MB before finally giving the dreaded message.

It was claimed way back when on here that it was a known bug in Lion - three (almost four) full OS X iterations ago. Since I originally encountered the problem back on Lion, on a PowerPC system, it continued through to my current Intel Mac via two entirely new system installations on clean drives and about eight completely replaced Time Machine backups. I might be forgiven for asking why it keeps happening to me (and the other poor victims) whilst others escape.

I can, however, say with absolute certainty, that it never happened before I started using a ReadyNAS for Time Machine backups.
