Time Machine verification failure (again)
I know this has been discussed before but it seems like a perennial question. The problem occurred with my ReadyNAS Duo every few months and this is the second time it has happened with my RN102 ...
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.

I wasn't doubting you. Just saying its been a few years since anyone has posted this issue here, and I don't think any of the other posts were for OS6 systems.
It might be on Netgear's list anyway if there are support requests. You probably should report a bug at support.netgear.com (w/o opening a case if you want to avoid a charge).
Thanks.
My Mac is still busy creating a new backup so I am in the claustrophobic iPad environment. I will follow up your suggestion when I have a real keyboard in front of me.
After leaving my Mac unattended for almost two days whilst it created a new backup, I checked it today and it said it was complete. When the time came for the first scheduled backup, I got the verification failure message again.
This is where I start to feel exasperated. What am I supposed to do? If I post the problem on Apple's discussion site (which I have done in the past), one of two or three people who seem to have answers for everything will tell me it's a problem with your NAS. Here I am told that it is not a ReadyNAS problem per se.
I am over a barrel and I doubt I will get any practical support from anywhere because everybody wants to slope shoulder the issue onto somebody else.
I will just have to erase my RN102 and start again - the third time I have had to do so in nine months.
I do understand the frustration.
I don't work for Netgear so I can't commit them to anything. You could try a support case, Or perhaps PM some netgear folks here, and ask what else you could do.
I appreciate that you aren't responsible and I have submitted a support request.
I was searching again for answers and found a response from a Level 10 (175k+ points) support person on the Apple discussion site which typifies what I said earlier:
https://discussions.apple.com/thread/3795735
'Using a third-party NAS as a Time Machine backup destination is unsupported by Apple and should be considered risky. Your only recourse if you have problems is the NAS vendor, who will blame the problem on Apple.'
I have found Terminal commands which supposedly fix the problem but to be honest, I feel out of my depth at that point.
