Whats with the broken "transfer speed" and "remaining time" estimates in many Acronis products?

Hi,

Can someone (ideally from Acronis) please explain why so many Acronis products, for so long, have had broken backup/restore/validate speed and time remaining indicators?

Firstly, yes, I have trawled the Acronis forms and KB for answers, but only ever find the countless unanswered instances of others asking the same question.

I've been using numerous backup tools from Acronis over the years (B&R SBS 2010 & 11 server, 10 & earlier WS, TIH 2012 and earlier... atleast), to a few different backup media (local disk, USB2/USB3/eSata disk, LAN volume (hosted from windows and Linux servers), & possibly others, and don't particularly recall ever seeing sensible time remaining estimates. Usually a factor of 5+ too long... or speeds varying from way too slow to way too fast (5GB/sec for hours to USB2??? yeah right!!).

I just did an archive verification test with B&R 11.5 WS (see attached screen grabs... and summary below)... and despite perfmon showing steady transfer rate from the USB3 mounted archive, which matched the resulting time of the backup, the time remaining estimates were consistently WAY OFF. This result is also observed by countless others in these forums over the years, and yet it never seems to change?!?!

So whats the deal? Even the MS Windows file copy dialog (pre-win8 - atleast) with its lazy initial estimates tends towards a sensible answer, being vaguely interpretable (esp. with perfmon alongside) once one gets used to it. That in Acronis products seems totally nonsensical! I doubt its a business ploy, or technically challenging, so what else?

Summary of attached results:
Verify1: In the partial screengrab B&R says 46% through after 47mins (100 of 225GB), and it completes after 100mins. All makes sense. Throughout that verify job, the time remaining hovered between 15 & 20 hours, and speed was somehow 0 B/sec (Even if 1B/sec, the ETA would be way more than 15-20hrs). Also, the perfmon charts were also quite conclusive as to the steadiness of datarate of data being pulled from the source drive.
Verify2: Similar results as Verify 1.

Is the speed of 0 B/sec B&W's way of saying "no idea what the speed is, but giving some garbage number to the time remaining code which then reports these bogus estimates"? FWIW, I've seen other variations of this, where the xGB/sec speeds are reported, still with excessive T/R estimates... so the above idea doesn't really hold.

:| Please convincingly explain and even FIX this Acronis!

Stu.
