Expected incremental backup performance on Mid-2015 MacBook Pro
With those sorts of times it would appear that Acronis does a brute-force scan of the whole filesystem comparing each file.

But since 10.7 (Lion) macOS provides a mechanism called FSEvents that allows an app to be notified about changes so it can do its job in a much more efficient way. Time Machine uses FSEvents.

So, to answer your question: Your times are about right for software that is doing the scan inefficiently. As a Time Machine user I see far shorter times for much more data (600GB on SSD to external 1TB HDD over Thunderbolt) using my 3GHz i7 MacBook Pro (Retina, 13-inch, Early 2013) running High Sierra and APFS.

My recommendation is that you change software to one that is more modern in its approach.

PS: Time Machine would backup your old Mac and restore to a new Mac, though it does it using its usual loose files approach rather than a single monolithic image. It would also only backup changes to your Parallels VM – no such luck for a VMware Fusion user like myself.
