Impossible Backup, ~440GB, ~2.5M files, Long Paths (>260 Characters).

I am losing my mind with Acronis over these past few months. I have recommended it extensively to a client for its robust imaging capacity and reliable and easily controlled scheduling, but out of 4 major tasks that have been required of it in the past 6 months, it is currently 0/4. I have had to purchase alternative software in some cases and to use freeware alternatives in others. I am a very frustrated admin here.

I have a large data set, as described in the title ~440GB in size, about 2.5 million files, with many directories which go beyond the 260 character limit. This data is intelligence data of exceptional importance. My client has just finally upgraded their branch office Windows Server 2003 R2 32 bit box to a new Server 2012 box. The old server has a 4TB data array on which these critical files are stored, and a 300GB operating system array, both formatted NTFS. The new server has a single array of 6TB split into a 300GB NTFS operating system array and a 5TB ReFS data array. The backup drive is a WD 3TB USB 3.0 Drive.

I have a backup the data made from the old system. It completes successfully, but I am unable to verify it as Acronis crashes with a C++ error. After several attempts to verify the data with the same error, I gave up and moved to the new system, figuring that I would find a way to verify it later. Now, when I attempt to restore the data I get an error at 6%:

I have no doubt in my mind, that if I cannot get Acronis to work with this data, I will be switching products to Paragon, whose Drive Copy resolved the last situation where I could not clone a 120GB SSD that was failing or a 3TB GPT disk on the same system.
