I still haven't found something that seems to work well, but I haven't checked all the recommendations yet. I'm definitely going to post a summary but it's probably a month away at least as I have two weeks of computer-less vacation coming up. The big problem is that these large file synchronizations seem to be revealing stability issues in some systems that were otherwise hidden.
I'm encountering a lot of stability issues when trying to do multi-Terabyte copies or synchronizations. Several systems that are otherwise rock solid, hard freeze or BSOD when confronted with copying or synchronizing 4-5 Terabytes of data.
All these systems pass Memtest86+ for days without errors. They also have no problem with Prime95, and there are no errors with a CHKDSK /r. I'm beginning to think it's a Windows issue --that Windows just can't handle that much data movement sustained over a day or two. Haven't tried Linux yet though. In terms of hardware, I'm down to replacing motherboards or even the HDDs on a couple boxes --they're the only possible faults. I've literally swapped out SSDs, PSUs, SATA cables, and video cards on a couple systems now.
These issues seem to persist whether it's over the LAN or if I physically move disks between computers
. The only consistent thing seems to be the volume of data.
Anyone else ever try to copy 4-5 TB of data between systems? Did it work?
