What is the best way to copy ~2 million files on Windows 2003?
Posted on 2010-08-24
I've recently purchased a duplicate NAS for the sole purpose of mirroring the current one (for redundancy's sake). They each have a 10TB capacity (they are Netgear ReadyNAS Pros). The one with all the files on it has 1.8 million files in 64,357 folders taking up 6.42TB of space. I have tried over the previous two weeks to copy the files over to the new NAS with little success.
First tool i tried was SecondCopy, this crashed a few minutes into the copy, with no error. Second tool was TeraCopy, this too would just fail about 2-3% into the transfer, no error given (just stopped transferring). Third tool i tried was the built in rysnc tool on the readynas, it too failed, with a completely non descriptive error in the log. After that, the fourth tool I've tried is DSynchronize, which seems to work, except about 2 hours into a transfer it starts reporting that files are locked on the source drive, and it too stops in the middle of the job.
Is there a tool that is designed for copying so many files on Windows? I've even tried moving one folder (at the top level) at a time, but even that seems to fail.
