FASTEST WAY TO COPY FILES BETWEEN TWO SYNOLOGY NAS DEVICES
Windows is slow…takes weeks to copy 15TB between two devices if you use explorer. Here is how you copy the files in hours instead of weeks.
On your Windows 11 computer
Open Explorer
Navigate to Synology 1
Map a Drive from your Windows 11 pc to the Synology Share
ex. Drive X will be \\Synology1\Share
Now do the same for Synology 2 and the share you want to map.
ex. Drive Y will be \\Synology2\Share
On your Windows 11 pc, now open PowerShell (not as Administrator, just open PowerShell)
Type:
robocopy ‘X:\FolderYouAreCopyingFrom’ ‘Y:\FolderYouAreCopyingTo’ /S /E /MT:32 /NFL /NDL /NJH /NJS
example: robocopy ‘X:\SourceCode\Documents’ ‘Y:\NewSourceCodeRepo\Documents’ /S /E /MT:32 /NFL /NDL /NJH /NJS /V
You will copy thousands of files per second over a 1GbE network
