SYNC - any type - always re-write every file on destination folder
I need to keep multiple folders (total 3TB) identical. For that I have tested multiple Aomei Backupper sync options, all give the same reults: 10 hours sync time.
Source: 5 or 6 folders on a network NAS
Destination: a local USB Disk
I have seen that each time I do a sync (it is not scheduled), my PC copies back 100% of the files from network to my local usb disk, even if they have not been changed.
(i can see the computer task manager writes 100MB/sec and nearly no read operations on local usb disk.)
What am i missing ?
