Anybody know a fast way to copy about seven years worth of AutoCAD .dwg files from one external drive to another? It's about a four-employee business. They're stored in one Seagate drive now. I'd like to store them in a second as well as a backup.
If you can take it off line you can use a usb duplicator or pull it out of the case and copy it. The Seagate's cases that I've taken apart were pretty much destroyed.
the fastest way would be plugging both in and running the dd command because you can adjust the block size to discover which provides the highest throughput for your cpu/available memory/caching size and speed for each drive/current cpu cores load/phase of the moon/...
it would take several attempts to experiment the most efficient bs; i would just plug them both in and drag-and-drop.
actually i take that back... dd would copy the whole drive (empty space included) which would waste time.
I highly recommend this for large copy operations. It is WAY better than the copy handler in Windows. Just set it and forget it. If there are any problems along the way you will know about it. It keeps the results of the entire operation in a log and you can go back and check them out. I've been using it for years on all of my systems. They have a free and a paid version. Both work well.
I always wish Windows could warn ahead of time about long file names and the exact name and location of those f'ing files.
I'll try Teracopy, I remember reading good things about it .
There is another utility I use here at work that will handle the long file paths. It's called Viceversa pro. It is not free however but they have a 30 day trial. I use it for live backups. https://www.tgrmn.com/ https://www.tgrmn.com/web/kb/item31.htm
Teracopy will at least keep a log and you can go back and fix the problems and recopy.
There are a couple of other utilities that will help you identify the long file paths.
