soft for simultaneous copy

[thefisl]

Ok, so I need to find some software that would allow me to copy the information on an external drive of somekind (i.e. thumb drive, CF card, etc...) to my laptop drive AND to an ext usb drive at the same time. As it is right now, I will dump the files to my laptop and then copy them to my external. I only need to have the copies on the drive as backup and will only be there until the job is done. I just don't like spending the time doing two steps as it is usually about 10 gigs or so that I do. Please help. thanks

Script it

i am assuming you mean create a script that would have it copy to one and then once that is done have it copy to the other making the process automatic.... my issue is that i don't want to spend the time to essentially copy twice the data.... i want it to copy over in one go.... i dump the files and then shut off my computer....

Do you mean you want the data to copy to two locations concurrently? So, say it takes 10 mins to copy the data from your source to your destination you want to copy to two destinatons in 10 mins? If so, I don't think you'll find what you want. You're going to be limited by the bus speeds and traffic. As it is, copying is going to go as fast as it can and if you start two copy operations, you're sharing the bus so each copy will have less of the resource.

You know you don't have to wait for a copy to finish to start a second one right? You can already just perform two copies and let the OS do it as fast as it can with the resources it has.

If you want to automate it, have you looked at Syntoy? You could setup two sync rules from the same source.

Usually copying is slowed down due to the slow speed of the physical drives, not the bus themselves.

individual copy time is gated by drive access time, yes. Time to complete concurrent copies will be a function of drive contention and bus contention between the two operations ontop of drive access times. The point is that the use of resources by one operation will slow down a second concurrent operation depending on certain factors. The time difference between two concurrent copies vs. two sequential copies may not be significant and if the goal was to halve the time to copy by doing it concurrently, it may be an impossible goal.

Then again, it might not and is why I suggested trying two copies.

uhh make a script and when its complete tell the computer to shutdown in the script
