Hi,

I want to check my copy command before I back up all my data from one drive to another. I'm also interested in validating the data that is copied, so if theres a way to check that, please let me know!

Command: cp -R /mnt/driveA /mnt/driveB

Thanks

My thinking is that you'll use md5sum and have to write a simple script to compare the two directories.

thank goodness for google, someone's already done it:

If you run the script and get no errors/output, its 100% verified. If there are problems, it will tell you what they are.
 
rsync -avP /source/dir/ /dest/dir

be careful with the /'s. How I posted should work well.
