Best way to created a backup of a new drive
 

I've got a 1.5TB drive with about 700GB used, I bought another 1.5TB and did a backup but it took over 24hrs for the whole thing, it averaged about 20GB/hr transfer... but when I manually move files over it moves a lot faster.

Unfortunately, the backup I bought is a faulty and I'm going to have to return it. I'm a little scared of running another 24+hr backup and was wondering if there's a faster way to do it.


Also, if I manually moves files over, then run a smart update, will SD delete what I've manually moved and try to run them through SD? I could have sworn in the past when I've done this SD deleted my old files and copied them again thru SD. Any help is appreciated

yikes, sorry about the spelling in the title

I don't know what kind of drive you copied to, or how it was connected, but I'd generally expect 8-12MB/s to a quality external, sometimes faster.

If you manually move files to the right place and they're correctly copied (all data/dates/etc correct) we won't replace them.
