I'm backing up my hard drive (all meagre 1.2tb onto my external 1.5tb drive).

However its not matching up,

I'm

1 folder, 13 files and 1gb from having a match.


Is there anyway to find these files without having to recopy over 140k files?


Windows 7 here btw.
 
I had this, pain in the backside. My problem was though it wouldnt copy over because the file path was too long, some files had unrecognised charactors.

What the hell!!! just back the f up :(

Thank god I use acronis on my server
 
I was going to suggest making some MD5/CRC hashes (creating them on the original data, then comparing them to the backup). But with that amount of data, it'll take a fair old while!
 
Personally I use Treesize Free, to spot the difference in fold sizes if theres a problem. I know theres a whole load of dupicate finding applications, but I dunno a good free one.

For synching external drives I use Karens Replicator. Again theres a bunch of alternatives, but I just like that one.

Most of the duplicated finders I've tried are not free. Anyone know of a good one that does files and folders?
 
There is a difference between synching drives, an exact copy etc. Usually only synchs what has changed, and/or deletions. and Backup software which usually archives files, usually with compression, and usually only archives the difference between the the last back up and the current one.

Corruption is a different check entirely. If there was a risk of synch or backup software corrupting data it would be useless and no one would touch it. It would take forever though as its a very slow process. Many of the duplicate finder apps to binary and other checks to see if the files, folders are identical. Not corrupted though.

When I moved to Windows 7 I had some issues with my external drives with files not being copied due to rights, and owership issues between the different drives. I made a new folder with Windows 7 and then applied all the same rights and ownership settings for that folder to my external drives. Then it worked ok.
