Sync Files

Hi

I have two hard drives where I store files.

Hard Drive 1 - Main Storage
Hard Drive 2 - Secondary Storage

I deleted a lot of redundant files from drive one. Now I want the second drive to have the same files deleted.

There are thousands and thousands of files. Is there a way to sync without going through each file individually?

Thanks.

This batch script just copies the new files and changed files.

Code:

@echo off
:: Incremental_Backup.bat Created by Hackoo on 12/08/2017
:: It is a total copy first and then incrementally,
:: ie, it just copies the new files and changed files.

There are a number of applications that will do that. Some are free.

I use SyncBackFree and previously used FreeFileSync.

Any of these programs will give you a lot of control about what folders and file extensions are to be included or excluded, as well as the destination. You can schedule or run manually. Sounds like you want hard drive B to be a 100% match of drive A. That's normally called "mirroring", but there are other options as well.

Its simpler to use buit in robocopy /mirror option its built by MS for just that

You can now get a GUI for robocopy to make it simpler Robocopy in Windows 10 & Microsoft Robocopy GUI
