Backup/synchronize

I want to backup my 2TB external HDD, 1TB laptop HDD and 64GB Android Phone ROM to an external 5TB HDD.

I want to set the backup in a way that whatever files are created/added, deleted or edited, including moving files/folders to different locations are reflected on the 5TB backup drive. It should also be compatible with Windows and Linux.

The backup software I use is EaseUS Todo but i found out that it won't deleted from the backup the deleted files from source. Example, I first create a full backup. Next if I delete a file from the source, that file is not deleted from the backup image. This means eventually my 5TB will be full of unwanted files which I would not want to restore.

I think synchronization software is what I'm looking for but backup and synchronization has been interchangeability used which is why there is a confusion here.

Please let me know any software which would fulfill my requirements.

 

Backups are usually images used for recovery. Syncing is usually mirroring files / directories. You're right images are not changed when files are modified - they are a snapshot in time. For Windows you could use Robocopy (Robomirror at Sourceforge). I am not a Linux guru but you can find a simular command and cronjob maybe? Android, I do not know either.

Take look at Syncback Pro or https://www.dirsyncpro.org/index.html

 

Thanks, I did some research and have found FreeFileSync to be quite good and is compatible with Windows, Mac and Linux. It can also sync mobile devices like phones and mp3 players, camera, etc.
