Sync two NTFS hard drives in real time
Posted on 2013-06-23
I'm looking to replace my ReadyNAS NV+ RAID 5 unit for data backups. I'm currently 82% of capacity of its 1.3TB array. I have an old PC that I want to stick two 4TB hard drives in it, format them with NTFS and then have a program sync the changes in real time from one disk to the second disk. Currently, I use Freefilesync to sync certain folders from my 3TB data drive in my main PC to the NAS and from the NAS to a 2TB hard drive in a Stardock enclosure (in case the NAS goes belly up...I'm not sending it in to get fixed). This is a manual process. I want to setup one of the 4TB hard drives as a file share, dump my important files to this share and then have the sync program (preferably freeware) copy the contents to the 2nd disk.
I plan to install Windows 8 Pro x64 on the old PC and know that it has built-in RAID capabilities with ReFS, but I want portability and easy recovery. I want to take these disks and stick them into any PC running any version of Windows and pull the data off without any hassle. So far, the only program that I can find that does real time syncing is Yadis! Backup. Are there others? Is there a better way of trying to do what I am trying to accomplish?
