PR4100 best file backup software OS5

I have the PR4100 which was doing nicely with WD sync from my laptop PC. After I stupidly upgraded to OS5 and lost this feature I can only access my PR4100 thru my Android phone.

What Im wanting is the OS3 type back up of my laptop- maybe a few other PCs and remote access through my Android phone.

Which is the best software to use in my PC?

I see WD are suggesting Acronis true image. Is this a good bit of software to do my backups of My Documents and Pictures folders?

Will the already created folder on the PR4100 need to be erased of archived?
