I'll stick with 2011 for a while.....no problems here at all.
I run 3 different Acronis backups.
Data backup every evening (full on wed. then 6 incrementals)
Full System & data to Local HD every Friday evening (I usually have a months worth on disk)
Full System to external Drive every Sunday night (also keep 4 or 5 previous)
Data....I don't do music, pictures or video in my backups.....I sync them amongst my computers across the LAN instead using Allwaysync....lunchtime daily
