i'm still very happy with NV, i did have to move a clients sites (4) off because of some weird email conflict which we couldn't figure out, once we moved it stopped?? still don't know why but i get less support calls from that client which was the ONLY one with the issue. i STRONGLY believe it was some setting in the clients computer we couldn't find.
i love backup buddy but it struggles repeatedly with their litespeed servers, it works and then it doesn't, it works but then the backup although says its good is actually missing small pieces and transferring sites fail, general the database fail on WP sites which is a major issue.
