Thanks for taking the time to reply. I'm not sold with the synology for the reason that I already have a ds211j but while its ok for backups it has its faults, it just does not seem to intergrate properly with apple gear and when backing up it can just loose connection at time.
What do you think to this idea?
I already have a Mac mini so would get osx server and connect an external drive via thunderbolt cable. I could then put files from all computers onto the drive and have it running in raid so it automatically has a backup. Am I right in thinking that I would not need time machine if running raid.
My partner likes some of the features in mac osx server like the wiki which would work really well for the business.
