Wanting to do network backups
We have a need to backup our office data spread around some 10 PCs in different rooms. I have considered a NAS server but this just deals with data backup. I am wondering that we may need other cerntralised software (e.g. CRM) so am considering a Linux server.
At the moment all the folders and files are on individual machines. How do these get rearranged so that we can network (share) all of them and arrange backups?
Are they all ported somehow to the server?
Are they all synchronised somehow?
When someone opens a file for editing is it opened from the server or a local copy?
