You should of course follow Kovid's good advice. Having said that, I myself am somewhat hypocritical. I have been keeping my Calibre Database on an NFS share on my QNAP NAS for years without a problem. I run Calibre mainly on one particular Linux Box, but I do have it installed on others. I also backup the whole calibre directory including the database files regularly to a local machine via rsync, and keep separate backups of several versions of the database files. Problems are typically with corruption of the database rather than damage to the actual book files and directories. Having the database on an NAS is not supported and frequently does lead to problems, though I haven't experienced any significant ones personally. If you do run the database on the NAS it is better to run Calibre only on Linux machines or Windows ones. Mixing them frequently leads to problems. As mentioned, I always use NFS shares rather than CIFS, though people do use CIFS shares also. I also run COPS which I use to access my books from ereaders, phones and the odd windows machine when I really must.

People do this with mixed success. If you want to try it you do so at your own risk and have no right to whinge if things go wrong. Keeping a backup of everything is a must. Murphy's law frequently comes into play, though sometimes I almost believe that it is more likely to come into play when you don't have a good backup.
