Local account vs Service account for DNAS protection

Hi,

I was interested to hear from the community as to if people tend to use local accounts or service accounts when it comes to configuring snapshot style protection for DNAS backups? Previously when we used ndmp we obviously had to use local accounts that were local to the storage array but we want to test moving away from NDMP to DNAS and as such it seems you can give it either local or domain based user so long as it has sufficient rights on the storage array. So what do people tend to use and for what reasons?

Thanks in advance for any opinions/info
