Hello Dears,
i am planning to introduce some backup system/procedure for a couple of server we have at our company.

2 servers HP UX
2 servers Solrais
1 server IBM

i was thinking if there is a good product/hardware that can manage these from a centralized interface and perform
1- a system image in case of faiulure
2 - data backups

i am not sure if it should be NAS or Tape or any other , since one of the reason i am asking is because the lack of knowledge i have.


Please Advice
