NetBackup – Basic Architecture – How Big? Master

Media

86400 jobs per day (based on 1 job per second) Catalog size of 750GB +-

150+ per Master No real limit on disk STU’s 256 tape drives per Media Server LAN/HBA/PCIe limits are variable Number of Clients based on bandwidth









Server Choice Overview - Master As Always – Always – “It Depends” • Master specifications are based on: – – – – – –

Number of Clients Amount of data being backed up Number of tape drives Amount of disk in DSU’s Number of Media Servers being managed Number of jobs per day









Server Choices – Media Server Again – Again – “It Depends” • Media specifications are based on: – – – – –

Bandwidth coming into server (normally LAN) Amount of data being moved What else is running Tuning goals Bandwidth out to tape drives/disk

Rule of Thumb:











Basic NBU Server Choices - Examples • Master or Media Servers: – Windows/Linux - HP ProLiant DL580G8 • 4 CPUs with up to 8 cores on each











Advanced NBU Servers – Recommendations • What if you want to run MSDP? – Same CPU recommendations as a normal media server BUT you need 1GB RAM for each TB of disk storage for f or cache – Dedupe hashing does not really put much load on a modern server











How To Move A LOT of Data? SAN Media Server











Tuning – What does it mean? • Tuning is more than playing with buffers path – end end to end – end – is is adequate – It is about making sure that the path –

• What works for you may not work for someone else











Tuning – NetBackup • Out of the box, NBU is partially tuned, but it needs more • No exact recommendation. Testing is needed for high performance • Think of Data as a Pool of Water and Buffers as Buckets





























































NBU Buffer Tuning – Increasing VM Backup Performance
