The equation is modified to account for decreased performance for incremental backups in the following result: CI = (T * CR)/25 ~ 14 cores (Cores required for incremental backup)Īs seen above, incremental backups typically have lower compute requirements on the proxy servers.Ĭonsidering each task consumes up to 2 GB RAM, we get the following result: ![]() CF = T/100 ~ 36 cores (Cores required for full backup) We use the average throughput to predict how many cores are required to meet the defined SLA. W = 8 hours * 3600 seconds = 28,800 seconds (Backup window in seconds) We need to change TB to MB / We need to change Hours to Secs D = 100 TB * 1024 * 1024 = 104,857,600 MB (Source data in MB) Our sample infrastructure has the following characteristics:īy inserting these numbers into the equations above, we get the following results. ![]() In this section, we will outline the recommendations to follow for appropriate sizingĬF = Cores required for full backup = T/100ĬI = Cores required for incremental backup = (T * CR)/25 Getting the right amount of processing power is essential to achieving the RTO/RPO defined by the business. In my previous Topic I showed how to use the Veeam Architects Site ,but how does it give us the amount of Cores and memory that the proxy will use? I'll show you …
