Assuming a customer's initial backup capacity of 1TB, the average daily data increment of 10G, with a backup strategy of once a week for all the equipment once a day from Tuesday to Sunday. All reserve and additional backup data are stored for 4 weeks, regardless of deduplication / redundancy ratio / replication, etc. Calculate the required back-end. The capacity should not be less than ______. This 1TB is calculated according to 1000G.

The initial backup is 1TB (1000G). Daily increment is 10G, so weekly increment is 60G (6 days). Weekly full backup is 1060G. Over 4 weeks, this is 4240G. Daily incrementals for 4 weeks are 240G (6 days x 10G x 4 weeks). Total is 4240G + 240G = 4480G. Adding the initial 1000G gives 5480G. The closest higher option is 5940G.
