Hi, I want to perform a backup through asbackup but at first I want to estimate the volume of the backup file. On one of our production clusters we have 23 nodes with replication factor of 2, on the AMC I see 13.14 TB Cluster Disk Usage and 1.34TB Cluster Ram Usage. We use a single single namespace that has over 11 bilion of records. When I run the following command: asbackup -n <namespace_name> --estimate and I see to following output:
2017-02-02 12:47:53 GMT [INF]  Backed up 10000 record(s), 0 secondary index(es), 0 UDF file(s) from 23 node(s), 6500722 byte(s) in total (~650 B/rec) 2017-02-02 12:47:53 GMT [INF]  Estimated overall record size is 679 byte(s)
I don`t think that these numbers add up, how can I find an estimation for the backup that would be as close as possible to the real size?
EDIT: If I understood it correctly, the backup size is 679*11,000,000,000 (~number of records), which ends up as 7.469TB. Did I got it right?
