google app engine - How often should you backup appengine HRD data -

-

we have appengine app, has 300gb of data in hrd.. performed full backup google-cloud-storage every night. has become costly, costing 100 dollar per day.

i moved backup once per week. since data in hrd (high replication datastore)... there need backing data?

we cannot afford losing data of more day. thats why did daily backup. costs 100 dollar per day.

regarding hrd, iare backups needed? recommend.

i know business question too, has technical aspects.

data stored in hrd replicated in various regions, there no need perform backups, unless you're afraid data can modified / deleted via app or developers console.
