Thanks for getting in touch! Unfortunately I do not really have
an answer for you regarding this. Unfortunately it isn't just the
deployments per day that will have an effect. As a base for each
release we take a snapshot of data, so it depends on how many
variables you have for the project, how many steps, how many
packages. Then each deployment will also have logs and information,
so number of steps, your features and configurations, all will
again add to size and effect of a single deployment on the
One thing we do recommend is setting up retention policies and
not keeping all of your data on a long term basis. Things like
deployments to dev or test generally take up the most 'space' (for
lack of a better word) and are not generally required after a
length of time. We can understand keeping prod deployments forever
but again generally they aren't as long.
I can't give you any sort of estimate, but I would suggest
setting up as many projects and starting some deployments and
monitoring the size.
Sorry as I know it isn't the answer you want, but I have never
seen a customer installation that is the same as another so it is
very hard to generalise what is 'standard'.
