These estimates also allow for the fact that deduplication and compression will provide significant space savings. This allows for 20 revisions with an average of 5% data change per backup, plus an allowance for a space management. For example, if you have a data source of 200GB you should expect to need, over time, 300GB of storage capacity. ![]() When planning your backup storage capacity, you should consider both the size of the data source that is being backed up to the cloud and the space that will be needed as data is added each time a backup runs, which will depend on the job’s retention scheme.Īs a guide, for every 100GB of source data backed up, you should allow for 150GB or storage. This resource provides guidance on what values to use in the AWS and Azure storage calculators and what capacity you should plan for. When using cloud service providers like AWS and Azure, you may need to estimate how much storage you require for your backups and how much that storage will cost.
