Compounding Storage Needs
Hidden Cost No. 1: Compounding Storage Needs
Retaining backup copies is now a necessity for many companies for a variety of reasons, from protection against human error, natural disasters and system failures, to compliance with regulatory or policy requirements.
The storage required to retain multiple copies of your backups can be substantially larger than the original source data. A common strategy for keeping data for long-term retention is the grandfather-father-son (GFS) backup scheme, which results in a lot of backup copies. In this scheme, a set of daily, weekly, monthly and yearly backups are retained using a first-in-first-out (FIFO) pattern. Even if only the data that is changing daily is stored in the cloud and the backups are being compressed, the amount of cloud storage used can add up over time.
Consequently, it matters a great deal where the gigabytes (GBs) and terabytes (TBs) you are purchasing reside. Most cloud storage and backup solutions charge for every GB of storage used in the cloud. So, as your backups grow and consume more cloud storage, so does your bill. But there are cloud backup solutions that only charge for the amount of data protected on the source side. Evaluate each cloud backup solution to determine whether you’ll be paying for protected data or raw cloud storage.
