Want to know to optimize cloud storage costs while maintaining immutability for your backups? 

In the december edition of my Regkey of the month series, I dive deeper in Block Generation 

I explain what it actually does, why it matters, and how a simple registry tweak can dramatically impact storage I/O and costs (sometimes for better — sometimes for worse).

If you work with object-storage backups (AWS S3, IBM Cloud, on-prem S3-compatible systems…), this one’s a must-read before messing around with default settings.

Check out the full post here on my blog: Advanced Object Storage I/O Optimization: Fine-Tuning Veeam Block Generation

Let me know if you like it, especially if you’ve already played with block-generation settings in production.
