Hi,
Wwe have a customer using a lot of storage (5TB of storage when only backing up 500gb). The cloudberry tech said we had settings wrong and he had us review some documents about Block-Level Backups. I reviewed the documents and have a few questions that maybe someone could help me with.

1.) We are backing up a total of 500gb for a customer, but he is up to 4.7TB in cloud storage. I'd like to try able to restore 90 days worth of files for the customer. How can I setup cloudberry to save about 90 days worth of files?

2.) To save about 90 days of history, how many full backups should I do? 1 full backup every 90 days? or 1 every 30 days?

3.) Do you have a tool or know a calculator that would show me how many days I could save for a customer with 5TB of storage that has 500gb of data?

4.) I'm not sure what to set for Retention Policy, here is what I currently use:


5.) if I'm only saving about 90 days of data, what should my full backup schedule look like? Here is what I am currently using:


6.) since my customer has used up 4.7TB, I want to reset his bucket and start over, what's the best way to empty a Backblaze B2 bucket?


Thank you so much for any help you can give me.
