Object Storage as Backup Target • Re: Capacity sizing for secondary backups to object storage with regular immutability, rather than daily backups

Hi Asahi,

Object Storage is always incremental.
The first Saturday will create a full backup, and on all subsequent Saturdays, the copy job will create incremental backups.
Each incremental backup will contain all data blocks that have changed on the production workload between the two job runs.
What is your expected change rate within one week? If you know the expected change rate, you can use the Veeam Calculator to estimate the amount of storage required.

I also suggest reconsidering only doing weekly copies to Wasabi. Having just one backup copy offsite per week could be risky.
For example, imagine a hacker attack on Friday. Would your business be able to recover if you had to restore from a 6-7 day old backup copy? I don’t know the specifics of your business, but companies processing hundreds of new orders per day could lose information about thousands of orders over the course of a week. A daily offsite copy could have saved them.

Best regards,
Fabian
