The easiest way to back up Azure Storage is to copy the data from one account to another. Let's consider the following scenarios:
- Do you want to immediately restore your account in any region? If so, this section is for you.
- Do you only want to secure your data in case of catastrophic failure? If so, use GRS models for Azure storage accounts.
- Is it acceptable to only have access to a read-only copy of your primary data? If so, RA-GRS is something you'll want, without the need for additional backup.
- Do you want to secure your LRS accounts in case of accidental deletion or malicious activity? If so, continue reading.
Once you understand your scenario, we can focus on implementing a proper backup strategy. This is something you will have to implement on your own, so decide on the following:
- How often a backup should be made
- What data should be copied
- How to ensure backup correctness
The preceding questions are quite difficult to both answer...
