Azure backup Service Notes

Azure IaaS Backup:
  • Recovery Services Vaults
  • Off site protection (Azure data center)
  • Secure
  • Encrypted (256-bit encryption at rest and in transit)
  • Azure VM's or VMS' woth SQL and on on-prem. VM's or Servers
  • Server OS supported: Windows 2019, 2016, 2012, 2008 (only x64)
  • SQL all the way back to SQL 2008 can be backup
  • Azure Pricing Calculator can help estimate backup costs
  1. Azure Backup Agent (MARS Agent), used to backup Files and folders.
  2. Azure Backup Server (trimmed down lightweight version of System Centre Data Protection Manager (DPM)), used for VM's, SQL, SharePoint, Exchange.
  3. Azure VM Backup, management done on Azure Portal to backup Azure VM's.
SQL Server in Azure VM backup, used to backup SQL databases on Azure IaaS VMs.

Backing up Azure VM's must be done to the same geo location as the vault.  It can't cross geo-locations.  Recovery has to be to a different location (verify this is correct?)
Note: "Backup Configuration" setting of the Vault properties can be set to "Geo-redundant"

Azure Recovery Vault Storage choice:
LRS - Local Redundacy Store - 3 local async copies
GRS - Globally Redundant - 2 async copies in the same data region with 3 local copies- so can keep in Europe for compliance, all 6 copies are in Europe.
Update Feb 2020: I think there is also a GZRS option, check if this has changed?

Naming is absolutely key and having a logical hierarchy within Resource Groups so it is easy to find resources.  I focus on naming my resource consistently however, I've always felt "Tags" have little or no purpose in smaller environments.  In larger environments tagging can be useful for cost management, recording maintenance, resource owners, creation dates.  Lately, I've been finding it useful to mark my resource with and Environment Tag to cover my Azure DTAP scenarios.  E..g., Production, Testing, Development.
