This site is running on an Azure Basic A2 VM with 127 GB of storage. I back it up in two ways:
- There is an Azure Backup (AB) agent installed in the guest OS, and that backs up an export of MySQL and the IIS content.
- I use the (preview) feature that allows you to grab a daily backup of a VM. This is what I want to focus on.
I have deployed a GRS backup vault. The usage summary is:
The storage cost of the backup this month will be around €2.5776 (72 * €0.0358 per GB) and the instance cost will be €7.447 (The VM size falls into 50-500 GB).
There is a daily backup with 4 weeks of retention. Right now, there are 29 days of history:
Backup can be slow (ranges from 47 minutes to 4 hours and 13 minutes), but I haven’t had any issues.
I haven’t had to do a restore, but so far, so good.
