Hi, I've read that Azure backup is incremental, how it is managed?
It's important to calculate the cost
Let's use a daily backup with 7 days of retention time, 1000GB VM data and 5Gb of increment as an example.
- Day 1 full backup of 1000GB
- From Day 2 to Day 7 incremental of 5GB and I reach 1030GB of quota and the retention reach 7 days
- Day 8 full backup 1030 (total amount of data is 2060GB couse if the first full is deleted I don't have 7 days of retention)
- Day 9 to 14 incremental of 5GB, total amount of data is 2090GB and the retention is 14 days (even if I choose only 7)
- Day 15 incremental of 5GB and deletion of the first full backup so I have 7 days of retention and data goes down to 1065GB
Is it right or the process is different?
Cheers
