Today, let's talk briefly about data volume and bandwidth requirements.
The formula for calculating the theoretical transmitted data volume is as follows:
Theoretical Transmitted Data Volume (GB)/hour = [(Bandwidth÷8)×60min×60s]÷1024
Theoretical Transmitted Data Volume per day = Theoretical Transmitted Data Volume (GB)/hour×24 hours
PS. Hmm, do you need to derive the formula? Go ahead and derive it...
- 1Mbps = 1/8 MB/s (when converting b to B, remember to divide by 8, this is easy to overlook)
- 1 hour = 60min*60s
- 1GB = 1024MB
The theoretical transmitted data volume is the maximum value obtained under the most ideal conditions, that is, 100% bandwidth utilization and uninterrupted data transmission. In actual situations, considering network fluctuations and the inability to fully occupy the bandwidth, backups are generally not executed continuously for 24 hours. The estimated actual transmitted data volume will be significantly lower than the theoretical value. Therefore, when calculating the estimated transmitted data volume, we can use an 80% bandwidth utilization rate and a backup window of 12 hours. The reference formulas are as follows:
Estimated Transmitted Data Volume (GB)/hour = Theoretical Transmitted Data Volume (GB)/hour * Bandwidth Utilization Rate
Estimated Transmitted Data Volume per day = Estimated Transmitted Data Volume (GB)/hour×Backup Window Hours
From this, we can draw the following conclusion:
