Do you have a chart for Bandwidth Requirements?

It is very difficult to analyze those requirements because of all the variables added by FastBIT. However, the basic formula is pretty simple: Take the expected size, in MB, of the data you might see in a day, divide it by the amount of seconds in the day and divide that number by 8 to obtain MB/Sec Bandwidth. This will result in the required bandwidth (MB/Sec) needed to sustain 100% load throughout the day.

Example: If we have 500 users sending us an average of 600MB per month (this is about what we see at the Steelgate Online Center), then the formula follows: 600MB * 500Users = 300000MB (300GB) / 30days (per month) = 10000MB Per Day (10GB) / 86400seconds (1 day) = 115.74Kb/sec * 8 (to convert to MB/Sec) = .93MB/Sec or about 61% of a full T1. It typically gets a bit peaky around noon and around midnight, so to accommodate the mean, you should probably have a 30% overhead, which in the above case, would translate to just about a full T1 (1.5MB/Sec).


Does it make sense to use Cloud Backup if you have a slow Internet connection?

Depending on the speed of your connection and the size of your backup, your initial backup over the Internet may take several hours. Many people with large backup sizes and slower Internet connections will often run their first backup over the weekend. Once the first backup is completed, each subsequent backup is usually a small amount of data that can be backed up in just minutes over a slower dialup connection. 

Our software can also resume a canceled backup, so you can start the backup during your slow times and cancel it during your busy times. The next time you start the backup, it will pick up from where it was canceled until the entire backup is complete.
