CDP Quick Tip #7 – How to Determine Amount of Storage Needed to Backup X Servers

Posted by R1Soft on Aug 9, 2010 12:00:00 PM

Need help determining how much storage you will need to backup X amount of servers?

Here’s a quick tip from the Head GEEK that will help you when analyzing capacity planning requirements.

If you’re determining how much storage you’ll need on your server, the best approach is to get a benchmark or average data change in your environment. R1Soft CDP recommends you use the following example and formula to obtain your benchmark.

For example: If you have 1TB disk, about 400GB of data at any given time, and the average data change between backups is 100MB and you wish to keep 30 recovery points. The equation would look like this:
EX: (1TB * 5%) + 4OOGB + (100MB * 30) ~= about 1.2TB per server without compression. Using even lower levels of compression, you can cut this amount by 50 percent.

You should note that when you take a snapshot, there is a little overhead for the actual file system formatting (about 5% of disk size).
