Data Compression Level
Data compression levels can be used to configure the compression ratio. Higher the compression level, the more time it will take to compress the data.
Note: The compression ratio would differ based on the backup type. When backing up machines that only have files and folders, you may expect a compression ratio of 60 to 70%. If you have machines running Exchange, SQL, etc., you may expect a compression ratio of 50-60%. On average, you should notice a compression ratio of at least 50%.
For example, if you set the compression level to ‘Low,’ you’ll obtain about a 50% storage reduction. You will get an extra 5% storage reduction if you set it to ‘Optimal,’ and a 10% storage reduction if you set it to ‘High.’ This is a rough estimate based on our test results. The compression ratio would differ for each customer based on the data type.
The higher the compression level, the longer the backup will take to finish. To achieve a better compression ratio and at the same time for better backup performance, we recommend maintaining the settings at the ‘Optimal’ level.
You can click on Edit and choose to modify the levels and update. The levels can be chosen from being high, optimal, and low.
