Here is how you calculate the backup size from the data size (it's not exact because the dedup factor could be 4.8612125451222 for example)


I guess if you want to calculate the savings, you take the datasize before deduplication and after deduplication and subtract them from each other

Code: Select all

$datasize = 127GB
$deduplication = 4.9
$compression = 1.8
$backupsize = $datasize/$deduplication/$compression
$backupsize/1GB

$dedupsavings = $datasize - ($datasize/$deduplication)
$dedupsavings
$dedupsavings/1GB
