Putting dedupe to the test
With deduplication, you can shrink that load down.
We did some testing recently of CA ARCserve in our labs and came up with some
great numbers. Assume the same scenario as above: The terabyte backup produced
four times per month. For testing, we changed about 7% of the data in each backup
set. The first full backup set was reduced by a modest percentage to 910 GB.
(That "low" number was apparently due to the nature of the data in our backup
set, some of which could not be reduced by very much. CA claims that, in their
testing, they see between 50% to 70% reduction in the first backup.) Subsequent
full backups were significantly reduced given their overlap with data in the
initial full: to about 50GB each. The total disk requirement for storing 4 TB of
raw backup data was a mere 1.06 TB.
