We read delta - just changed data since last backup

Every backup is FULL!

It does not matter if we have read only change data or everything. On Data Domain is always FULL backup – exactly the same as we have read all data from Share/NAS – 100% the same format in both cases on Data Domain

Dynamic slicing

Data are read in parallel

PPDM divides dynamically protected NAS assets into slices by using max values for each slice:

* 200 GB

or

* one million files

There is tolerance of up to 30% to avoid creating nonoptimized slices. For example, a single 260 GB folder is still within the 30% tolerance value and would be considered one slice. Each slice uses one stream.

Dynamic slicing

Each protection engine has 24 parallel streams. We can assign number of streams for particular NAS asset – maximum number of dynamic slices.

By default, PowerProtect Data Manager allocates eight streams per NAS asset (max 256), per backup operation.

For restore operations, the default is eight streams for share-level recovery and one stream for FLR.

We can deploy more protection engines.

When calculating the number of NAS protection engines, allow up to 120% to 150% of the estimated slice count for overhead such as placeholder slices.
