~~~~~~~~~~~~~~~~~~
Ceph ensures data integrity by 'scrubbing' placement groups. Ceph checks every
object in a PG for its health. There are two forms of Scrubbing, daily
(metadata compare) and weekly. The weekly reads the objects and uses checksums
to ensure data integrity. If a running scrub interferes with business needs,

cheap metadata checks and weekly deep data checks. The weekly deep scrub reads
the objects and uses checksums to ensure data integrity. If a running scrub
interferes with business (performance) needs, you can adjust the time when

are executed.
