Summary
Continuous data integrity checks
Disk scrubbing (software)
Details
Datrium DVX was designed to host mission critical production workloads and data. Therefore the solution continually verifies the integrity of
the entire filesystem, several times a day. Every object in the system is reference checked to make sure that its data is safe. The data for every live VM is referential-integrity checked, as well as all VM snapshot data. The crypto hashes make the verification quick, easy, and complete.

This continual filesystem verification is done in addition to disk scrubbing. The disks are proactively scrubbed in the background to detect and fix LSEs. This scrubbing happens slowly so as to not impact the incoming workloads. The scrubbing also verifies the integrity of all the erasure coded RAID stripes so that there is confidence that drive rebuilds will be successful.
