Target Volume Does Not Support Windows Deduplication (code 2050)

Situation

A restore plan finishes with the following warning: Target volume does not support Windows deduplication. Failed to restore some files from disk with Windows deduplicaton to a disk that does not support Windows deduplication. {0} files were not restored

Cause

This occurs in case the target disk does not support deduplication. Data Deduplication helps to reduce costs that are associated with duplicated data. Duplicated portions of the volume's dataset are stored once and are (optionally) compressed for additional savings. These dublicated portions cannot be restored to target that not supports deduplication.

Solutions

Enable deduplication on selected target volume
