Cleanup of deduplication data

This article explains how to remove residual files left after deduplication from storage.

Cleanup function overview

The cleanup function in Xopero ONE removes residual files left after deduplication. While deduplication reduces storage requirements by eliminating duplicate data blocks, it can also leave behind orphaned files with no further use. Over time, these files may accumulate and occupy space required for new backups, which can result in reduced storage performance.

It is important to note that after removing backup plans (or parts of them) that used deduplication, you should run cleanup.
