# Cleanup of deduplication data

## Cleanup function o**verview**

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.

{% hint style="warning" %}
It is important to note that after removing backup plans (or parts of them) that used deduplication, you should run cleanup.
{% endhint %}

{% hint style="warning" %}
Starting from **version 2.0.0**, **disk image** and **VMware** backups use a modernized data format. As new backups are created in this format, **legacy deduplication data becomes obsolete**. Once your retention policy clears older backup versions, we recommend running a **cleanup** to remove redundant data from both the storage and local cache.
