# cPanel API 2 Functions - DiskUsage::buildcache

Warning:
The cPanel API 2 system is deprecated. We **strongly** recommend that you use [UAPI](/cpanel/introduction) instead of cPanel API 2.

## Description

This function rebuilds the account's cache of disk space usage data.

Warning:
We **strongly** recommend that you use [UAPI](/cpanel/introduction/) instead of cPanel API 2. However, no equivalent UAPI function exists.

Important:
When you disable the [*File Storage* role](https://docs.cpanel.net/knowledge-base/general-systems-administration/how-to-use-server-profiles/#roles), the system **disables** this function.

// Rebuild the disk cache.
$rebuild_cache = $cpanel->api2(
    'DiskUsage', 'buildcache'
);
```

Note:
For more information, read our [Guide to the LiveAPI System](/guides/guide-to-the-liveapi-system/#guide-to-the-liveapi-system).

LiveAPI Perl Module


```undefined syntaxhighlighter-pre
my $cpliveapi = Cpanel::LiveAPI->new(); # Connect to cPanel - only do this once.

# Rebuild the disk cache.
my $rebuild_cache = $cpliveapi->api2(

cPanel Tag System (deprecated)

Warnings:
- cPanel tags are **deprecated**. We **strongly** recommend that you **only** use the [LiveAPI](/guides/guide-to-the-liveapi-system) system to call the cPanel APIs. Examples are **only** present in order to help developers move from the old cPanel tag system to our [LiveAPI](/guides/guide-to-the-liveapi-system).
- cPanel API 2 calls that use cPanel tags vary in code syntax and in their output.
- For more information, read our [Deprecated cPanel Tag Usage](/cpanel-api-2/cpanel-api-2-deprecate-cpanel-tag-usage/) documentation.
