How to find how many attachments you have in Confluence Cloud and how much space are they using

[#1]

Considering the published limitations of Atlassian Backup and Restore ("data size of up to 32 GB(!?) and attachment count of up to 7 million"), I thought it might be useful to figure out how many attachments we have in Confluence Cloud, and also how much space they take up.

Spaces Report is your friend

If you generate and download a spaces report for all of your spaces, you can then open it up in Excel or Google Sheets and SUM up the Attachments column.

Notes

Storage usage

So, if you go to your Site settings at admin.atlassian.com you can see storage usage under Storage. This includes a total of all disk usage, including "pages, live docs, attachments, files, and comments".

Missing data

Neither the Spaces Report nor the Storage usage page include "data size", which I think means the size of the database for Confluence (which has a 32GB limit).

Confluence stores pages and comment data in the database. So if you have a lot of pages, or a lot of long pages, this might be a lot of data. Apparently it's enough for our site to make us ineligible for backups. :-{

One space at a time

It was previously suggested that you can get a count of attachments on a per-space basis, or using Search. This seems... cumbersome.

Current usage:

Confluence: "1.1 TB of unlimited GB used" 👀

What is this "32 GB" Atlassian is talking about? 😄

@Darryl Lee we have built an app for Confluence called Attachment Manager that among other things allows you to see total size (including per type) and total number. Then tools to bulk manage attachments to save storage, improve performance and eliminate confusion.

Here are the space level stats.

You can do useful things to clean up attachments like filter by unused (shows only attachments that are not visible on any page).

Soon it is going to work across all spaces as the same time (global page) and will become part of Space Content Manager.
