can I add DWG file from Autocad into Confluence?

[Harshini T]

Is there any restriction on the file types we can to Confluence? 

[Nic Brough -Adaptavist-]

No, you can attach any type of file.

[Harshini T]

thanks nic, how to retrieve and backup the files frequently?? 

[Nic Brough -Adaptavist-]

To "retrieve" them, click on them and Confluence will provide a download of the file.

For backing up, follow the standard Atlassian recommendations for backing up Confluence.

CAN'T WE an enitre space at a time? should we download them individually?

[Harshini T]

is confluence designed for enterprise content management or what is the main purpose that confluence is designed for?

[James Dellow]

@Harshini T Confluence is an enterprise wiki, which includes the ability to manage files (as attachments to pages). Attachments on the same page, with the same name are versioned. Confluence is also extendable and there may be existing apps (some free, others commercial) that can support your specific information management requirements. Check the marketplace https://marketplace.atlassian.com/

In respect to backup, you've indicated that are using Confluence Cloud - this is a managed service, so please refer to the following information about how Atlassian backup your content https://confluence.atlassian.com/cloud/data-storage-faq-873871367.html#DatastorageFAQ-HowoftenisdatabackedupHowoftenisAtlassianClouddatabackedup?

As @Nic Brough -Adaptavist- indicated, you are free to make copies of your site as required https://confluence.atlassian.com/confcloud/create-a-site-backup-724765526.html but this isn't intended to provide you with an automated backup (you are already paying Atlassian to do this for you).
