This is sort of two topics in one. The specific feature request, I'm surprised there doesn't seem to be any posts about. The general request doesn't quite have a post, but is scattered across several posts.
Specifically: Exporting a backup CSV, and immediately trying to import that same data fails miserably. The import fails to recognize most of the exported fields, notably space, list, and project names which are extremely important (among others). It should just recognize immediately that it's a clickup export and import everything out of the box. Seriously, one click to export, 3 clicks to import... should be all it takes. Either that or find some way to add comprehensive source control and versioning.
Generally: why aren't backups FULL backups? Including docs, attachments, embeds, other views, etc. I should be able to entirely delete an account and restore everything in a new account with ease (of course, attachments could be large, so there should be an option to ignore them). Not only this, but we should be able to backup only a workspace, only a space, only a folder, etc.
I'm hesitant to put any amount of important data into clickup knowing that if for any reason someone screws something up or something causes data loss, there's no good way to ensure I'm able to restore all of it.
