Splitting Large Jira Cloud Media Restore Folder

[nojansen]

Hi all,

I am in the process of writing a script that will split our backup file into multiple media files as per https://confluence.atlassian.com/cloudkb/how-to-import-only-part-of-a-jira-export-into-jira-cloud-859461966.html, as we have a lot of attachments which are fairly large.

My potential problem is that I have a "10000" folder for one of my projects that contains over 50GB of data.

Am I able to split this folder over two media-only-x.zip folders?

It would be great if Atlassian clarified how data is restored from these files... Does it simply look for an issue key under a project key and overwrite the corresponding attachments?

Cheers
