How to add second storage to existing backup jobs

I have 10+ backup jobs running under WEB UI, backing up set of folders to three different repos in the cloud. I want to start backing them up to three identical local repos. I know there’s “copy” command for CLI, but I’m confused - how do I employ this command with web version?

A copy job requires two storages, one source and one destination. So you’ll need to add a destination storage that is copy-compatible with the source storage after which you’ll be able to create a copy job.

So, I create second copy-compatible storage once (storageB) using add -copy, then after each backup to storageA I issue copy command -from storageA -to storageB?

That is basically right, but a copy command will copy all backups from A to B unless you specify the -id option: Copy command details
