It's not clear from the documentation, but looks like the shared flag only makes sense if the storage is for vm disks, so PVE would know not to copy the data if a vm is running on a shared storage. The question is whether it is needed to tick "shared" if it's a shared storage for backups? Does it do anything in this case?

Did you encounter any problems regarding the backup with or w/o this flag?
"Shared" just tells the PVE software that this storage is available on all (or a subset) of the nodes of the cluster. Not more.
One pitfall for new user is that one might believe that this actively shares a storage between nodes - which it does NOT.
