Untar vzdump file for better deduplication

Hello everyone,

I'm testing borgbackup to copy our backups to some off-site storage. With the normal tar file and following ones, the deduplication isnt as effective as it could be. When I extract the vzdump and inserting every file one by one its much more space efficient. My question is now, could I run into problems when trying to tar them back into an archive (with tar cvpf) to restore them in the proxmox ui?

Thanks in advance

Greetings
