Backup of LTR data

I need documentation or proof of some sort that restoration from a tape backup of an LTR repository is approved & will work. Yes, we will rely on the LTR repository machine for our long term storage. However, if there is a tape backup of the physical repository machine, can I restore that machine from tape in order to have access to the Zerto LTR data?

The need would be redundancy of the repository.
