How to verify a backup from Bareos/Bacula?

Question

Backup

Good day!
For backup use Bareos(Bacula) on hdd. I wanted to check the integrity of the backups.
Ideally, I think, check the hash between the backup and the physical file on the machine.
I want to check full copies. Organized on the basis of one complete backup file with one task per machine.
Those. in one file there is no heap of different tasks and files from different machines.
Actually, the question is how to organize a check without restoring this backup somewhere and not drive a bunch of traffic over the network? Ideally, as I see it, collect hashes on the client, throw it on the server, collect hashes from the backup on the server, compare.
On Ubuntu clients.
