Do I need to create full backup regularly? I do not see such option. But AFAIK, when using incremental backups, time to time full backups should be taken. Is this same with pbs? Or I can just leave it one full backup and let rests for incrementals?
 
Each and every backup to PBS does only transfer modified data - call this "incremental".

Each and every backup to PBS is presented to the user as a full backup.

This "magic" is part of the basic concept of this software. Please compare https://pbs.proxmox.com/docs/introduction.html#main-features

So you mean I do not need to worry about how old (xx days) first full backup is. ?
Correct.

When you run a new backup the already present chunks (on the destination) are not transferred again but only "referenced". But they are verified. (Actually I am not sure about this, but a "verify" will do this definitely.)

At the end this new backup contains references to each and every chunk which is required to restore it some time in the future.

And of course: when you delete the old/first backup these chunks will NOT get deleted.

Best regards
