Backup should resume from last failed state

Consider that incremental backup is happenng for 10 tables for a set of 100 WALs. if backup @ 10th fails, then on net iteration it would be triggered again from 100 WALs + new WALs all tables
This is a issue because resource and time used to do he backup of 9 table & 100 WALs are wasted

Rather it should have functionality to resume from previous state complete that backup and then do new set of WALs. This will make it more performant
