do you see network saturation, io saturation ?
generally faster hardware i.e striped and or nvme disks along with a robust
network link and capacity should help get the backup done quickly.
where are you taking the backup from? is the server busy doing other work
or it is a dedicated machine for backups ?
basically monitor for resource saturation, if all looks good, we could take
basebackup of a 10tb db in 8 hours, and in another case on a slow remote
storage, backup of 2tb took 1 day.

now, pgbackrest can speedup backup processes by spawning more workers for
archiving and stuff. we have taken backup on nvme disks striped of 28tb in
3 hours, bare metals servers with powerful cpu.

so , it's hardware .... else switch to pgbackrest which can take
incremental/differential/full backups.
there are other tools too, I used only these two.
