Yes, there was no breaking protocol change so you can backup from a PVE 7 to a PBS 1
and from a PVE 6.4 to a PBS 2

In theory yes, but in practice no, at least for the build .deb package we provide.
You can build it for yourself from the source code, you may need to at least adapt
the zstd library usage to a lower version again to be compatible with the one Debian
Buster ships.

FYI: PBS 1.1 will receive important bug fix and security updates until end of Q2 2022,
so it still can be used just fine in PVE 6.4.
