Well depending on your PG version you could read up about the various
backup methods. I believe you'll be interested in 24.3 there when you
ask for WAL archiving. The good thing is, its useful for DBs much bigger
and especially for those that 'cant' go down for even a minute, but yes
it has its trade-offs. (Its not that bad actually, but its a call you
need to take).

You could club the pgdump / gzip in one step, thereby avoiding extra
writes to disk. The URL below should help you on that (pgdump dbname |
gzip > file.gz)

You could also do a
pg_dump -Fc | gzip -1 -c > dumpfile.gz
at the cost of a slightly larger (but faster backup).
