Uses filename to match.
Default: keep all backups

-x
Compress using xz instead of gz
PLEASE NOTE:
xz compression will take much longer and consume more CPU time
but the resulting backup will be about half the size of the same
sql file compressed using gz. Your mileage may vary.

-n
Skip reverse lookup of IP address for host.
