what you also can do if you worry about the unexpected side consequences is to
make a fake database host in hdup.conf:

[hostname-database]
tar = /my/hacked/tar/version
dirs = /database/files

and use that host for the database backup. For the other backup
you can still use the normal host directive and maybe exclude the
database directory,
