Yes, it's just a recompile and install. No config changes at all.

With the default configuration, it will take between 24 and 25 hours
for this file to be updated. This is because the file is 'continually'
updated, so bbackupd holds off backing it up until it settles, which it
never does, so eventually it uploads it anyway. Adjust MaxUploadWait to

you need to build things a little more manually:
Then use the executable in boxbackup-0.03PLUS2/debug/bin/bbackupquery
