Lightroom 6 re-compressing backup script
View backup-lrcat
# This script re-compresses an Lr6 zipped lrcat file using xz, which is
# much more efficient. Oddly, it's actually more compatible, since Lr6.0
# uses a variant of Zip that won't even open using built-in OS X utilities.
# Open Lightroom and wait for it to exit. You must then say Cmd-Opt-,
# and tell Lr to "back up catalog when Lightroom next exits", then
# exit. If Lr is already running, this will just wait, so it is not
# important whether you run this script before or after Lr is running.
