Hi, I have two internal mirror, one mirror are working (using rsync 3.1.0-ubuntu0.2) and the other are using rsync 3.1.1-3ubuntu1. The latter are always throws this error: rsync: You may not combine multiple --delete-WHEN options. rsync error: syntax or usage error (code 1) at main.c(1572) [client=3.1.1] Tried to find "--delete-WHEN" in the ftpsync, but none found. Anyone experience the same? Thank you Budiwijaya
