The rsync documentation says: "O, --omit-dir-times This tells rsync to omit directories when it is preserving modification times (see --times). If NFS is sharing the directories on the receiving side, it is a good idea to use -O." What's the underlying issue behind this recommendation? I've got an existing script I wrote that runs rsync between two isolated hosts, that I'm adapting to run between the nfs servers for two small clusters of web nodes. I'd like to understand the pros and cons. I'd like to preserve directory times for historic reasons, but I could live with only syncing them up occasionally, and I don't want to cause serious problems. -- Albert Lunde albert-lunde at northwestern.edu atlunde at panix.com (address for personal mail)
