Question on folder sync with "directory name translation"
I should describe the problem more in details, but I believe this is off topic for this list. The FolderA is named "Musica" (in Italian) because.. I like it that way.. and is in my home folder. PC # /home/gionata/Musica FolderB MUST be named "music", in my home folder on the NFS filesystem, NAS # /volume1/homes/gionata/music *because the synology media parse service only indexes the directory name music in the user home dirs!* (Damn Syno...) So I have different name on different system for the same folder! I could change the name on my home, do it in two runs or do some symlinks.. but I was just wondering if a more elegant solution could be found within rsync. Anyway I can login with ssh as many time I wantm with RSA key pair. Even multiplexing is not necessary, but thanks anyway for the info. I hope now the problem is more clear. Is not even a real problem.. :) *_______________Gionata Boccalini* 2015-06-08 22:18 GMT+02:00 Michael Johnson - MJ <mj at revmj.com>:> Thought I would chime in here.
