I have been doing this in one shape or form for a long time. It is running right now, copying all the sub dirs and creating any new needed with: rsync -ah --stats --delete -e "ssh -pnnnn -l user" /var/flexshare/shares/ nevia.htt-consult.com:/media/WD3TB01/backups/homebase/var/flexshare/shares Note the source ending with / That is needed.?

But since it is executing ssh under the hood, and ssh *does* pay attention to that file, it takes effect. If you?re creating that file for the first time, be sure to chmod 600 it. Ssh will ignore it if it?s not locked-down. RTFM for details.>>> /var/flexshare/shares x.htt-consult.com:/media/backup/homebase/var/flexshare/shares/ >> Rsync won?t create multiple levels of directories on the target.

I have been doing this in one shape or form for a long time.Let me clarify: If only /media/backup exists on the remote machine, I believe you?ll end up with /media/backup/shares with that command. If at least /media/backup/homebase/var/flexshare exists, rsync will always create ?shares? under ?flexshare" on the remote host. Anything below that level will also be created, regardless of depth. I?m speaking only of the target path given as the last argument to rsync here, not of the source machine?s directories discovered during the sync process. It?s possible this behavior changed since I last looked at it. I ran into this issue many years ago and now ensure that the target path passed to the rsync command exists on the remote host before starting the sync.
Warren, Thanks!

I ran into this issue many years ago and now ensure that the target path passed to the rsync command exists on the remote host before starting the sync.Always a challenge to get this right and get the right behavior.? I use rsync for backing up my data from my notebook to a USB drive. Also when I was active in IEEE 802, at the meetings I could rsync all the documents off the local server.? The public server does not support rsync.? Plus I rsync all the IETF RFCs and drafts every night. So I have a lot of old habits.

With only ~/tmp existing on the target machine, this command: $ rsync -a path/to/stuff remote-host:tmp/foo/bar gives: rsync: mkdir "/home/USER/tmp/foo/bar" failed: No such file or directory (2) rsync error: error in file IO (code 11) at main.c(657) [Receiver=3.1.2] I recall a confusing, softer failure mode, so perhaps they decided this would be better handled with a hard failure to avoid some end user confusion. (And probably some support email traffic!) The trailing slash on the source path affects the remote result once you get past this issue, but adding a slash doesn?t prevent the error in this condition.
Warren, Just want to say thanks.? I have my automated backups going now. Good old cronie. Since I have a cat6 line to my neighbor (as a favor for their net access), I only have to move the backup box to his house and I have off-site backups for $150 outlay (arm SOC and 4 TB drive) and <$50/yr electric (our rate is ~$0.21/KWH).? You can't buy cloud storage for that price.
