The workaround is either to put as much of ssh_args as possible into $HOME/.ssh/config for the specific target host, or to create a /usr/local/bin/ssh-for-rsnapshot type script that incorporates the call to ssh with the relevant arguments.

Re: /usr/bin/ssh not found when rsync is executed within rsnapshot
There are 2 easy solutions: 1. put what you need to run in a script and specify --rsh=/path/script. 2. put your ssh options into your ~/.ssh/config file, and stop specifying --rsh. If you only want that key sometimes when going to that host, you can specify a host alias in the config. For instance: Host debx40-backup Hostname debx40 User backupuser IdentityFile /home/backupuser/.ssh/id_rsa That even lets you omit the backupuser@ prefix on the command, since you told ssh to use the right user, but only if you use debx40-backup:/ for the destination host. If you always want those options, just remove the -backup suffix (and the Hostname line) and they will get used for every ssh to debx40 (by name). that one really helped me out. Thanks a lot.

The error message is a bit misleading though. Make sure that there are no wrong whitespace characters in there. I've fallen into the trap of copypasting commands / configs from websites and having them fail mysteriously, until I noticed I could not left-shift those lines in vim with . Those leading spaces were not spaces but no-break spaces, hex value 0x80. So check your config / scripts with LANG=C cat -v /etc/rsnapshot etc. What could be the reason? How could i debug this? I often use strace -f -e execve command ... and / or strace -f -e execve command ... in such cases to see what it is really trying to run.

No, the later --rsh option overrides the weird v string, so that's not the issue. It appears to be that whatever compiled version of rsync he is using doesn't allow args -- it seems to be trying to find the command using the full string, including spaces and ssh options. Since normal rsync allows command args there, I don't know what is strange about his setup.

/usr/bin/ssh not found when rsync is executed within rsnapshot
Hello, yesterday i posted this issue on snapshot-disc...@listsourceforge.net (subject: wondering why backup wont start), but after reading the FAQ and searching the bugzilla DB i thought it could help to post here as well. i have a problem. But let me first describe my setup. i followed this howto: http://dev.kprod.net/?q=linux-backup-rsnapshot-no-root Now there is a backup server rpi-home and a remote host debx40. On both these computers there is debian jessie (with rsnapshot version 1.3.1) installed, there is a user backupuser and as far as i can see the remote login with password for that user works: backupuser@rpi-home ~ $ ssh debx40 -i ~/.ssh/id_rsa Linux debx40 3.12-1-486 #1 Debian 3.12.9-1 (2014-02-01) i686 ###some greeting lines### $ whoami backupuser here is the result of grep -v # /etc/rsnapshot | grep [a-z] i.e. the /etc/rsnapshot minus the comments and the empty lines: config_version 1.2 snapshot_root /media/extfp/Backup/rsnapshot/test/ no_create_root 1 cmd_cp /bin/cp cmd_rm /bin/rm cmd_rsync /usr/bin/rsync cmd_ssh /usr/bin/ssh cmd_logger /usr/bin/logger retain hourly 6 retain daily 7 retain weekly 4 verbose 5 loglevel5 logfile /var/log/rsnapshot.log lockfile/var/run/rsnapshot.pid rsync_long_args -ev --rsync-path=/home/backupuser/rsync-wrapper.sh ssh_args-i /home/backupuser/.ssh/id_rsa link_dest 0 rsync_numtries 1 backup backupuser@debx40:/ debx40/ and this is the content of /home/backupuser/rsync-wrapper.sh on the remote debx40. #!/bin/sh date /home/backupuser/backuplog echo $@ /home/backupuser/backuplog /usr/bin/sudo /usr/bin/rsync $@; in the /etc/sudoers there is a line backupuser ALL=NOPASSWD: /usr/bin/rsync when i enter e.g. sudo rsnapshot -D hourly on the backup server rpi-home i get this require Lchown Lchown module loaded successfully Setting locale to POSIX C echo 4702 /var/run/rsnapshot.pid mkdir -m 0755 -p /media/extfp/Backup/rsnapshot/test/hourly.0/ /usr/bin/rsync -av -ev --rsync-path=/home/backupuser/rsync-wrapper.sh \ --rsh=/usr/bin/ssh -i /home/backupuser/.ssh/id_rsa backupuser@debx40:/ \ /media/extfp/Backup/rsnapshot/test/hourly.0/debx40/ rsync: Failed to exec /usr/bin/ssh -i /home/backupuser/.ssh/id_rsa: No such file or directory (2) rsync error: error in IPC code (code 14) at pipe.c(85) [Receiver=3.1.0] rsync: connection unexpectedly closed (0 bytes received so far) [Receiver] rsync error: error in rsync protocol data stream (code 12) at io.c(226) [Receiver=3.1.0] rsnapshot encountered an error!
