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

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

----------------------------------------------------------------------------
rsnapshot encountered an error! The program was invoked with these options:
/usr/bin/rsnapshot -D hourly
----------------------------------------------------------------------------
ERROR: /usr/bin/rsync returned 12 while processing backupuser@debx40:/
/usr/bin/logger -i -p user.err -t rsnapshot /usr/bin/rsnapshot -D hourly: \

/usr/bin/logger -i -p user.err -t rsnapshot /usr/bin/rsnapshot -D hourly: \
ERROR: /usr/bin/rsnapshot -D hourly: completed, but with some errors
I suppose the important info is in that line
rsync: Failed to exec /usr/bin/ssh -i /home/backupuser/.ssh/id_rsa: No such
file or directory (2)
but surprisingly to me: the Backup starts when i do
sudo /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/
, which is the exact same command (copy-pasted from the rsnapshot output) that
caused the error
in the first place. Except the sudo in front of it.
What could be the reason? How could i debug this?
