edit, tabs instead of spaces
- use tabs where the other lines indicate they use tab, spaces will not work
- if you use vim to edit rsnapshot.conf, put the following into your .exrc
:autocmd BufRead rsnapshot.conf set noexpandtab
or use
set list set noexpandtab
and then use "tab" instead of "space" where you see tabs (^I).
ssh backup of remote sites
- enable ssh at all
cmd_ssh /usr/bin/ssh
- set the parameters if you really need to, prefer ~/.ssh/config
ssh_args -o BatchMode=yes -p 22
- create an entry for the backup like
backup root@your-remote-host-in-config-via-ssh-key:/etc/ your-remote-host/
- install rsync at the remote host
apt-get install rsync
check
- check the config from the shell
