::substitute exclude file above for <excludefile>, backup destination for <dest> and log file for <logfile> name<br />
:::e.g. <excludefile> /rsynch_exclude.txt<br />
::::<dest> /mnt/freecom/backups/bradnorRP1/<br />
::::<logfile> /backuplog_bradnorRP1.log<br />
<br />
:<tt>rsync -av --delete-delay --exclude-from=/<excludefile>.txt / <dest> >> /<logfile>.log</tt><br />
::or to preserve hard links and keep remote mirror of rsnapshot<br />
:<tt>rsync -aHv --delete-delay --numeric-ids --exclude-from=/<excludefile>.txt / <dest> >> /<logfile>.log</tt><br />
<br />
;to another server<br />
:create a key for root which does not require a password<br />
::<tt>$ ssh-keygen -t rsa</tt><br />
:::and specify a filename for the key but no password<br />
:set up key-based authentication for ssh on target server<br />
::create user on target server which accepts root's key for authentication<br />
::copy the file to the server you wish to authenticate to and add the public key you created to the <tt>~/.ssh/authorized_keys</tt> file of the target user<br />
:use rsync to copy files, e.g.<br />
:::<tt>sudo rsync -aHv --delete-delay --numeric-ids /var/lib/rsnapshot rpbackup@192.168.192.203:/rpbackups/RP1-rsnapshot</tt></div>Ch
