Using rsynch

⇐ Backup

Using rsynch

create exclude file

exclude file lists directories to exclude from backup

suggested list

/proc/*

/sys/*

/dev/*

/boot/*

/tmp/*

/run/*

/mnt/*

/media/*

run or cron

substitute exclude file above for <excludefile>, backup destination for <dest> and log file for <logfile> name

e.g. <excludefile> /rsynch_exclude.txt

<dest> /mnt/freecom/backups/bradnorRP1/

<logfile> /backuplog_bradnorRP1.log

rsync -av --delete-delay --exclude-from=/<excludefile>.txt / <dest> >> /<logfile>.log

or to preserve hard links and keep remote mirror of rsnapshot

rsync -aHv --delete-delay --numeric-ids --exclude-from=/<excludefile>.txt / <dest> >> /<logfile>.log

to another server

create a key for root which does not require a password

$ ssh-keygen -t rsa

and specify a filename for the key but no password

set up key-based authentication for ssh on target server

create user on target server which accepts root's key for authentication

copy the file to the server you wish to authenticate to and add the public key you created to the ~/.ssh/authorized_keys file of the target user

use rsync to copy files, e.g.

sudo rsync -aHv --delete-delay --numeric-ids /var/lib/rsnapshot rpbackup@192.168.192.203:/rpbackups/RP1-rsnapshot
