Server & desktop backup solutions

Follow our rsync tutorial first.

The snapshots are stored locally and remotely via rsync daemon.

The script needs inetutils for hostname command.

pacman -S inetutils

echo "$password" > /etc/rsyncd.password
chmod 400 /etc/rsyncd.password

Add your details for DAEMONUSER=“” and DAEMONHOST=“”.

nano /root/rsnapbackup.sh

#!/bin/sh

## Based on:
## my own rsync-based snapshot-style backup procedure

# sync

rsync $OPTS $EXCL $SRC $SNAP/latest >> $SNAP/rsync.log

# make a hardlinked copy named as the date

COUNT=$( wc -l $SNAP/rsync.log|cut -d" " -f1 )
if [ $COUNT -gt $MINCHANGES ] ; then
        DATETAG=$(date +%Y-%m-%d-%H:%M)
        if [ ! -e $SNAP/$DATETAG ] ; then
                cp -al $SNAP/latest $SNAP/$DATETAG
                chmod u+w $SNAP/$DATETAG
                mv $SNAP/rsync.log $SNAP/$DATETAG
               chmod u-w $SNAP/$DATETAG
         fi
fi

rsync -avAXHP --delete --password-file=/etc/rsyncd.password $SNAP rsync://$DAEMONUSER@$DAEMONHOST/archive/backup/$HOSTNAME

chmod +x /root/rsnapbackup.sh

This is an example. Add anything you don't need to backup. And change home $USER.

nano /root/backup-filter.rule

/dev/*
/proc/*
/sys/*
/tmp/*
/run/*
/mnt/*
/media/*
/lost+found
# root user
/root/backup/*
/root/.cache/*
# Home user
/home/$USER/.cache/*
