Server & desktop backup solutions

This is an old revision of the document!

Follow our rsync tutorial first.

The snapshots are stored locally and remotely via rsync daemon.

This backup solution is only recommended for an internal network. Use an encrypted backup method with borg instead.

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

Server

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

Exclude folder and files

This is an example and widely used as a starting point for a server. Add anything you don't need to backup.

backup-filter.rule

/dev/*
/proc/*
/sys/*
/tmp/*
/run/*
/mnt/*
/media/*
/home/*
/root/backup/*
/lost+found
