Server & desktop backup solutions
The first backup of the two options takes a while. The following ones are much faster, but it depends on how much you change. Only the changes are saved.
rsync
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.
Dependencies
The script needs inetutils
for hostname
command.
pacman -S inetutils
Credentials
echo "$password" > /etc/rsyncd.password chmod 400 /etc/rsyncd.password
Script
Add your details for DAEMONUSER=“”
and DAEMONHOST=“”
.
nano /root/rsnapbackup.sh

chmod +x /root/rsnapbackup.sh
Exclude folder and files
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/*
borg
Crontab
Follow our crontab tutorial first and add the following for your root user:
@daily /root/rsnapbackup.sh
@yearly
@annually
@monthly
@weekly
@daily
@hourly
@reboot
