restic-backup

tl;dr

sudo su
curl -s https://raw.githubusercontent.com/Momro/restic-backup/refs/heads/main/install.sh | bash

You will have to install the cron tab manually, though.

The long way

First, we need restic as backup program

sudo apt update && sudo apt upgrade -y && sudo apt install restic cifs-utils -y

Then create folders:

sudo su
mkdir /root/restic
mkdir /root/smbcred
mkdir /mnt/restic-backup-target
mkdir /mnt/restic-restore

Either clone my config files or create new ones

clone

git clone https://github.com/Momro/restic-backup /tmp/restic
mv /tmp/restic/backup.sh /root/restic/.
mv /tmp/restic/exclude.txt /root/restic/.
mv /tmp/restic/include.txt /root/restic/.

create

# touch backup.sh
# touch exclude.txt
# touch include.txt

replace password

Replace your restic password in the config

cd /root/restic
echo "Enter Restic repo password "
read -p "" RESTICPASSWORD
echo
sed -i "s|enter your password here|${RESTICPASSWORD}|g" backup.sh

add password to smbcred

touch /root/smbcred/backup
echo "username=backup" >> /root/smbcred/backup ; echo "password=" >> /root/smbcred/backup

Adjust include/exclude

Note: If you exclude /mnt and include /mnt/some-folder, it will be excluded.

set your home folder

echo "/home/<home folder>" >> include.txt

Finally, set up a cron tab that mounts your backup share. Must be run as root!

sudo apt install cron
sudo su
crontab -e

@reboot sleep 60 && mount -t cifs //qnap/backup/<device name> /mnt/restic-backup-target -o credentials=/root/smbcred/backup,uid=1000,gid=1000,file_mode=0775,dir_mode=0775,noperm,forceuid,forcegid,vers=3.0
0 3 * * * /root/restic/backup.sh do-backup && /root/restic/backup.sh do-forget

initialize

restic -r <backup location> init
enter secure password twice

backup

sudo su
cd
cd restic
./backup.sh do-backup

restore

sudo su
cd /root/restic
screen -S mount
./backup.sh do-mount
<ctrl+a d>
cd mount/snapshots/latest
<do your thing>
screen -r mount
<ctrl+c>
exit
