Configuring server

Before use you need to install and configure FTP (proftpd recomended) and TFTP (tftpd recomended) server.

We DO NOT recomend to use vsftpd!

# installing proftpd server
sudo apt-get install proftpd
# enabling and starting proftpd server
sudo systemctl start proftpd
sudo systemctl enable proftpd

# installing tftp server
sudo apt install tftpd-hpa 
# enabling and starting tftp server (variant 1)
sudo systemctl start tftpd
sudo systemctl enable tftpd
# I same case previous commands can be broken. Use next one
# enabling and starting tftp server (variant 2)
sudo systemctl start tftpd-hpa
sudo systemctl enable tftpd-hpa

The root folder of both servers must be the same!

Next step set up backup server ip, login and password in Grusher settings. Do backup

Default TFTPD config

sudo nano /etc/default/tftpd-hpa

TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/home/backup/backup"
TFTP_ADDRESS="0.0.0.0:69"
TFTP_OPTIONS="--secure --create"

If you are using /home directory do next:

sudo systemctl edit tftpd-hpa.service

And insert 

[Service]
ProtectHome=false
ReadWritePaths=/home/backup/backup

Reload daemon and service

sudo systemctl daemon-reload
sudo systemctl restart tftpd-hpa

---

 

Default ProFTPD config

# Use this to jail all users in their homes
DefaultRoot /home/backup/backup

Fix for Ubuntu 26.04 (if backup is not working)

sudo find /etc/apparmor.d/ -iname "*proftpd*"

Edit proftpd ot other file showed after find

sudo nano /etc/apparmor.d/proftpd

Add the permissions for the required operations for your directory tree, for example:

/home/backup/backup/** rwk,

_{* rwk - read, write, lock; rename requires permissions on the file itself and on the parent directory with w}

Then reload the profile:

sudo apparmor_parser -r /etc/apparmor.d/proftpd
