The Relax-and-Recover documentation is being revised and updated.
This quick start guide will show you how to run Relax-and-Recover from the git checkout and create a bootable USB backup.
Start by cloning the Relax-and-Recover sources from Github:
git clone https://github.com/rear/rear.git
Move into the rear/ directory:
Prepare your USB media. Change /dev/sdb to the correct device in your situation. Relax-and-Recover will ‘own’ the device in this example.
This will destroy all data on that device.
sudo usr/sbin/rear format /dev/sdb
Relax-and-recover asks you to confirm that you want to format the device:
The device has been labeled REAR-000 by the ‘format’ workflow.
Now edit the ‘etc/rear/local.conf’ configuration file:
cat > etc/rear/local.conf <<EOF ### write the rescue initramfs to USB and update the USB bootloader OUTPUT=USB ### create a backup using the internal NETFS method, using 'tar' BACKUP=NETFS ### write both rescue image and backup to the device labeled REAR-000 BACKUP_URL=usb:///dev/disk/by-label/REAR-000 EOF
Now you are ready to create a rescue image. We want verbose output.
sudo usr/sbin/rear -v mkrescue
The output I get is:
Relax-and-Recover 1.13.0 / $Date$ Using log file: /home/jeroen/tmp/quickstart/rear/var/log/rear/rear-fireflash.log Creating disk layout Creating root filesystem layout WARNING: To login as root via ssh you need to setup an authorized_keys file in /root/.ssh Copying files and directories Copying binaries and libraries Copying kernel modules Creating initramfs Writing MBR to /dev/sdb Copying resulting files to usb location
You might want to check the log file for possible errors or see what Relax-and-Recover is doing.
Now reboot your system and try to boot from the USB device.
If that worked, you can dive into the advanced Relax-and-Recover options and start creating full backups. If you USB devices has enough space, initiate a backup using:
sudo usr/sbin/rear -v mkbackup
That is it. Your hard disk can now safely fail.
