 This second backup tool is to be used regularly to backup your Home directory (for example the /C/Users/YourUsername directory in windows, or the /home/yourusername on linux), as well as any file folder that is not your installed programs (like an extra disk used only to store files, videos, etc.), and can also be used to backups smaller folders.
-It is called [[https://restic.net/|Restic]]. Contrary to CloneZilla, you do not need to turn off the computer to make the backup, which makes CloneZilla a bit cumbersome to use on a daily basis. It is also incremental: if you make several snapshots, only the difference since the last snapshot will actually be saved. This makes it extremely lightweight and fast (once a snapshot already exists).

 ==== Initialisation of the backup folder ====
-make a directory for the backup location. The open a terminal and enter:
+More detailed infos can be fond [[https://restic.readthedocs.io/en/stable/030_preparing_a_new_repo.html|here]].
-<code> restic -r /path/to/your/backup/directory init </code>
+Make a directory for the backup location. The open a terminal and enter:
-Once this is done, you can do another backup of your /home, which contains all your regular files. For this you can use the software backintime. You can install it with:
+<code> restic init --repo /path/to/your/backup/directory </code>
-<code>
-sudo apt install backintime-qt
-</code>
+You will be asked a password. You should choose a strong password, either directly generated from [[diceware|the diceware method]] or randomly generated by a password manager that is locked by a password generated by [[diceware|the diceware method]].
-Before launching it, we need to decrypt the encrypted disk, and mount the logical volume we intend to use:
+==== Do the actual backup ====
-<code>
-sudo cryptsetup luksOpen /dev/sdb2 cryptsetup
-sudo vgchange -ay
-sudo mount /dev/mapper/vgbackup-home /mnt
-</code>
-now everything written on /mnt on your computer will be written on your disk.
+open a terminal and enter:
-You can then launch backintime with:
+<code> restic -r /path/to/your/backup/directory --verbose backup /path/to/the/folder/you/want/to/backup </code>
-<code>
-sudo backintime-qt
-</code>
-you can then configure it to save things in /mnt:
+you will be asked for your password and informed about the process. If it is the first snapshot of a big folder, it can take a bit of time.

+More infos can be found [[https://restic.readthedocs.io/en/stable/050_restore.html|here]].
+First, you can see the existing snapshots in your backup folder by entering:
-{{ ::backintime_3.png?600 |}}
+<code> restic -r /path/to/your/backup/folder snapshots </code>
-And then click on "Take snapshot" and wait for it to finish:
