It would be handy to be able to schedule hot backups to go to a NAS.. So we saw in the previous paragraphs how to save some files on a Raspberry PiNow, how to do if you have a complex installation that you want to fully back up? The good practice is to name the file with the current date time, like this: Nothing changed except we add the date in the DEST_FILE variable and we stop deleting the previous backup, Each time the script run, it will now create a new file and keep all the previous versions, Once we have created our script, following the previous steps, most of the work is done, It remains only to program our script so that it starts every day for exampleFor that, we will use the crontab, This cron will run your backup script each day at midnight, but you can change it if you want, If you backup files with privilege access needed, don’t forget to schedule the script in the root crontab (sudo crontab -e), If you are not comfortable with this, do not hesitate to read my tutorial on scheduling tasks on Raspberry Pi, As you can see, each day a new file will be created and we never delete itWhat you do to free space is to delete files older than eight days (or more if needed). The ultimate guide to backup and restore your Raspberry Pi. Save my name and email in this browser for the next time I comment.

No way to use rpi-clone to backup straight to an image file on a mounted volume? Vous savez maintenant comme réaliser des sauvegardes de votre Raspberry Pi de plusieurs manières, Essayez de les programmer ou en tout cas de les faire régulièrementSans oublier de les vérifier de temps en temps, Il n’y a rien de pire qu’une sauvegarde qui ne s’est pas lancée depuis des mois, ou que l’on est incapable de récupérer, car le test n’a jamais été fait , Tenez vous informés des dernières nouveautés en vous inscrivant ici. So now you should be able to put the rsync command in a script that will not ask for a passwordThe script should look like this: Then schedule the script by adding it in your crontab as explain previously, If your computer is on Windows, you can also send your backup to it, manually or automatically, To manually transfer files from the Raspberry Pi to your Windows computer, the easiest way is to install WinSCP on WindowsIt’s a free software to transfer files with SSH, There is no way to schedule a transfer with WinSCP.

L’utilisation du logiciel est très intuitive : N’hésitez pas à démarrer ensuite cette carte SD sur un autre Raspberry Pi identique si vous en avez la possibilité, afin de vous assurer que cela fonctionne, Si vous êtes sur Raspbian Lite ou si vous préférez utiliser un script pour pouvoir l’automatiser, voici comme faire via un script disponible sur Internet, Je vais vous expliquer ici comment utiliser ce scriptMais vous trouverez toutes les informations complémentaires sur la page GitHub du projet, Et voilà! I'm the lead author and owner of RaspberryTips.com. Start by downloading and installing the script: Then use fdisk to get the backup SD card name. Depuis le Raspberry Pi, ajoutez ce fichier dans vos clés autorisées : Essayez maintenant de vous connecter depuis l’ordinateur, cela ne devrait plus demander de mot de passe : Ajoutez un nouveau site avec les informations du Raspberry Pi : Sur la droite, vous verrez les fichiers du Raspberry Pi, et sur la gauche, ceux du PC, Vous pouvez bien sur supprimer les vieux fichiers présents sur votre ordinateur pour ne garder que les plus récents, Créez un nouveau dossier qui accueillera vos sauvegardes, Faites un clic droit sur ce dossier et choisissez Propriétés dans le menu, Rendez-vous dans l’onglet Partage et cliquez sur Partager, Par défaut, l’utilisateur de l’ordinateur aura accès à ce partage, mais vous pouvez ajouter d’autres utilisateurs si vous voulez, Une fois que tout est prêt, cliquez sur le bouton Partager, C’est bon, vous partagez maintenant ce dossier sur le réseau local, Créez un dossier qui servira de point de connexion, Transférer les fichiers sur un autre appareil, Importer la sauvegarde dans une base avec un nom différent, puis copier uniquement ce qui est nécessaire dans la base qui a un problème, Ou renommer la base corrompue, la recréer (vide) et ensuite importe le fichier, Éteignez le Raspberry Pi et récupérez la carte SD.

Test the weekly backup using the week number : You’re done. Pour transférer manuellement les fichiers du Raspberry Pi vers Windows, la méthode la plus simple sera d’installer le logiciel WinSCP sur WindowsC’est un logiciel gratuit pour transférer des fichiers via SSH : Si vous souhaitez automatiser cela, WinSCP ne sera pas la solutionEt installer SSH sur Windows n’est vraiment pas pratiqueIl nous faut donc trouver un autre moyenCe que je vous propose, c’est de partager un dossier sur Windows, et de laisser le Raspberry Pi gérer l’automatisation de la copie. Je suis l'auteur principal et le créateur de RaspberryTips. Now that the share is available, you can create and schedule a script to copy backup files to this folder each day for example: This backup is the easiest one to restoreYou only need to extract files from the archive and send them back to the original folder, On Linux, you can use the default archive software from your distributionFor example, on Ubuntu, double-click on the backup file to open it and see files in itAnd then click “Extract”, Once you get the needed files, send them back to the Raspberry Pi with rsync as seen above, On Windows, I’m not sure that the default tool can open a .tar.gz file, but you can tryIf not you have to install a software like 7zip or WinRAR, Uncompress the files with this tool and transfer them to the Raspberry Pi with WinSCP as seen above, It’s a good idea to follow this restore procedure at least onceSo you can be sure that it works and that you know how to do it, With this method, it’s easy to check that your backup is well done each day as expected. 2.1 Files selection First, let’s create a file that lists all the files that we want to backup : Salut à tous ! The first method you can use if you have a simple installation is to backup only the needed filesFor example, if you use your Raspberry Pi for a security camera, once you back up the configuration file, it’s ok, you don’t need moreSo we’ll see step by step : Before starting to create the script, you have to identify the files you need to saveIn my script I’ll use a file and a folder that you can adapt to your needs: Then we need to create a backup folder to store the files, And finally, the first script could look like this, As you can see it’s a basic script, that will overwrite the old backup each timeSo now we’ll improve this script on several points, The first good practice we’ll use to improve the scripts is to add variablesFor example, you have 200 files to backups to /home/pi/backups and tomorrow you want to save them in /media/nas/pi/You’ll have to edit 200 lines in your script to change the destination folderA better way to do this is to create a variable at the beginning with the destination folder path and use it for each lineI’ll also do the same for the “cp” command, so if you want to change it to use rsync or another command, you’ll have only one line to edit, The result will be the same but it will be easier to update, Most of the time, we use compression for backup or at least archive filesI’ll use tar to archive all files in one and gzip to compress this file, I add a new variable DEST_FILE to store the file name of the backup“tar -rvf” allows you to append several files to one tar file“gzip” allows you to compress the whole tar file, As you can see in the last script, we delete the previous backup each timeIt’s not a good thing to do.
