Hello, I am running yunohost on a rpi4 and would like to set automatic back-ups on a mounted SSD, I tried with borg, but I am not sure how to use it. Also archivist seems a good idea, but the app is not maintained anymore.
On borg I am confused ofwhat to put on repository under panel configuration. The device I want to make the back-ups is filesystem /dev/sda1 and mounted on /media/storage.
Please let me know if borg is the best solutino for it.
Borg is actually in two apps: a Borg Client for your server to backup and an external Borg Server which will receive the backups.
Some documentation:
Try it out. There is no dedicated maintainer at the moment, but the Apps group tries to keep it alive. I am quite satisfied with it. (documentation)
I tried archivist, but keeps getting an error:
Errore: "500" Internal Server Error
Azione: "GET" /yunohost/api/apps/archivist/config-panel?full&locale=it
Messaggio d’errore:
Config panel question ‘encrypt’ should be initialized with a value during install or upgrade.
Another option is restic if you want a more DIY solution
- install restic
- make repo on backup drive
- setup cron script to take snapshots (de-duplicated like borg)
I don’t fully understand that, could you help with what was done on that post to solve this problem?
- Mount your disk (ext4) on /media/storage and change your /etc/fstab to make it mounted at boot
- Install borg and answer /media/storage/backup to the repository question
- Wait for the first backup (depending of the frequencies you choose) OR run by hand
yunohost backup create --system conf_ldap --methods borg_app - You should have a green success alert on top of the config panel in side Apps > Borg > Config Panel (in the webadmin)

Oh thanks for the help, it’s different isntalling from webadmin and terminal, only on terminal I got those options. Installing now.
I have another question, I have a 128GB pendrive for backups, but also a SSD being used for nextcloud. Can I run the backup on both drives?
Running the above command gave me this output:
Warning: Failed to format translated string ‘backup_applying_method_custom’: ‘Calling the custom backup method ‘{method}’…’ with arguments ‘()’ and '{}, raising error: KeyError(‘method’) (don’t panic this is just a warning)

You could do it in private if you prefer.
So your error in the log is “There is already something at /media/backup”
You probably should indicate during the install of borg app /media/backup/backup instead (or something like that). The dir /media/backup/backup should be empty before the repo was initialized.
But even after that I still get errors:
yunohost backup create --system conf_ldap --methods borg_app

Info: The archive will contain about 119.7KiB of data.

Success! Backup created

This appeared after running the command for the second time:
Warning: A repository already exists at /media/storage/backup.
It looks like and must delete the backup folder uninstall and reinstall borg.
Warning: Failed to format translated string
Warning: A repository already exists at
Those warnings are not errors, but warnings, so your backup is successfull here (but just for ldap conf)
I believe your setup is ok, wait tomorrow to see if the backup archive are listed in your borg repository.
I ran the command three times, now I have three borg repositories. I mistakenly thought the command was to create a backup, but it’s to create a backup repo, right?
No yunohost backup create creates a backup archive (and it creates the repo if needed). If the repo already exists it doesn’t recreate it (if you don’t change the address of the repo).
Strange the backup archive has only a few kb, it should be around 12GB
Its because i said you to run yunohost backup create --system conf_ldap --methods borg_app so it’s just a backup of the ldap db.
That’s why i said you to wait the true backup you planned during the installation.
But if you want to know more quicly, you can run yunohost backup create --methods borg_app
Oh thank you for the explanation, I tried, it works!
