NextCloudPi Nc-backup did not create backups in External HDD + Raspi 4 + Kubuntu 64

[BeGo]

I am currently searching for why my Nextcloud backup folder empty, while the nc-backup reporting successful backup. I see the zip being compiled as bak, but the file just vanish after the backup proces finished.

Environment

• RaspBerry Pi 4 + External HDD 1 TB

• fstab UUID=[my UUID] /media/[username]/MyData ext4 rw,suid,dev,auto,user,async,exec 0 2, following this tutorial, https://askubuntu.com/questions/678857/fstab-doesnt-mount-with-exec. I chmod owner to $USER

• Ubuntu Server 18.04 + Kubuntu Desktop, taken from https://github.com/TheRemote/Ubuntu-Server-raspi4-unofficial, because I need the raspi-config which is missing from the official

• Snap Docker, https://snapcraft.io/docker, which recently “revived from the coma”, https://forum.snapcraft.io/t/the-future-of-the-docker-snap/7218/9

• NextCloudPi Docker, using Docker Compose from https://ownyourbits.com/2017/11/15/nextcloudpi-dockers-for-x86-and-arm/ and https://docs.nextcloudpi.com/en/how-to-get-started-with-ncp-docker/.

• media/[username]/MyData/NextCloudPi/Data:data

• Manual port forward, LetsEncrypt, etc feature in NextCloud site working

• All feature in nextcloud.mysite.ext:4443 working except backup, which report success bus the backup folder empty, and nextcloud update, which shall fail if I am deliberately upgrade from 16 to 18 to test the rollback and the rollback fail.

what is the backup location you are using in nc-backup

[BeGo]

Basically, in the next folder from the Nextcloudpi data, inside the external HDD.

media/[username]/MyData/NextCloudPi/Backup

My compose.yml look like this
version: ‘3’
services:
nextcloudpi:
image: ownyourbits/nextcloudpi-armhf
restart: always
command: “${IP}”
ports:
- “80:80”
- “443:443”
- “4443:4443”
volumes:
- /media/[username]/MyData/NextCloudPi/Data:/data
- /etc/localtime:/etc/localtime:ro
container_name: nextcloudpi

@BeGo

media/[username]/MyData/NextCloudPi/Backup

I’ d try, adding the Backup location to your volumes

@BeGo

volumes:

• /media/[username]/MyData/NextCloudPi/Data:/data
• /etc/localtime:/etc/localtime:ro

• /media/[username]/MyData/NextCloudPi/Backups:/backups

Docker can not navigate outside it’s container otherwise.

[BeGo]

I just tried after reading your post.

I stop rm revise compose.yml and compose up again according to your suggestion.

now the response is slightly different, the backup start by calculating space size.

the whole process run like normal, but the backup folder still empty.
