jumpaku/backup-with-nextcloud repository overview

⁠backup-with-nextcloud

Docker image to backup files with remote nextcloud.

⁠Introduction

• It synchronizes the files to be backed up with your nextcloud server.
• It can prepare the files to be backed up by executing the specified script.
• It repeats these processes with cron.

⁠Volumes

⁠/backup/

This container synchronizes files in a directory named /backup/ with a remote nextcloud. Mount the host directory containing the files to be backed up to /backup/ of this container.

⁠/backup.sh

This container can execute a complex process to prepare the files to be backed up. If you want to execute the complex process, create a script that places the files to be backed up to /backup/ and mount the script as backup.sh to /.

If backup.sh is not mounted, the following script is generated by default.

#!/bin/bash

⁠Environments

From the following environments:

    environment: 
      - "CRON_EXP=0  *  *  *  *"
      - "CRON_USER=root"
      - "NC_URL=http://nextcloud/remote.php/webdav/"
      - "NC_USER=nc_user"
      - "NC_PASSWORD=nc_password"

the following /etc/crontab is generated.

0  *  *  *  * root /backup.sh && nextcloudcmd --user nc_user --password nc_password /backup/ http://nextcloud/remote.php/webdav/
