This repository contains a Bash script for backup Nextcloud data and its database using BorgBackup.
- A running Nextcloud server
- Root access to the server
Create the required directories for backup and restoration:
mkdir -p /backup/data /backup/temp /restore
Install BorgBackup using the following command:
apt install -y borgbackup
Initialize the Borg repository:
borg init -e repokey-blake2 /backup/data/
Copy the backup script backup.sh to the /root/borgbackup/ directory and make it executable:
nano /root/borgbackup/backup.sh # Paste the script content here
chmod +x /root/borgbackup/backup.sh
Fill the .env file with the appropriate configuration variables
nano /root/borgbackup/.env
Ensure that the permissions of the .env file are restricted to prevent unauthorized access. You can set the file permissions using:
chmod 600 /root/borgbackup/.env
Add a cron job to run the script automatically. For example, to start the backup daily at 03:00:
crontab -e
Add the following line:
0 3 * * * /root/borgbackup/backup.sh > /dev/null 2>&1 # This suppresses any output and error messages
To list existing backups, use:
borg list /backup/data
To mount a backup and browse its content:
borg mount /backup/data::<date> /restore/
Example:
borg mount /backup/data::20230707_070011 /restore/
To unmount the backup:
borg umount /restore
