Make a repository copy to the GitLab home directory.

cd /home/git
git clone https://github.com/pquerner/gitlab-backup-uploader.git

I recommend using this uploader via git clone instead of downloading, so you can benefit from automatic update scripts.

Download and install the Google Drive CLI for your system. This has been tested with version 2.1.0 Linux x64 (Ubuntu).

wget https://docs.google.com/uc?id=0B3X9GlR6EmbnQ0FtZmJJUXEyRTA -O drive
chmod a+x drive
sudo mv /home/git/drive /usr/bin/

Run Google Drive CLI and configure it with your Google Account Drive that will receive the files. When running, follow the instructions that appear on the terminal.

drive

After configuring the Google Drive CLI, create a directory in Google Drive, and get his ID. Example: if the URL of the directory on Google Drive is this:

https://drive.google.com/drive/u/0/#folders/0B43Qn3ksX-mMRzl1S05mbDNIdGc

the directory ID is the part that is left after /#folders/. In other words:

0B43Qn3ksX-mMRzl1S05mbDNIdGc

With ID in hand, register it in the configuration file. How to do that?

Make a copy of the example configuration file:

cd /home/git/gitlab-backup-uploader/conf
cp upload.cfg.example upload.cfg

Edit upload.cfg, and change the following items:

• The parameter GITLAB_BACKUPS with the full path of the GitLab backup directory.
• The parameter GDRIVE_DIRECTORY_ID with the Google Drive directory ID that will receive the backup files.
• The parameter UPLOAD_COMPRESS_FILE to decide whether the backup will be compressed prior to upload.
• The parameter ENCRYPT_FILE to decide whether the backup will be encrypted prior to upload.
• The parameter ENCRYPT_PASSWORD_FILE to the file which holds the private password for GPG to use (plaintext). Keep this file safe!

Then just put the upload script in crontab (com crontab -e):

# Upload the latest GitLab backup to Google Drive at 10pm.
0 22 * * * /home/git/gitlab-backup-uploader/gitlab-backup-upload.sh 1> /home/git/gitlab-backup-uploader/log/cron.log 2>&1

The shell script "gitlab-backup-upload" accepts the following optional parameters:

-c = Configuration file to use. Defaults to /conf/upload.cfg
Reason:
    If you save your /etc/gitlab directory from a cronjob for instance, you can save it with this script also.
    (Example cronjob : tar cfz /var/opt/gitlab/backups/opt/$(date "+opt-gitlab-%s.tgz") -C / opt/gitlab)
-d = Dry-run mode. Does not actually do anything but shows what would be done. Good for testing.
-k = Keep old uploaded file. Normally this script deletes the last uploaded file uploaded to your GDrive account. This parameters prevents that action.

Check if any new configuration variables exists in conf/upload.cfg.exmaple and if there is, add them to your existing configuration file.

#####initial to "v0.1.12" refer to git log

#####"v0.1.12" to "v0.1.13" Added GPG encryption of backup file.
This version added a new configuration variable to the configuration file
