Script que ajuda a restaurar backups no GitLab, resolvendo problemas de permissões de arquivos no GitLab, entre outros (comandos obtidos da saída do comando ´sudo gitlab-rake gitlab:check SANITIZE=true` e http://doc.gitlab.com/ce/raketasks/backup_restore.html#omnibus-installations)

# Solution based in GitLab's official tutorial to restore backups:
# http://doc.gitlab.com/ce/raketasks/backup_restore.html#omnibus-installations
# (This script applies to GitLab installations from official .deb package!)
#
# To backup a GitLab repository server, simply run this command:
# 	sudo gitlab-rake gitlab:backup:create
# And copy the .tar file from /var/opt/gitlab/backups/ to the folder you want.

	# Reconfigure to avoid problems during restore backup
	sudo gitlab-ctl reconfigure

	# To ensure that GitLab is running before restore backup
	sudo gitlab-ctl start

	# Copy backup file to default GitLab's backups folder
	sudo cp "$1" /var/opt/gitlab/backups/

	# Giving reading permission to the file in backups folder
	sudo chmod +r /var/opt/gitlab/backups/"$1"

	# Stop the processes that are connected to the GitLab database
	sudo gitlab-ctl stop unicorn
	sudo gitlab-ctl stop sidekiq
	# Verify
	sudo gitlab-ctl status

	# Restart all GitLab processes after restoring backup
	sudo gitlab-ctl start

	# Fix permissions (`sudo gitlab-rake gitlab:check SANITIZE=true` suggestion)
	sudo chmod -R ug+rwX,o-rwx /var/opt/gitlab/git-data/repositories
