-### Scheduling a backup
-
-To schedule a cron job that backs up your repositories and GitLab metadata, use the root user:
-
-```
-sudo su -
-crontab -e
-```
-
-There, add the following line to schedule the backup for everyday at 2 AM:
-
-```
-0 2 * * * /opt/gitlab/bin/gitlab-rake gitlab:backup:create CRON=1
-```
-
-You may also want to set a limited lifetime for backups to prevent regular
-backups using all your disk space.  To do this add the following lines to
-`/etc/gitlab/gitlab.rb` and reconfigure:
-
-```
-# limit backup lifetime to 7 days - 604800 seconds
-gitlab_rails['backup_keep_time'] = 604800
-```
-
-NOTE: This cron job does not [backup your omnibus-gitlab configuration](#backup-and-restore-omnibus-gitlab-configuration) or [SSH host keys](https://superuser.com/questions/532040/copy-ssh-keys-from-one-server-to-another-server/532079#532079).
-
-### Restoring an application backup
-
-We will assume that you have installed GitLab from an omnibus package and run
-`sudo gitlab-ctl reconfigure` at least once.
-
-First make sure your backup tar file is in `/var/opt/gitlab/backups`.
-
-```shell
-sudo cp 1393513186_gitlab_backup.tar /var/opt/gitlab/backups/
-```
-
-Next, restore the backup by running the restore command. You need to specify the
-timestamp of the backup you are restoring.
-
-```shell
-# Stop processes that are connected to the database
-sudo gitlab-ctl stop unicorn
-sudo gitlab-ctl stop sidekiq
-
-# This command will overwrite the contents of your GitLab database!
-sudo gitlab-rake gitlab:backup:restore BACKUP=1393513186
-
-# Start GitLab
-sudo gitlab-ctl start
-
-# Create satellites
-sudo gitlab-rake gitlab:satellites:create
-
-# Check GitLab
-sudo gitlab-rake gitlab:check SANITIZE=true
-```
-
-If there is a GitLab version mismatch between your backup tar file and the installed
-version of GitLab, the restore command will abort with an error. Install a package for
-the [required version](https://www.gitlab.com/downloads/archives/) and try again.

 ## Invoking Rake tasks
 To invoke a GitLab Rake task, use `gitlab-rake` (for GitLab) or
