8.2. Performing a Full Backup of Satellite Server or Capsule Server

Red Hat Satellite 6.8 uses the satellite-maintain backup command to make backups.

There are three main methods of backing up Satellite Server:

  • Offline backup
  • Online backup

  • Snapshot backups

    For more information about each of these methods, you can view the usage statements for each backup method.

For offline backups: 

# satellite-maintain backup offline --help

For online backups: 

# satellite-maintain backup online --help

For snapshots backups: 

# satellite-maintain backup snapshot --help

Directory creation

The satellite-maintain backup command creates a time-stamped subdirectory in the backup directory that you specify. The satellite-maintain backup command does not overwrite backups, therefore you must select the correct directory or subdirectory when restoring from a backup or an incremental backup. The satellite-maintain backup command stops and restarts services as required.

When you run the satellite-maintain backup offline command, the following default backup directories are created:

  • satellite-backup on Satellite
  • foreman-proxy-backup on Capsule

If you want to set a custom directory name, add the --preserve-directory option and add a directory name. The backup is then stored in the directory you provide in the command line. If you use the --preserve-directory option, no data is removed if the backup fails.

Note that if you use a local PgSQL database, the postgres user requires write access to the backup directory.

Remote databases

You can use the satellite-maintain backup command to back up remote databases.

You can use both online and offline methods to back up remote databases, but if you use offline methods, such as snapshot, the satellite-maintain backup command performs a database dump.

Prerequisites

Procedure

To perform a full offline backup of Satellite Server or Capsule Server, complete one of the following steps:

警告

Request other users of Satellite Server or Capsule Server to save any changes and warn them that Satellite services are unavailable for the duration of the backup. Ensure no other tasks are scheduled for the same time as the backup.

  • On Satellite Server, enter the following command: 

    # satellite-maintain backup offline /var/satellite-backup

  • On Capsule Server, enter the following command: 

    # satellite-maintain backup offline /var/foreman-proxy-backup
