Configuration Management

VyOS comes with an integrated versioning system for the system configuration. The configurations are versioned locally for rollback but they can also be stored on a remote host for archiving/backup reasons.

set system config-management commit-revisions <number>
Change the number of commit revisions to <number>, the default setting for this value is to store 20 revisions locally.
set system config-management commit-archive location <url>

If you want to save all config changes to a remote destination. Set the commit-archive location. Every time a commit is successfully the config.boot file will be copied to the defined destination(s). The filename used on the remote host used will be: config.boot-hostname.YYYYMMDD_HHMMSS

Destinations will be configured as any of the below URI

  • scp://<user>:<passwd>@<host>/<dir>
  • sftp://<user>:<passwd>@<host>/<dir>
  • ftp://<user>:<passwd>@<host>/<dir>
  • tftp://<host>/<dir>


The number of revisions don’t effect the commit-archive.
