Source: LVM over SSH

Creates an LVM snapshot on a remote host via SSH.

Module: backups.sources.lvmssh

Example

{
  "id": "mydisk1",
  "type": "lvm-ssh",
  "name": "My LVM Volume",
  "sshhost": "hostname.domain.com",
  "sshuser": "root",
  "vg_name": "ubuntu-vg",
  "lv_name": "mydisk1",
  "size": "5G",
  "retain_snapshots": 3
}

Parameters

Key Required Purpose
id Yes Unique identifier for this source.
name No Description for reporting (defaults to id).
sshhost Yes Remote hostname to SSH to.
sshuser Yes SSH username (typically root for LVM access).
vg_name Yes LVM volume group name.
lv_name Yes LVM logical volume name.
size Yes Size of the snapshot volume (e.g. 5G).
