Snapshots copy the entire VM including configurations and applications, creating large files that require storage in your environment. Over time, snapshots can overwhelm servers or take up space best used by active processes.

You can manage snapshots using AppStack, the VM Details page, or with the sprawl dashboard. To manage VMs that are losing capacity to snapshots, SolarWinds recommends using the Sprawl dashboard.

The following example shows you have to determine if any snapshots need to be removed from your database backup VM. Reducing these snapshots provides additional capacity for automated database backups:

Prior to deleting the snapshot, verify if the snapshot should be deleted or stored. When deleted, the snapshot cannot be recovered.

  1. Click My Dashboard > Virtualization > Sprawl.
  2. Locate the Top 10 VMs by Snapshot Disk Usage resource.

    This resource lists the largest snapshots per VM. In this example, syd-hyv-vman-01 holds a number of database backups as snapshots.

  3. To remove snapshots, click Delete Snapshots for syd-hyv-vman-01.

    A page opens with a list of snapshots and their children. The flag icon shows where you are in the list of VMs and snapshots.

  4. Select a snapshot to delete. You can only select one snapshot at a time to delete.

    For this example, you determine Snapshot 3 and all children can be deleted safely. Select the top most Snapshot 3 and the option to delete all children.

  5. Click Delete.

The snapshots are deleted from the VM, reclaiming space. The updated capacity and storage usage totals for the VM display during the next polling.
