= About volume snapshots

[role="_abstract"]
You can create volume snapshots of persistent volume claims (PVCs) provisioned by {lvms} to back up application data or revert to a previous state, providing data protection and recovery capabilities.

You can perform the following actions using the volume snapshots:

* Back up your application data.
+
[IMPORTANT]
====
Volume snapshots are located on the same devices as the original data. To use the volume snapshots as backups, you must move the snapshots to a secure location. You can use OpenShift API for Data Protection (OADP) backup and restore solutions. For information about OADP, see "OADP features".
====

* Revert to a state at which the volume snapshot was taken.

[NOTE]
====
You can also create volume snapshots of the volume clones.

== Limitations for creating volume snapshots in multi-node topology
{lvms} has the following limitations for creating volume snapshots in multi-node topology:

* Creating volume snapshots is based on the LVM thin pool capabilities.
* After creating a volume snapshot, the node must have additional storage space for further updating the original data source.
* You can create volume snapshots only on the node where you have deployed the original data source.
* Pods relying on the PVC that uses the snapshot data can be scheduled only on the node where you have deployed the original data source.
