+=== Checkpointing
+
+When a full backup is requested, it always triggers a checkpoint.
+The backup cannot proceed until the checkpoint finishes.
+
+While the server is checkpointing, the backup job receives no data, which may lead to the backup timeout.
+To extend the backup timeout, modify the xref:configuration/configuration-settings.adoc##config_causal_clustering.catch_up_client_inactivity_timeout[`causal_clustering.catch_up_client_inactivity_timeout`] setting, which restricts the network inactivity.
+It controls the timeout duration of the catchup protocol, which is the underlying protocol of multiple catchup processes, including backups.
+
+You can also tune up xref:configuration/configuration-settings.adoc#_checkpoint_settings[the Checkpoint settings] or check that your disks are performant enough to handle the load. 
+For more information, see xref:performance/disks-ram-and-other-tips.adoc#performance-checkpoint-iops-limit[Checkpoint IOPS limit].
