+====== Node backups ======
+Backups are part of the NetYCE lifecycle. As per the [[guides:reference:vendors:vendor_state_actions|state machine]], before and after a configuration change a backup is created.
+Also the NCCM can be used to create backups regularly.
+The protocol used to send the backups for modeled nodes can be changed in the [[menu:design:node_models:hardware|hardware section]].
+This page describe several items for manipulating backup behavior.
+===== Disabling backups =====
+In some cases, like a testlab or until connectivity has been arranged, it is desired to turn off backups for command jobs.
+This behavior is changed per vendor and per command and state.
+Modify the state_actions table under ''Admin > Custom data > State_actions''
+The example below shows that backups have been disabled for:
+  * Vendor_type: Cisco_IOS
+  * Command: cmd_exec
+  * State: preconfig and postconfig
+  * Action: backup
+  * Disabled: set to '1'
+> NOTE: [[menu:admin:users:group_admin|user/group level]] 'system' is required to modify these entries.

+===== Disable tftpd =====
+The following steps will disable the tftp daemon.
+> NOTE: This disables feature like ZTP (Zero touch provisioning) and backups for vendors that only support tftp.
+The use of tftp as a file-transfer protocol can be disabled in NetYCE using the global configuration file
+''/opt/yce/etc/**yce_setup.xml**''
+Locate the line "<daemons>" and change the setting for ''**yce_tftpd**'' to "**disable**". Ensure the ''vsftpd'' daemon is enabled. This controls the ftp server. (use the ''yce'' user to do so.)
+The result is similar to below:
+<code xml>
+<setup>
+  <override>
+    <configs crontab="update" httpd="update" mojo="update" mysql="update" network="update" />
+    <daemons  vsftpd="enable" yce_ibd="disable" yce_nccmd="enable" yce_tftpd="disable" />
+  </override>
+  <yce ...
+</code>
+> Note that disabling tftp server will only prevent tftp transfers, it does not control which transfers protocols will be attempted. The Vendor-specific and Hardware specific (see step 3) settings will define this behavior.
+As ''yce'' unix user run ''yce_setup.pl -r'' to regenerate config files for above config to be effective and restart daemons. At this point the tftp server will no longer be available.
+For each vendor_type and model you may choose to use a different transfer protocol, if it was set to tftp or the default behavior was using tftp. You may see the defaults in the [[guides:reference:vendors:supported_devices|supported hardware]] table.
