Some of my customers do not see the Client Side Backup tab in their Customer Panels.
Creation of client-side backups is prohibited for the Virtuozzo node the Containers in question are located on.
To make the Client Side Backup tab appear in Customer Panels, please go
Top > Service Director > Virtuozzo Manager > Setup > Nodes Backup Settings > Virtuozzo node of the Container(s) in question and enable the "Allow creation of client-side backups" option there.
NOTE: The option "Allow creation of client-side backups" cannot be enabled for PVC 4.6/4.7 nodes. This option is not available by design, there is a feature request to make it available again, the FR number is PBAS-26923.
