Description
There is a bug in Scheduled Action Manager: first backup action terminates the cycle, no more Scheduled Action (SA) are executed.

In normal state, this is not a big issue, as the other SA will be executed in next SA Manager cycle. But it might be an issue if:

• the system reaches the max number of backups and there are lot of backups waiting for execution
• frozen backups, which exhaust backup limit
