Backup file got removed from the remote machine.

When a backup is deleted from the Junos Space UI, it is also removed from the server. This is expected and the default behaviour.

If the customer is using a purging policy under:

Junos Space Administration → Purging Policy

Then the system will automatically retain or delete backups based on the configured policy settings. The UI reflects this policy by showing only backups that are still valid according to the purge criteria; any backups exceeding the policy threshold are removed from both the UI and the server.
