3CX Linux multiple backup

[linking13]

I have scheduled a backup via FTP at 1:00 AM but if I'll see the content of the detination folder I notice that there more then a backup around that time. Same situation in the log via GUI (I suppose that read the content of the folder)

How can I check why there is a multiple schedule?

I don.t know how and why but now has began to respect the schdule. Pherhaps the NTP client installed?
