Hello,

Hello Octovian​ ,

Please refer to Backup failing: [-16915] Backup was aborted

If the article is not sufficient or doesn't help you to identify the cause, please provide more details like how you are initiating the backup; if you are using a local drive or a network drive; see if you can find any potentially related messages in the System, Security or Application event log.

I use a Windows backup schedule, every day starting from 10 p.m. only the data that has been successfully backed up is only 1 to 3 days with only 3 days can't be full 7 days a week, you can ask for enlightenment
