Hi,
The Microsoft Q&A forums are currently in English only.
Translation from Google Translate:
I have a server with windows server 2019 STD installed everything running normal, the people are working normally too, the question is, I would like to make a single bare-metal backup, I can do this type of backup with the people working, or to do this type of backup, does everyone have to stop working so I can do the backup?
There may be differences on the backup software, but nowadays there shouldn't be any issues when performing a bare-metal recovery (BMR) backup during work hours, you might consult with your backup vendor but I'm fairly sure this shouldn't be a problem.
Best regards,
Leon
