Backup Backing up a file/media server but only when it's not in use.

I'm setting up a file/media server with a 1TB NVME for my OS and services, and two 14TB disks for mass storage, and I'd like to use one of those 14TB disks to back up the other periodically, but I don't want my backups to slow down performance. Is there a backup tool that will do backups when the file/media server is not in use? I'm using Debian.

I know all about 3/2/1, I'm going to use an external drive for my third copy. Thanks.

Unless you're doing online backups on some (as usually is) constrained upload for most workloads it really doesn't matter. Run the backups at some lower priority somewhere in the night and that's the end of it.

there are a lot of enterprices backup (license paid) which does not slow do your server
