Is Rsync safe to use on a drive that is in use?

Is Rsync safe to use on a drive that is in use?

I am setting up a nightly cron job to run rsync (with --delete) to synchronize network shares with their respective backup volumes.
Will I run into any trouble if there is a lot of activity on the source drive during the time that the rsync process is running?
For example, there may be a long running copy command transferring GBs of data that overlaps the rsync cron job. Could there be concurrency issues?
