A Storage Manager (SM) that is executing a hotcopy does so in addition to its usual operations. That is, a hotcopy operation does not block other SM operations.
You should not notice any performance degradation during a hot copy operation.

The time it takes to perform a hotcopy depends on how much information is being copied.
It can take a while for a very large database (full backup) or if there are large number of changes (incremental or journal backup).
The default behavior is that

hotcopy so that it does not return immediately, specify a value for the

More information is available using hot copy logging. This section also covers hot copy error messages.
