[feature request]is there any plan to support limiting the copy speed?

when taking full backup, xtrabackup needs to copy all data files,
and at that time, the i/o util on mysql server will getting close to 100%, network bindwidth too,
which may impact mysql usage, and we get lots of alert.
so i wonder if there is a plan to add a new parameter like --chunk-time which is similar to pt-osc,
so we can limit the copy speed.
thanks in advance.

is there someone have an eye on it?


i missed it!!! thanks for your reply.
