If we have any listing problem, we should stop comparing difference
between source & target lists because it is already so hard to know
what mc should do next. So, let's inform users and let them deal
with the problem.
Added exclude options to exclude unwanted system files.
Exclude option excludes the source files/objects that match
the passed shell file name pattern
Fixes#1903
Currently `mc mirror` requires source to be
uploaded only if the size is different than the
object on remote server. This PR adds support to
check for last modified time of the source object
as well such that we upload if there are timestamp
differences as well.
Fixes#2187
This fixes#1889.
```sh
mc mirror -w
```
Now runs continous even when the source is not available.
Reconnects indefinitely in a binomially increasing fashion
and also allows jitter so that the retry has a nice
distribution as well.
This allows for 'mc mirror -w' to run continously without
further monitoring.
