This review differs from
previous with:
- skip verbose option
(use of log.level).
- use glob.glob to
retrieve files matching rather that os.walk
- fix a bug in
instanceBackupFS that did not return an already existing
backup
- add two functions
to handle instance backup: clearInstanceBackupFS (to remove
one or all backups of an instance), _infoInstanceBackupFS
(just to keep path/pattern info of backup into a single
routine)
