Title:
  xfsdump doesn't allow levels beyond 0-9

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Hi!

  I've found, quite surprised, that xfsdump doesn't allow dump level
  numbers outside of the range [0-9].  Given that even storing that
  number requires a full byte (8 bits), it boggles the mind why more
  numbers aren't supported.  The usefulness of supporting more numbers
  (24? even 255...) is for taking hourly delta snapshots of live
  filesystems using xfsdump as a backup measure.

  With a simple script one can write a backup that takes a full dump
  (level 0) of the filesystem for the first backup of a given date, and
  all other backups during that day are incrementals (levels are > 0 ...
  i.e. the hour of the day the backup is taken).  However, given that
  the tool only supports [0-9] as the backup level, this seems like an
  arbitrary limitation.

  Is there a real, technical limitation that this level is adhering to?

  Cheers!
