It might help if you could clarify which files exactly you are searching for. If, for instance, a file exists in dir1 and dir2, but not in dir3 and dir4, should it be included or not? How about a file existing in dir1, dir2, dir3 but not in dir4? Does "dir1" take any precendence or should a file existing in dir1 and dir2 but not in dir3 and dir4 be treated the same as one existing in dir2 and dir4 but not in dir1 and dir3?

In other words, could you clarify the rules by which you want to find files? A possible solution (maybe not even relying on "diff") wil depend on how you answer these questions.

I hope this helps.

raidfile-config

RAIDFILE-CONFIG(8)						    Box Backup							RAIDFILE-CONFIG(8)

NAME

       raidfile-config - Configure Box Backup's RAID files

SYNOPSIS

       raidfile-config config-dir blocksize dir1 [dir2 [dir3]]

DESCRIPTION

       raidfile-config creates a raidfile.conf file for Box Backup. This file holds information about the directories used to store backups in.
       Box Backup supports userland RAID, in a restricted RAID5 configuration, where 3 and only 3 'drives' are supported. You can read more about
       RAID5 (and other RAID-levels) here[1].

   Parameters
       The parameters are as follows:

       config-dir
	   The directory path where configuration files are located. Usually this is /etc/box.	raidfile.conf will be written in this directory.

       blocksize
	   The block size used for file storage in the system, in bytes. Using a multiple of the file system block size is a good strategy.
	   Depending on the size of the files you will be backing up, this multiple varies. Of course it also depends on the native block size of
	   your file system.

       dir1
	   The first directory in the built-in RAID array.

       dir2
	   The second directory in the built-in RAID array. If you are not using the built-in RAID functionality, this field should be ignored.
	   You should not use the built-in RAID if you have a hardware RAID solution or if you're using another type of software RAID (like md on
	   Linux).

       dir3
	   The third directory in the built-in RAID array. The same notes that apply to dir2 also apply to dir3.

       Note that there are currently no way to add multiple disk sets to the raidfile.conf file using command line tools, etc. See
       raidfile.conf(5) for details on adding more disks.

BUGS

       there.

       To report a bug, give us at least the following information:

       o   The version of Box Backup you are running

       o   The platform you are running on (hardware and OS), for both client and server.

       o   If possible attach your config files (bbstored.conf, bbackupd.conf) to the bug report.

       o   Also attach any log file output that helps shed light on the problem you are seeing.

       o   And last but certainly not least, a description of what you are seeing, in as much detail as possible.
