NAME

       storeBackupCheckSource.pl - compares unchaged files in source with their
                                   md5 sums in the backup

DESCRIPTION

       The tool is intended to find files in the source that might have changed over time without the users
       interaction or knowledge, for example by bit rot.

       If a file is unchanged (same ctime, mtime, size) in the source directory compared to the backup, it:

       - prints an ERROR message if the md5 sum differs

       - prints a WARNING if permissions, uid or gid differs

       - prints MISSING if file is not in the source directory (option -v)

       - prints INFO if file is identical (option -v)

SYNOPSIS

           storeBackupCheckSource.pl -s sourceDir -b singleBackupDir [-v]
                     [-w filePrefix]
                     [--logFile
                      [--plusLogStdout] [--suppressTime] [-m maxFilelen]
                      [[-n noOfOldFiles] | [--saveLogs]]

OPTIONS

       --sourceDir, -s
                   source directory of backup when running storeBackup.pl

       --singleBackupDir, -b
                   directory of the backup to compaire sourceDir with
                   this must be *one* single backup directory
                   (eg. 2012.08.08_02.00.11)

       --verbose, -v
                   also print positive messages (file is identical in source and backup)

       --wrongFileTables, -w
                   write filenames with detected faults in regular files for
                   later bug fixing (not automated)
                   parameter to this option is a file prefix
                   eg. if the file prefix is '/tmp/bugsS-', the following files are
                   generated:
                   /tmp/bugsS-files.missing.txt
                   /tmp/bugsS-md5sums.wrong.txt

       --logFile, -l
                   logFile, Default: stdout

       --plusLogStdout
                   if you specify a log file with --logFile you can
                   additionally print the output to STDOUT with this flag

       --suppressTime
                   suppress output of time in logfile

       --maxFilelen, -m
                   maximal length of log file, default = 1e6

       --noOfOldFiles, -n
                   number of old log files, default = 5

       --saveLogs
                   save log files with date and time instead of deleting the
                   old (with [-noOfOldFiles])

       --compressWith
                   compress saved log files (e.g. with 'gzip -9').
                   default is 'bzip2'
