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

    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
