NAME¶

storeBackupCheckBackup.pl - checks if a file in the backup is missing or corrupted

SYNOPSIS¶

        storeBackupCheckBackup.pl -c backupDir [-p number] [-i]
              [-w filePrefix] [--lastOfEachSeries] 
              [--includeRenamedBackups] [-T tmpdir]
              [--logFile
               [--plusLogStdout] [--suppressTime] [-m maxFilelen]
               [[-n noOfOldFiles] | [--saveLogs]]

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.

IT calculates md5 sums from the files in the backup and compares them with md5 sums stored by storeBackup.pl. It so will recognize, if a file in the backup is missing or currupted. It only checks plain files, not special files or symbolic links.

OPTIONS¶

--print

    print configuration parameters and stop
    

--checkDir, -c

    backup or top of backups to check
    

--backupRoot, -b

    generated:
    /tmp/bugsB-files.missing.txt
    /tmp/bugsB-md5sums.missing.txt
    /tmp/bugsB-md5sums.wrong.txt
    if you change option tmpdir to something else, this value will be

--logFile, -l
