  !!! USAGE IN PARALLEL WITH storeBackup.pl CAN DESTROY YOUR BACKUPS !!!

    configuration file (instead of parameters)
    
    print configuration read from configuration file and stop
    
    top level directory of all backups (must exist)
    
    directory of backup series
    same parameter as in storeBackup / relative path
    from backupDir, default is 'default'
    
    lock file, if exists, new instances will finish if
    an old is already running, default is $lockFile
    
    test only, do not delete any backup
    
    delete old backups which where not finished
    this will not happen if doNotDelete is set
    
    keep backups which are not older than the specified amount
    of time. This is like a default value for all days in
    --keepWeekday. Begins deleting at the end of the script
    the time range has to be specified in format 'dhms', e.g.
    10d4h means 10 days and 4 hours
    default = $keepAll;
    
                    keep backups for the specified days for the specified
                    amount of time. Overwrites the default values chosen in
                    --keepAll. 'Mon,Wed:40d Sat:60d10m' means:
                        keep backups of Mon and Wed 40days + 5mins
                        keep backups of Sat 60days + 10mins
                        keep backups of the rest of the days like spcified in
                                --keepAll (default $keepAll)
                    if you also use the 'archive flag' it means to not
                    delete the affected directories via --keepMaxNumber:
                       a10d4h means 10 days and 4 hours and 'archive flag'
                    e.g. 'Mon,Wed:a40d Sat:60d10m' means:
                        keep backups of Mon and Wed 40days + 5mins + 'archive'
                        keep backups of Sat 60days + 10mins
                        keep backups of the rest of the days like specified in
                                --keepAll (default $keepAll)
    
    do not delete the first backup of a year
    format is timePeriod with possible 'archive flag'
    
    do not delete the last backup of a year
    format is timePeriod with possible 'archive flag'
    
    do not delete the first backup of a month
    format is timePeriod with possible 'archive flag'
    
    do not delete the last backup of a month
    format is timePeriod with possible 'archive flag'
    
    default: 'Sun'. This value is used for calculating
    --keepFirstOfWeek and --keepLastOfWeek
    
    do not delete the first backup of a week
    format is timePeriod with possible 'archive flag'
    
    do not delete the last backup of a week
    format is timePeriod with possible 'archive flag'
    
    keep multiple backups of one day up to timePeriod
    format is timePeriod, 'archive flag' is not possible
    default = $keepDuplicate;
    
    Keep that miminum of backups. Multiple backups of one
    day are counted as one backup. Default is 10.
    
    Try to keep only that maximum of backups. If you have
    more backups, the following sequence of deleting will
    happen:
            - delete all duplicates of a day, beginning with the
              old once, except the oldest of every day
            - if this is not enough, delete the rest of the backups
              beginning with the oldest, but *never* a backup with
              the 'archive flag' or the last backup
    
    Alternative deletion scheme. If you use this option, all other
    keep options are ignored. Preserves backups depending
    on their *relative* age. Example:
    -R '1d 7d 2m 3m'
        will (try to) ensure that there is always
        - One backup between 1 day and 7 days old
        - One backup between 5 days and 2 months old
        - One backup between 2 months and 3 months old
        If there is no backup for a specified timespan
        (e.g. because the last backup was done more than 2 weeks
        ago) the next older backup will be used for this timespan.
    
    log file (default is STDOUT)
    
    if you specify a log file with --logFile you can
    additionally print the output to STDOUT with this flag
    
    suppress output of time in logfile
    
    maximal length of file, default = 1e6
    
    number of old log files, default = 5
    
    save log files with date and time instead of deleting the
    old (with [-noOldFiles])
    
    compress saved log files (e.g. with 'gzip -9')
    default is 'bzip2'
