WARNING

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

OPTIONS

--file, -f

    configuration file (instead of parameters)

--print

    print configuration read from configuration file and stop

--backupDir, -b

    top level directory of all backups (must exist)

--series, -S

    directory of backup series
    same parameter as in storeBackup / relative path
    from backupDir, default is 'default'

--lockFile, -L

    lock file, if exists, new instances will finish if
    an old is already running, default is $lockFile

--doNotDelete

    test only, do not delete any backup

--deleteNotFinishedDirs

    delete old backups which where not finished
    this will not happen if doNotDelete is set

--keepAll

    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;

--keepWeekday

                    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)

--keepFirstOfYear

    do not delete the first backup of a year
    format is timePeriod with possible 'archive flag'

--keepLastOfYear

    do not delete the last backup of a year
    format is timePeriod with possible 'archive flag'

--keepFirstOfMonth

    do not delete the first backup of a month
    format is timePeriod with possible 'archive flag'

--keepLastOfMonth

    do not delete the last backup of a month
    format is timePeriod with possible 'archive flag'

--firstDayOfWeek

    default: 'Sun'. This value is used for calculating
    --keepFirstOfWeek and --keepLastOfWeek

--keepFirstOfWeek

    do not delete the first backup of a week
    format is timePeriod with possible 'archive flag'

--keepLastOfWeek

    do not delete the last backup of a week
    format is timePeriod with possible 'archive flag'

--keepDuplicate

    keep multiple backups of one day up to timePeriod
    format is timePeriod, 'archive flag' is not possible
    default = $keepDuplicate;

--keepMinNumber

    Keep that miminum of backups. Multiple backups of one
    day are counted as one backup. Default is 10.

--keepMaxNumber

    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

--keepRelative, -R

    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.

--logFile, -l

    log file (default is 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 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 [-noOldFiles])

--compressWith

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