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 allready 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 choosen 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'
