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'
