+Check if iso files of rear backup are not out of date.
+You can customize the values for
+* backup directory
+* limits for warning and critical
+
+This plugin sends performancedata.

+SYNTAX:
+
+ $_self [-h] [--dir PATH] [--critical VALUE] [--warning VALUE]
+
+OPTIONS:
+
+ -h, --help
+ this help
+
+PARAMETERS:
+
+ -d, --dir PATH
+ set installation dir of iml deployment to find its check skript
+ default dir: ${dir_reardata}
+
+ -c, --critical VALUE
+ critical level in days (default: $iLimitCritical)
+
+ -w. --warning VALUE
+ warning level in days (default: $iLimitWarning)
+
+EXAMPLE:
+
+ $_self
+ Check backup data with initial values
+
+ $_self -d /data/mybackups
+ Check iso files a given directory
+
+ $_self -d /data/mybackups -w 14 -c 28
+ Check iso files a given directory and customized limits
