interval in a launchd script
Hi,
i'm planning a to automate my backup with a rsync user deamon in my launchd and let that run every 2 hours.
my server contains a lot of video data which can expand rapidly , up to 1TB, in an interval of 2 hours.
now i'm wondering what will happen when a rsync is running longer then the interval and the next command is already given. will it abort one of them? place them in a cue? or will it start running anyway? in the last case i can imagine that this will cause incomplete/corrupt files on my backup filesystem.
does anyone know the answer to this?
thanks in advance,
wessel

Help plz
Does any one have any idea how to compare interval ranges of 2 files.
finding 1-4 (1,2,3,4) of input2 in input1 of same key "a" values (5-10, 30-40, 45-60, 80-90, 100-120 ). Obviously 1-4 is not one of the range with in input1 a. so it should give out of range.

CORE(5) BSD File Formats Manual CORE(5)
NAME
core -- memory image file format
SYNOPSIS
#include <sys/param.h>
DESCRIPTION
A small number of signals which cause abnormal termination of a process also cause a record of the process's in-core state to be written to
disk for later examination by one of the available debuggers. (See sigaction(2).) This memory image is written to a file named by default
core.pid, where pid is the process ID of the process, in the /cores directory, provided the terminated process had write permission in the
directory, and the directory existed.
The maximum size of a core file is limited by setrlimit(2). Files which would be larger than the limit are not created.
The core file consists of the Mach-O(5) header as described in the <mach-o/loader.h> file. The remainder of the core file consists of vari-
ous sections described in the Mach-O(5) header.
NOTE
Core dumps are disabled by default under Darwin/Mac OS X. To re-enable core dumps, a privileged user must do one of the following
* Edit /etc/launchd.conf or $HOME/.launchd.conf and add a line specifying the limit limit core unlimited
* A privileged user can also enable cores with launchctl limit core unlimited
* A privileged user can also enable core files by using ulimit(1) or limit(1) depending upon the shell.
SEE ALSO
gdb(1), setrlimit(2), sigaction(2), Mach-O(5), launchd.conf(5), launchd.plist(5), sysctl(8)
HISTORY
A core file format appeared in Version 6 AT&T UNIX.
