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

OCF_HEARTBEAT_RSYNCD(7) 					OCF resource agents					   OCF_HEARTBEAT_RSYNCD(7)

NAME
ocf_heartbeat_rsyncd - Manages an rsync daemon SYNOPSIS
rsyncd [start | stop | monitor | meta-data | validate-all] DESCRIPTION
This script manages rsync daemon SUPPORTED PARAMETERS
binpath The rsync binary path. For example, "/usr/bin/rsync" (optional, string, default "rsync") conffile The rsync daemon configuration file name with full path. For example, "/etc/rsyncd.conf" (optional, string, default "/etc/rsyncd.conf") bwlimit This option allows you to specify a maximum transfer rate in kilobytes per second. This option is most effective when using rsync with large files (several megabytes and up). Due to the nature of rsync transfers, blocks of data are sent, then if rsync determines the transfer was too fast, it will wait before sending the next data block. The result is an average transfer rate equaling the specified limit. A value of zero specifies no limit. (optional, string, no default) SUPPORTED ACTIONS
This resource agent supports the following actions (operations): start Starts the resource. Suggested minimum timeout: 20s. stop Stops the resource. Suggested minimum timeout: 20s. monitor Performs a detailed status check. Suggested minimum timeout: 20s. Suggested interval: 60s. validate-all Performs a validation of the resource configuration. Suggested minimum timeout: 20s. meta-data Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5s. EXAMPLE
The following is an example configuration for a rsyncd resource using the crm(8) shell: primitive p_rsyncd ocf:heartbeat:rsyncd op monitor depth="0" timeout="20s" interval="60s" SEE ALSO
