Modifying Rsync script to check source

Hi
I am running rsyncs between a raid attached server and a nas device, which works fine.
I am using the --delete to ensure that its kept in sync. And running a log at the end of the sync for me to check. this i am running from a cron
Problem is if the part of the raid fails on the server the sync still happens resulting the data being wiped on the nas. Is there a way of writing a script that checks that the source data is valid and available before allowing the sync to run.

Code:
rsync -aWv  --stats progress  --delete --ignore-errors --exclude ".DS_Store"  --exclude ".HSancillary"  -- \
exclude ".HSxmap" --exclude ".HSResource"  /Raid/  /mnt/chi-dr/RAID/  \
 >> /mnt/chi-dr/Rsync_Logs/Chi-Raid_rsync.`date +%w`.log 2>&1


Regards
Treds

Mod Comment It's enough to use [CODE] tags for command lines, not for whole posts. And split the command lines if they become too long.

NAME
sync - update super block SYNOPSIS
#include <unistd.h> void sync(void); DESCRIPTION
The sync() function writes all information in memory that should be on disk, including modified super blocks, modified inodes, and delayed block I/O. Unlike fsync(3C), which completes the writing before it returns, sync() schedules but does not necessarily complete the writing before returning. USAGE
The sync() function should be used by applications that examine a file system, such as fsck(1M), and df(1M), and is mandatory before rebooting. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Standard | +-----------------------------+-----------------------------+ SEE ALSO
df(1M), fsck(1M), fsync(3C), attributes(5), standards(5) SunOS 5.11 5 Jul 1990 sync(2)
