Hi,
Please advise me if what i'm doing is makes sense and is an accepted mechanism for taking backups or if there is any other procedure that i can emplpoy to avoid unnecessarily archiving gigabytes of WAL logs which may be growing many times the size of the actual data directory.
Thanks and Regards,

The problem is that rsync isn't copying all the xlog files created during the time the rsync is taking place, which is why it is complaining that there are files missing.
There may be other logical flaws with your process as well.
Something similar to the steps given in "Starting Replication with only a Quick Master Restart" as laid out in the wiki tutorial on binary replication might give you a way to make this work. (You probably won't need the restart of the master, since you're not actually setting up replication, so you won't be changing the postgresql.conf file on your master.)
This uses a two-step process. First you copy all the files EXCEPT the ones on pg_xlog, then you copy those files, so you have a complete set.
