Rsync better use for backup

Hello,

I have a list of working directory in a remote computer acesssible through ssh and the same directory structure in my home directory of my laptop. I sometimes work on both my laptop and my this other computer.

I usually use Rsync this way to synchronize files

Code:
rsync remotehost@remoteDirectory -auzv /local Directory 
rsync -auzv  /local Directory  remotehost@remoteDirectory

I run both of these as a shell script

This seems to work fine, but the problem that I face is that if I edit a file's nae in the local Host. or delete a file in the remote Host then when I execute these two commands, I get the old files + the new files in both places.

Thus before doing rsync, I would like to (say use ls and diff) to find out which files are not present in the Local Directory but present in the Remote Directory and which files vice versa.

Then I can check for those files, delete them or not, and then do these rsync commands.

If its possible to automate these things, with some better shell scripting than just simple rsync ?

also I want to know how useful is Crontab for these kinds of work. , or can I make Crontab run when both machines are on at a particular point of time in the day / week ?

rsync_selinux(8)					rsync Selinux Policy documentation					  rsync_selinux(8)

NAME
rsync_selinux - Security Enhanced Linux Policy for the rsync daemon DESCRIPTION
Security-Enhanced Linux secures the rsync server via flexible mandatory access control. FILE_CONTEXTS SELinux requires files to have an extended attribute to define the file type. Policy governs the access daemons have to these files. If you want to share files using the rsync daemon, you must label the files and directories public_content_t. So if you created a special directory /var/rsync, you would need to label the directory with the chcon tool. chcon -t public_content_t /var/rsync To make this change permanent (survive a relabel), use the semanage command to add the change to file context configuration: semanage fcontext -a -t public_content_t "/var/rsync(/.*)?" This command adds the following entry to /etc/selinux/POLICYTYPE/contexts/files/file_contexts.local: /var/rsync(/.*)? system_u:object_r:publix_content_t:s0 Run the restorecon command to apply the changes: restorecon -R -v /var/rsync/ SHARING FILES
If you want to share files with multiple domains (Apache, FTP, rsync, Samba), you can set a file context of public_content_t and pub- lic_content_rw_t. These context allow any of the above domains to read the content. If you want a particular domain to write to the pub- lic_content_rw_t domain, you must set the appropriate boolean. allow_DOMAIN_anon_write. So for rsync you would execute: setsebool -P allow_rsync_anon_write=1 BOOLEANS
system-config-selinux is a GUI tool available to customize SELinux policy settings. AUTHOR
