rsync - transactional sync with multiple nodes

Hi Everyone,

We have a requirement to sync files with multiple nodes. We need to run the rsync sequentially on each node, if one of the node fails we need to recover the files to previous state in all nodes. I know that we have backup option in rsync which takes the backup of files before applying changes to destination folder.

I have few questions on this
1. How can we achieve the above transactional sync requirement using backup option? Any thoughts...
2.I think rsync performs file by file transfer.. is there any option to take total
backup(--backup) in backup folder first and after complete backup apply changes(sync) with destination?

Thanks !

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
