Thanks Azhrei
We're using a JBOD at the moment so it's a raid configuration of sorts.

My colleague is using a program called robocopy (similar to rsync) to get this ever changing data over to another disk (as a kind of resilience option). I've pointed out to them that there's a purge function in robocopy which will copy all the files that have changed, and also delete files that need deleting.

However, they are convinced that this particular feature is somehow cursed and we'd be at risk of losing all the data!

Therefore, I need to prove to them that, over time, their method could well be degrading the disks.

Convining them to use the 'few files at a time' is extremely difficult and they're set in their ways at the moment!

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
