     	- Instead of forcing a sync based on the number of deleted files, you may consider the `ADD_DEL_THRESHOLD` feature, by allowing a sync that would otherwise violate the delete threshold, if the ratio of added to deleted files is greater than the value set. 
     - If parity info is out of sync **but** the number of deleted or changed files did not exceed the threshold, it **executes a sync** to update the parity info.
 - When the parity info is in sync, either because nothing has changed or after a successfully sync, it runs the `snapraid scrub` command to validate the integrity of the data, both the files and the parity info. If sync was cancelled or other issues were found, scrub will not be run. 
-    - Note that each run of the scrub command will validate only a configurable portion of parity info to avoid having a long running job and affecting the performance of the server.

     - Scrub frequency can also be customized in case you don't want to do it every time the script runs. 
     - It is still recommended to run scrub frequently. 
 - Extra information can be added, like SnapRAID's disk health report or SnapRAID array status.  
 - When the script is done sends an email with the results, both in case of error or success, and triggers any 3rd party notifications configured.
