The important part about configuring this command is that the user selects a time that does not interfere with any other network activity to the shared folders that may be scheduled. For example, if one is using the Raspberry Pi NAS as a backup destination for some sort of automated software that copies the files to the NAS at 5AM every morning, then the user needs to either adjust the backup time in the backup software or the user needs to adjust the time for the cron job on the Pi—but one can not have both the remote backup dumping data onto the network share and the Raspberry Pi trying to sync that data between local drives at the same time. Once the user has entered the crontab entry, click CTRL+X to exit and save the file. If the user wishes to run the rsync immediately to get the data mirrored faster and make the initial cron job a little lighter on the system, go ahead and enter the same rsync command that one put into the crontab at the command line like the code shown here and then press enter.
