You should now be able to create automated backups of your Cacti installation as well as do some basic maintenance work.
You have created an automated database and file backup and learned which files are needed to create a complete Cacti backup along with all important files. Using this backup, you have performed a restore of the database as well as single files. As the Cacti logs grow constantly, you have configured the integrated log file rotation feature of Cacti to create daily log files. You've also looked at the process of checking for orphaned RRD files and how to delete these. Finally, by using the Cacti repair utilities, you have seen how to utilize these CLI scripts for repairing templates and the database.
You should now be able to perform some basic Cacti maintenance tasks. In the next chapter, you're going to learn how to retrieve performance data from network devices and servers using various methods.
