I want to pose a question to other network professionals on Thwack: How long do you retain switch configuration backups stored in NCM?
I have noticed our NCM database starting to get a bit sluggish, especially on the web portal, and I saw that there are some nodes with over 2 years of daily configuration backups stored! I am sure that there are nodes whose backups haven't been purged since they were added to NCM. Diving deeper into the issue, the question of best practices comes up. How many backups are enough to satisfy your own internal disaster recovery requirements? I am hoping that I can get a few varied answers so I have something to stand on when I recommend we get rid of ancient configuration files.
