This well and truly falls into the “old dog learns new trick” category. <\/p>\n\n\n\n

During a discussion last week about how NetWorker tracks dependencies (a topic near to my heart<\/a><\/strong>), someone mentioned a way to get NetWorker to quickly show dependencies between savesets using nsrim<\/em>. This is something I’d never known about! Instead, in the past, I’d built my own scripts\/utilities to let me display dependency trees for backup chains. It turns out all that effort was unnecessary.<\/p>\n\n\n\n

The trick, it seems, is to get nsrim to run a check for a client in verbose mode, but so that you don’t modify what you’re looking at, you use the -n option to merely display information.<\/p>\n\n\n\n

Here’s what the command and output looks like:<\/p>\n\n\n\n

I love the simplicity of this \u2013 that’s your dependency chain list just printed, one line after the other. The backups are listed in date order allowing you to readily see which backups depend on prior backups.<\/p>\n\n\n\n
Remember, being able to map out dependency chains in NetWorker is a great way to answer that question, why aren’t my backups recycling?<\/em> Other questions, too, but in particular for anyone who grew up with tape, understanding where long dependency chains were building up because of say, a failed full backup has always been an essential activity. <\/p>\n\n\n\n
