Data Avoidance

Data Avoidance technologies typically contribute the most to data efficiency because they prevent the creation of unnecessary data, which also minimizes the need for more resource-demanding data reduction technologies.

Deleting old VMs older than 2 years

Hello everyone,I currently have several old VMs that have been turned off for more than 2 years. No one in my workplace can tell me or remember what are they for. I am considering deleting them (to release storage), but before doing that is there something I should check before? Could those VMs be connected with online VMs in anyway for production?Could I take a useful snapshot, even though I will delete the VM afterwards?
