Jenkins CI: exposed spaces and their respective life times — do not confuse with: artifacts, archives, …

• https://wiki.jenkins-ci.org/display/JENKINS/Copy+To+Slave+Plugin – transferring files back and forth between master and slave(s)

There are various exposed spaces provided by a Jenkins master:

• https://JENKINS_MASTER/jenkins/userContent/ — general shared, long-term space — no automatic purging
• https://JENKINS_MASTER/jenkins/job/YOUR_JOB/ws/ — that’s quite obviously “per job” long-term “workspace” — no automatic purging
• … “per job”, “per build” middle-term space … — will get removed automatically, once the particular build run gets outdated and purged — but you may determine to “keep this build forever“
