Data Purge Policy
The LNF provides a file server (ssel-files.eecs.umich.edu) to users so that data from tools can be saved in the lab, and later retrieved in the CAD room. This service is intended for short-term use. Users should remove files from the shared folder as soon as possible and transfer to their own storage (usb drive, box.net, etc).
No USB memory sticks are allowed on instruments or tools computers, unless explicitely approved by the tool engineers.
There are now two shared folders on the file server (ssel-files.eecs.umich.edu).
Files contains all user generated data from tools that was created or modified in the past 90 days. This location contains a subfolder for each tool. Uses can create a folder in each tool subfolder for their data. There is also a users subfolder where design files can be saved. All user data older than 4 months will be purged on the same schedule as the chemical purge.
Archive contains all user generated data from tools that is more than 90 days old. This is a temporary folder that will go away once old files are either purged or moved to Files. No new files can be saved to this location.
Starting May 1, 2019 We will purge (i.e. delete) any file from Archive that has not been modified in the last 4 months, then there will be a regular file purge every 4 months using the same schedule as the chemical purge. Once Archive is empty and removed Files will be purged on the same schedule.
