Project cleanup

Project cleanup is useful when a Project is rapidly growing and changing. A lot of changes will decrease performance over time. Also the snapshot history can take up a huge chunk of disk space on both AI Hub and your local disk.

This documentation is for you if:

  1. you connect to Altair AI Hub and
  2. your Projects there are periodically cleaned up.

A Project cleanup on Altair AI Hub implies a drastic change to the Project's status, because it effectively wipes out the Project's Snapshot History. When, after a cleanup, you Get updates, you will only see the latest Snapshot. Whether the older Snapshots are still available depends on the setting Keep cleaned-up Project in the archive. If an archive exists, you can view it on Altair AI Hub.

Hence, when you choose Get updates to update your copy of the Project from the Project Server, you must consider the following scenarios:

Scenario No local changes Local changes exist
No archive All Snapshot History is lost (Optional) Local changes archived in Altair AI Studio
Archive exists Snapshot History lives in the archive on Altair AI Hub (Optional) Local changes archived in Altair AI Studio

When you select Get updates in Altair AI Studio, these scenarios unfold as follows:

  1. There are no local changes, and archiving is deactivated.

    • Cancel to do nothing
    • Overwrite your copy of the Project. All Snapshot History is lost.

    • Cancel to do nothing
    • Archive local changes will archive the current state of your Project and create a new folder on your filesystem. Then it will overwrite your copy of the Project.
    • Overwrite your copy of the Project. All Snapshot History is lost.

    • Cancel to do nothing
    • Archive local changes will archive the current state of your Project and create a new folder on your filesystem. Then it will overwrite your copy of the Project.
    • Overwrite your copy of the Project. The Snapshot History now lives in the archive on the Project Server.
