Basic Rules

Every day around 3:20 AM, items that differ from the previous day (information that has been updated or newly created) are automatically backed up.

Changes Considered as "Differences"

When any of the following information is changed in the editing data on the server, it becomes subject to automatic backup.

  • Cover information (title, image, description)
  • STEP information (title, image, description)
  • Search tags
  • Adding/deleting comments

※ Changes such as folder changes or Good Jobs are not considered "differences".
※ Archived manuals are not subject to automatic backup.

Backup Priority

If edits are made multiple times in one day, the version edited closest to 3:20 AM will be automatically saved. ※ However, if a manual backup is performed before 3:20 AM, that data will be retained.

Backup Retention Period (30 Days)

You can go back up to 30 days.

Example: When restoring at 4:00 PM on 5/15, you can select and duplicate from backups dated on or after 30 days prior (as of 3:20 AM on 4/16).

If No Edits Were Ever Made

For example, if a manual created on 3/16 that was never edited is accidentally deleted as of 5/15, you can restore it by going back to the state on 4/16 (the backup including the point at 3:20 AM on 4/16, which is 30 days prior).

How Restoration Works: "Duplication" Rather Than Overwriting

Restoring a backup does not overwrite the existing manual. A new manual containing the past data is "newly created."

  • Regarding the URL: A new URL will be issued, so if you wish to keep the original URL, please use the clipboard feature to transfer the contents.
  • Regarding the owner: The user who performs the restoration (duplication) will become the owner of the new manual.

Data That Is and Is Not Carried Over

Items That Are Carried Over

  • Cover and STEP information (title, images/videos, edited content, description, related URLs, etc.)
  • Folder and subfolder information
  • Search tags, comments, Good Jobs
  • View count, manual rating
  • Creation date and time

Items That Are Not Carried Over (Reset or Changed)

  • Revision history: Will be blank
  • Last updated time: Will be set to the time the restoration was performed
  • Publication status: Will be created in "Draft" status
  • Approval request status: Will be set to not submitted (-)
  • Public URL: A new URL will be issued
  • Bookmarks: Will be removed

[Supplementary Note] Re-editing Video Edit Information

Re-editing of videos is only available for backups created on or after 2:00 PM on July 31, 2020.
Data from before that time will be restored with the video edits fixed in place, and the edit content cannot be re-edited.
