Some manuals created or edited before April 15, 2022 did not correctly make backups.
Occurrence Time / Status
On April 15, 2022, this issue was fixed.
As a result of this fix, manuals newly created or edited after April 16, 2022 have backups created correctly.
In addition, we created backups on April 16, 2022 based on the latest information for manuals that were newly created or edited by April 15, 2022, but for which backups had not been created due to this issue.
However, we could not restore the daily automatic backups for each edition that should have been created by April 15, 2022.
We apologize for any inconvenience this may have caused.
We sincerely apologize for the inconvenience.
