Permissions error when restoring backup

Issue

• We are trying to restore a PRO environment backup into DEV environment. And we see in the log several errors related to Document Library when decompressing:

• We did read Fast Track article Backup doesn't have permissions to open the Document Library but we restored some backups with Backup Service version > 5.16.0 and we did not have any problem with it. At present, we have deployed Backup Service version 5.22.1

Environment

• Liferay DXP PaaS.
• Backup Service version 5.22.1

Resolution

• This situation could happen when a services deployment is running and, at the same time, a backup restore is also executing.
• Backup Service version >= 5.22.1 includes https://liferay.atlassian.net/browse/LCD-32784 and https://liferay.atlassian.net/browse/LCD-33293 . Both fixes change permissions to avoid root user in Document Library when the Backup Service is deployed. 
• This bulk permissions change conflicts with the current backup restore operation.
• Thus, to avoid this conflict do not make converge both processes: services deployment and backup restore.

Additional Information

• 02/04/2025 - Service Release Updates
