Norton 360 ver. 25.5.10141 (build 25.5.10141.934) no longer supports previous local backup sets

Hello @GEORGEL_WESTLUND
and by an older version compatible with those old backup sets. Does Norton mean N360 v22.x?
and do you have access to the N360_Backup folder?

Note: my Norton 360 v25.5 recognizes my local backups from Feb 2025.
Your old backup sets were created with N360 v22.x?

Sorry…no idea if ARestore will help.
