Yes, I've read this.
"When both options are checked, Modification time has higher priority. As a consequence, file is not considered updated, despite having different size, if it is older."
Unfortunatelly this does not allow to solve auto-backup problem if remote timestamp is newer than local one and remote file is corrupted (different size). This file is simply skipped...
So my question is still open:
Is there existing option or any chance to add such feature to have WinSCP option "Force overwrite if different (timestamp OR size)" for local->remote and remote->local syncs?
Hint 1: with this option enabled, during auto-backup, local file should be copied if there is a difference in size and local file is OLDER than remote one. Now WinSCP skips such file because it is older.
Hint 2: After sync, remote dir must be exacly the same as local dir (true mirror-backup requirement).
Using delete + copy from the beginning is not an option (to much data).
Turning off timestamp comparsion and leaving only size comparsion is not an option in backup scenario.
