Two possibilities I have come across when ERASEFILES doesn't work as expected:
- the backup files password has changed, causing SQL Backup not to be able to read the header in the backup file
- de-duplication is used, causing the file attributes to change and not meet SQL Backup's expected file attributes
- the backup files password has changed, causing SQL Backup not to be able to read the header in the backup file
