SQL 2012 :: Copy Backup Files From One Server To Another?

I've an emergency requirement to copy Source server database backup files to destination Server through xcopy command. Backup job on source server runs daily, so once this job get completes all databases backups needs to be moved to destination server. But here the main concern is "the backup files on destination server shouldn't be overwritten, they should be placed separately as Source server job runs daily".

We've a command which overwrites backups on destination server. But we need to keep backups on destination at-least for 4 weeks (means : retention should be 4 Weeks).
