When I used version 2 the following script was in the help file and worked just fine for my needs.
Delete "E:\Backup-5.zip"
Rename "E:\Backup-4.zip" "E:\Backup-5.zip"
Rename "E:\Backup-3.zip" "E:\Backup-4.zip"
Rename "E:\Backup-2.zip" "E:\Backup-3.zip"
Rename "E:\Backup-1.zip" "E:\Backup-2.zip"
Backup "RotationBackupJob"
Now that I'm using version 3, the script fails after the first line with the following error.
Cannot run lua file: [string "Delete "E:\Backup-5.zip"..."]:2: '' expected near '\'
I've looked through the help file and tried some other things but cannot get it to work. Any help would be much appreciated.
