    Flashbackup is for Unix

    Flashbackup-Windows is for flashbackup policies on Windows Clients

    MS-Windows is a standard Windows backup

    Flashbackup and Flashbackup-Windows do raw device backups - they tend to be very fast as they back up at block level and backup the entire drive

    So if you have a 50TB drive with 15 TB used you backup will be 50TB!

    You can however restore single file data from these backups - I would advise having a moderate fragment size for you storage unit - say 5000MB - so that when seeking a single file from the backup it can be located easily

    Also test restores from the backup as very large backups can have issues

    Two other differences are that you cannot do the system drive (C drive) using this type of backup and the backup selection list is different .. A windows policy would say D:\ but a Flashbackup-Windows policy will say \\.\D:

    Hope this helps
