Guest Bill Smith Posted October 18, 2008 Posted October 18, 2008 We are using a windows sbs 2003 server. We are backing up to multiple external usb drives that we rotate in and out. YES, the usb drives are formatted with NTFS. There are approx 400GB of free space on each drive. We are using Nova Backup to accomplish the backups. We are backing up approx 40gb. The issue we are having is that when Nova does the backup, it creates several smaller files opposed to just one large backup file. The files are approx 4gb each so I initially thought the external drives were formatted in FAT16 or FAT32 but that isnt the case. I cannot find any setting in Nova Backup that allows you to set it to create just one large file. So I'm thinking it may be a function in the OS somewhere. I want to say that I think in Backup Exec there is an option when backing up to a usb drive to set the backup file size but I couldnt find anything in Nova. Does anyone know how to do this? Is this a SBS option that can be set? If not, does anyone know how to get Nova Backup to do it? Your help would be greatly appreciated! Bill Smith

It's best to post in m.p.windows.server.sbs when you're using SBS - you'll get more expert help that way.

Your help would be greatly > appreciated! > > Bill Smith To work out if this is a Nova or a Windows issue, open a Command Prompt and type the following command: fsutil file createnew U:\big.bin 4000000000 The command will create a 4GByte file on drive U:. If drive U: is an NTFS partition then the file will be created almost instantly. If it is a FAT32 partition then it will fail, or take forever when try a smaller size.
