backing up other backups

[southcityguy 0]

I run a nearly all Mac shop with a Windows 2003 server in the mix. I currently use Retrospect 6 workgroup on a mac to back up nearly the entire network. I also run Retrospect 7 on the MS server and that backs up to a folder on it's own HD and to tape. However, I want everything in one place as I nightly swap FW drives on the Mac backup server to take home with me. Soooo, my question, I have been backing up the folder on the MS server with the Mac version of Retrospect (using SFM) so that I can get that data onto the nightly off site drives. Is this a valid procedure? In other words, should we have a disaster, will I be able to recover that Windows Retrospect (and I should add SQL data from Great Plains data) from the Mac backup?

 

Thanks,

Ben
