Re: backup of Dual boot Ubuntu and Windows 7
Haven't used Ghost or Acronis in years -- so I can't advise you on those. I use Macrium Reflect (MR) for Window backups and Clonezilla for Linux backups -- but I don't think MR handles Linux filesystems.
I have generally found that Windows utilities do a better job of backing up and restoring Windows, and Linux utilities do a better job of backing up and restoring Linux.
So, by choice, I do NOT use a single backup/restore solution for both Windows and Linux -- and in doing it this way, I have NEVER run into a situation where anything got destroyed.
Ubuntu 15.04 Mate, Mint 17.1; MS Win 8.1, Win10 TP.
Will not respond to PM requests for support -- use the forums.
