Iso, disc backup, dd, disc to disc backup, UEFI, unmounting?,
by Ana Hartley from LinuxQuestions.org on (#5G18M)
I thought after recently installing grub Dual Boot with Ubuntu on a system where I had already got windows 7, I had better make a backup of the entire drive(both OS's) using maybe "dd" command, pref. to another disc, as it's pretty big: 500gb, 330gb of which is in use.
Nothing could have been more complicated, it seems, as dd requires AN UNMOUNTED DRIVE or disc, or maybe partition if I do it partition by partition.
What an ordeal, as I don't have another computer, and unmounting seems dangerous, and prob. cannot be done with a running system.
Could I unmount and remount a running system to just make "read-only"?
Am I supposed to unmount just the partitions, one at time? I have an extended drive,based on one particular partition, which Ubuntu kindly made on default-type install. Are there any other options for backing up entire system(s)?
What should I do? I am.loathe to play around with partitions as am not competent yet, and don't fully understand UEFI booting, or NVRAM.It seems in UEFI the UEFI does most of the os system detection, and boot manager.
Any information would be good, or decent, rigorous links! Thankyou so much in advance, you guys do amazing jobs, maybe one day I can be a forum answer specialist!
