I backed up my 320GB hard drive to a file with dd:
The main idea was to be able to be able to completely replace my hard drive from this backup if necessary, but I'd also like to be able to restore individual files. I realize I could use this dd technique to backup each partition separately (there are six partitions on there), and then use the loopback device to mount those individual files, but I'd like to just have a single backup of the entire disk that can be used to both replace the disk and to restore individual files.
So, I'm imagining making this file available as some new device file, say, /dev/sdax, and then seeing /dev/sdax1, /dev/sdax5, /dev/sdax6, etc, and then being able to mount each of those. Or, how else can I get at the individual files in that 320GB backup file?
I also tried without -t. I think the reason is that I used dd to copy the entire disk, not individual partitions. That is, I used "if=/dev/sda" as opposed to "if=/dev/sda1". /dev/sda itself doesn't have a filesytem, right?
I could copy at the partition level, but I want to copy at the disk level because I want to get the boot sector so I can use this backup to replace the entire hard drive, but I also want to use this backup to restore individual files.
You don't need to use losetup to use loop devices anymore, just -o loop.
A wild guess of 16GB isn't going to have the precision necessary to hit the beginning of a partition. You should be giving it a length, too. fdisk -ul to make it display in 512-byte blocks, and then use those to figure out the exact offset.

Problem statement.
In this part of the assignment, delegates will create a pseudo-device and write a device driver for it. The pseudo-device provides a “backdoor” for gaining root access for a particular user. Instead of compiling the device driver into the kernel, delegate will create a module.... (1 Reply)
Hello everyone,
I write a program (Linux & Solaris) that will run as non-root user, but the program must have rw access to a device /dev/ipmi (on linux) or /dev/bmc (on solaris).
What is the standard way of granting such access?
Linux:
chmod on /dev/ipmi ?
suid root my program?
Solaris:... (1 Reply)
