imaging software Flashcards
what is formatting a machine with an image of another machine called?
imaging a machine
How does a disk cloning tool work
makes a copy of an entire desk and allows you to back up a current machine or set up a new one
what is the benefit of cloning over standalone installation media
you can also install settings and folders you might need
what is zillow
a disk cloning tool. open source, can be used to back up and restore a single machine for many machines simultaneously
what is semantic ghost
a popular commercial imaging tool
what is disk to disk cloning
you connect an external hard drive to the machine you want to clone, like an external hard drive dock.
What are hard drive docks?
External tools that look kind of like toasters
what does dd do in linux?
copy files, may also clone drives.
when cloning a drive in Linux, what is the first thing we want to do with the connected drive?
make sure it is not mounted by checking
umoutn /dev/sdd
what dd command will you use to clone a drive to an unmounted sdd in linux?
dd if=/dev/sdd of=~Desktop/my_usb_image.img bs=100M
This says: I’m gonna copy the contents of /dev/sdd, which is the usb drive, and save it to the desktop in an image file. once the image file is saved if we open it up we can see the exact same contents as we see on the usb drive.
when is disk cloning often used
when an enterprise company purchases a large number of identical computers
what do you do when you have to deploy lots of computers?
select a new computer to install and configure needed items, OS, files, utilities, tools, network settings, software, drivers, firmware, etc. Then, make a clone of the hard drive for that configured system and deploy it to the new computers. keep a copy of the original disk in case reimaging is required.
what can be used to test new software and configurations before applying the updates to similar production systems?
cloned disks.
uses for cloned disks:
system migrations, data backups, disk archival, copy of a hard drive for investigative or auditing purposes.
What are some uses beyond deploying operating systems for clone discs
system migrations data backups dis archival, making a copy of hard drive for investigative auditing purposes
what are machines that can make identical copies of hard drives
hard disk duplicator
how does a hard disk duplicator work
the original drive is inserted into the duplicator machine along with one of more blank hard drives as targets. disk duplicators can have anywhere from a single target bay for limited disk cloning of to one hundred target bays for industrial use. drives are not blank the duplicator machine can wipe the drives. the target drives usually need to share the same characteristics of the original drive. the targets should also have the same or greater storage capacity than the original
what sort of interface does a hard drive duplicator potentially have
else interface or a management software HTML interface which can be accessed over a network or directly connected computer or server
how do most duplicators copy data
sector by sector
what does cloning by disk cloning software allow
the original and target media can be different media from one another. a hard drive can be cloned from an ide drive to solid state drive a city ram DVD removable use drive cloud based system or other storage media.
what is the most efficient method for cloning servers and workstations
VM cloning
whatdoes software cloning support
fold is copies including the operating system all setting software and data or copies of select partitions of the drive which is useful for data only or operating system only copies
what are a few examples of disk cloning software
