Clone laptops, computers and PC Clients Across the Network ( Free Bootable Software )

What is Clonezilla?

You're probably familiar with the popular proprietary commercial package Norton Ghost®. The problem with these kind of software packages is that it takes a lot of time to massively clone systems to many computers. You've probably also heard of Symantec's solution to this problem, Symantec Ghost Corporate Edition® with multicasting. Well, now there is an OpenSource clone system (OCS) solution called Clonezilla with unicasting and multicasting!
Clonezilla, based on DRBL, Partclone and udpcast, allows you to do bare metal backup and recovery. Two types of Clonezilla are available, Clonezilla live and Clonezilla SE (server edition). Clonezilla live is suitable for single machine backup and restore. While Clonezilla SE is for massive deployment, it can clone many (40 plus!) computers simultaneously. Clonezilla saves and restores only used blocks in the harddisk. This increases the clone efficiency. At the NCHC's Classroom C, Clonezilla SE was used to clone 41 computers simultaneously. It took only about 10 minutes to clone a 5.6 GBytes system image to all 41 computers via multicasting!
 

Features:
Free (GPL) Software.
Filesystem supported: (1) ext2, ext3, ext4, reiserfs, reiser4, xfs, jfs, btrfs of GNU/Linux, (2) FAT12, FAT16, FAT32, NTFS of MS Windows, (3) HFS+ of Mac OS, (4) UFS of FreeBSD, NetBSD, and OpenBSD, and (5) VMFS3 and VMFS5 of VMWare ESX. Therefore you can clone GNU/Linux, MS windows, Intel-based Mac OS, and FreeBSD, NetBSD, and OpenBSD, no matter it's 32-bit (x86) or 64-bit (x86-64) OS. For these file systems, only used blocks in partition are saved and restored. For unsupported file system, sector-to-sector copy is done by dd in Clonezilla.
    LVM2 (LVM version 1 is not) under GNU/Linux is supported.
    Boot loader, including grub (version 1 and version 2) and syslinux, could be reinstalled.
    Unattended mode is supported. Almost all steps can be done via commands and options. You can also use a lot of boot parameters to customize your own imaging and cloning.
    One image restoring to multiple local devices is supported.
    Multicast is supported in Clonezilla SE, which is suitable for massively clone. You can also remotely use it to save or restore a bunch of computers if PXE and Wake-on-LAN are supported in your clients.
    The image file can be on local disk, ssh server, samba server, or NFS server.
    Based on Partclone (default), Partimage (optional), ntfsclone (optional), or dd to image or clone a partition. However, Clonezilla, containing some other programs, can save and restore not only partitions, but also a whole disk.
    By using another free software drbl-winroll, which is also developed by us, the hostname, group, and SID of cloned MS windows machine can be automatically changed.

Minimum System Requirements for Clonezilla live:

    X86 or x86-64 processor
    196 MB of system memory (RAM)
    Boot device, e.g. CD/DVD Drive, USB port, PXE, or hard drive

Limitations:

•     The destination partition must be equal or larger than the source one.
•     Differential/incremental backup is not implemented yet.
•     Online imaging/cloning is not implemented yet. The partition to be imaged or cloned has to be   unmounted.
•     Software RAID/fake RAID/firmware RAID is not supported by default. It's can be done manually only.
•     Due to the image format limitation, the image can not be explored or mounted. You can _NOT_ recovery single file from the image. However, you still have workaround to make it, read this.
•     Recovery Clonezilla live with multiple CDs or DVDs is not implemented yet. Now all the files have to be in one CD or DVD if you choose to create the recovery iso file.

License:

    Clonezilla itself is licensed under the GNU General Public License (GPL) Version 2. However, to run Clonezilla, a lot of free and open source software, e.g. the Linux kernel, a mininal GNU/Linux OS, are required.

Which Clonezilla Shall I Use ?

• Clonezilla Live: Clonezilla live allows you to use CD/DVD or USB flash drive to boot and run    clonezilla (Unicast only)
• Clonezilla SE: Clonezilla SE is included in DRBL, therefore a DRBL server must first be set up in order to use Clonezilla to do massively clone (unicast, broadcast and multicast are supported)

Open Question: A baseball player's batting average is .254 (254 hits per 1000 at bats).?

3 times 52 is 156 at bats. Multiply that by .254 and you'll have your answer.

I'll let you take it from here.

Open Question: Describe the steps you would use to solve this problem.?

40mm = 8m

32mm = 6.4m

8 X 6.4 = 51.2 m^2

1 m = 1.09361 yards

1 sqm = 1.09361 X 1.09361 sq yards

1.09361 X 1.09361 X 10.89 = 13.02 $

Open Question: Can someone please help me factorize this problem?

ANSWER:
(-x - 2) * (4y - 3) = 3x -8y -4xy +6

But HOW do you get it?

Actually, the easiest way is to use one of the many factoring calculators you find on the internet. Just Google on "factoring calculator," and you'll find a raft of them, mostly free. Try a few. Pick one you like.

But, if you MUST be traditional, here are some clues for solving this by "inspection." That is a great term. It means keep guessing until you get it.

Here, you see the plus six on the end. The only way to get a plus there is to have the signs alike in the two binomials. They must either be both pluses, or both minuses.

Then you see there are a couple minus terms in what you are trying to factor, That means there is at least one minus sign somewhere. And you know already the signs are alike. So,that proves that the signs in BOTH your binomials will be negative, because you couldn't get a negative in the product AND a positive final number any other way.

So far, you have in your mental picture something like this:

(aaa - bbb) * (ccc - ddd)

Now, bbb times ddd must equal 6. Don't waste time with 1 and 6, because the 3 in front of the x tells you 6 would be impossible; it must be 3, and aaa must be -x in order to make the positive 3x in the expression you're factoring. So, keeping up with your absolutely brilliant logic:

(-x - 2) * (ccc - 3)

It's downhill from here. ccc must be some number of y's that make -8y when multiplied by -2. Duhhhh... Let's try 4y. Bingo! It works.

Checking it out:

(-x - 2) * (4y - 3) = 3x -8y -4xy +6

Okay, go make popcorn.

Open Question: Algebra question: Method explaining?

There are two distinct methods to factoring 64 - x^2:

Method #1:

Use difference of perfect squares.

Method #2:

Factor out -1 and then use the difference of perfect squares.

Both methods are correct. Choose one of the methods and factor the expression. In complete sentences explain why you chose the method that you did and include the final factored form of the expression in your explanation.

Can someone please explain what's going on in this question and provide an answer.

Open Question: anyone please answer this for me dy/dt=ky ln 200/y?

dy/dt = k * y * ln(200 / y)
dy / (y * ln(200 / y)) = k * dt
dy / (y * (ln(200) - ln(y))) = k * dt

u = ln(200) - ln(y))
du = -dy / y

-du / u = k * dt

Integrate

-ln|u| = kt + C
ln|u| = -(kt + C)
u = e^(-kt + C)
ln(200 / y) = e^(-(kt + C))

ln(200 / 20) = e^(-C)
ln(10) = e^(-C)
1 / ln(10) = e^(C)
-ln(ln(10)) = C

ln(200 / y) = e^(-(kt - ln(ln(10))))
ln(200 / y) = e^(ln(ln(10)) - kt)
ln(200 / y) = ln(10) * e^(-kt)

ln(200 / 48) = ln(10) * e^(-3k)
ln(25/6) = ln(10) * e^(-3k)
e^(3k) = ln(10) / ln(25/6)
3k = ln(ln(10) / ln(25/6))
k = (1/3) * ln(ln(10) / ln(25/6))

ln(200 / y) = ln(10) * e^((-1/3) * ln(ln(10) / ln(25/6)) * t)
ln(200 / y) = ln(10) * (ln(10) / ln(25/6)) * e^(-t/3)
ln(200 / y) = ln(10)^2 * e^(-t/3) / ln(25/6)

t = 15

ln(200 / y) = ln(10)^2 * e^(-5) / ln(25/6)
200 / y = e^(ln(10)^2 * e^(-5) / ln(25/6))
y / 200 = 1 / e^(ln(10) * ln(10) * e^(-5) / ln(25/6))
y = 200 / e^(ln(10)^2 / (e^(5) * ln(25/6)))
y = 195.05569516562951956450191705787
