im trying to use ddrescue to clone a dying disk to a remote machine using ssh. this is my command:
Quote:
sudo ddrescue --block-size=4KiB /dev/sda1 - | ssh user@address 'cat /data/backup.img'
it returns the error "cat: can't open '/data/backup.img': No such file or directory"
I am trying to pinpoint which component of my machine is dying. Here's what I get when I try to install Windows 7: The specified I/O operation on DeviceHarddisk0DRO was not completed before the time-out period. I have tried changing hard drives, swapping memories (running them in single and parallel), changing BIOS settings, etc. When I run a live CD with Fedora, it will come up fine but when I try to install it runs like a snail. It will never complete.
View 4 Replies View RelatedI'm pretty sure the hard disk on my FC5 system (tells you how old it is!) is failing. It's a 500GB drive and I have a second hard disk that's 1.5TB (if I remember right) as a secondary.I would like to (ideally) just migrate everything -- settings, MBR, OS, home dirs, etc., everything -- to a different drive, take out the one that's on the fritz, and reboot the system with everything as it was...just a new hard drive.
Alternatively, I figure I could remove the old drive, move the secondary one into place as the primary, reformat it (assuming there's no data I need), and then install a fresh FC version and from there, migrate data from the old one as needed. I've done this latter method before and assuming the hard drive doesn't totally go, it should work. But I'd really RATHER have somehow a "mirror copy" of the 500GB drive that just seamlessly replaces what's currently there.

View 3 Replies View RelatedI was thinking about make a clone machine. I was thinking about use a old computer that have some SATA connection. One disk is source and then I add some other disk to destination. I going to have Linux on USB stick. I have look at dd and it look nice but what I can see it only use one disk to another.
Code:
dd if=/dev/hdx of=/dev/hdy
is it possible to add more then one destination?
I know about things such as clonezilla and partimage but what I really want is the ability to make an iso from the current installation so that I can use it in a virtual machine. That wayI can develop freely without worrying that Ill crash my pc.
Also when I tried cloneziila it only chose the partitions on the local hard drive, is there software that can clone the HDD of a remote pc?
I have a 160Gb Hard drive with 3 partitions. sda1, sda2, sda3. sda1 & 2 are just under 20 GB each. the other 120 GB is free space. I have so many 40GB hard drives! I would like to copy (with dd) the MBR, sda1 & 2 to a 40GB hard drive and be able to just use that so I can free up my 160GB hard drives. Typically when I want to clone something, the drives are equal or larger than the original. I'm not too sure about this, and if I use code (show below), will I also get the MBR? #where sda is the 160gb with 3 partitions and drive sdb is a 40GB drive with 2 partitions.
Code:
dd if=/dev/sda1 of=sdb1
dd if=/dev/sda1 of=sdb1
Also, is there a way I can do this with 1 line, or have both dd operations running simultaneously?
I'm trying to clone a 2GB USB memory stick to another stick just like it (same size and brand). The src drive has three partitions, one fat, one ext2 and one encrypted (in that order). It also has an mbr. I create the clone using the following command:
dd if=/dev/xxx of=/dev/xxx bs=512k conv=noerror,notrunc
Once it's done the mbr, the ext2 and the encrypted partitions seem fine, but the fat one is slightly modified on the clone. Here is a hex dump of the (broken) clones fat partition followed by a dump of the original partition.

I often run various computers from my Ubuntu 10.04 USB startup disk. Every now and then, people get interested and want a copy of their own. Since I have installed a few extras (VLC, codecs, flash etc) on the disk, not just the out of the box 10.04, I would like to create a clone of the USB startup disk, to give away. How can it be done?
View 2 Replies View RelatedI used opensuse three years ago. Then I moved to ubuntu, because it was easier for me to use ubuntu at that time. Now, I move back to opensuse again. But I want to know how to clone the opensuse system to another hard disk. I mean I have my opensuse well, I do backup to my opensuse system and restore it to another harddisk with the same partition.
When I used ubuntu, I used a very good small open-source software, named 'Ucloner'. You can find it at ucloner - Backup/restore/clone your Ubuntu, and make Live-Ubuntu. - Google Project Hosting . It is very handy to backup the ubuntu system and restore or clone it to a new harddisk. Especially, when restoring the system, the grub can be installed to the new harddisc automatically with the UUID of the new harddisc (very amazing). But it is only for ubuntu. I am looking for a software with the similar function.
I have tried Clonezilla. No problem to do backup and restore. But I failed to boot the restored system even with the same harddisc. I know it is the problem of GRUB. Even reinstalling the grub, I still can not boot into the system.
My question is
1. is there any software that allows me to backup the opensuse and restore it to another harddisc with the grub installed to the new harddisc automatically?
2. If no software for question 1, what software or application is good to backup and restore the opensuse and how to reinstalled the grub to the new harddisc with different UUID?
3. Since the Ucloner is open-source, is there anybody having interest in change the ucloner code to fit for opensuse? I guess there should be much change, because ubuntu and opensuse are linux both?
I have win7 and ubuntu on a 250gb hard drive. I would like to move this to a 1tb drive. Is it possible to clone the entire hard drive, including the MBR? Thought about doing a disk image but unsure if this is the answer. I am using win7 64 pro and ubuntu 10.10.

View 2 Replies View RelatedI need to clone a 160GB hard drive with Linux Mint 9 (not more than 10GB used) to a 30GB SSD that is partitioned carefully (aligned to cylinder boundaries) and is currently running Ubuntu (which I wish to overwrite with Linux Mint 9). The SSD has a /boot partition, / and swap. The source (160 GB) does not have a separate boot partition. Can anyone help me fill in the steps below? /dev/sdc will be the source (160GB) and /dev/sda is the target (with partitions 1,2 and swap on 5).
make a copy of /etc/fstab from the target drive before proceeding. Ready the target partitions. Can I reuse the existing destination partitions on the SSD? Ready the filesystems on each of the target partitions. /boot is ext2, / is ext4 and swap is already set up too. As I said, all contain data (Ubuntu) that I wish to overwrite. So what steps are needed here? Do I need to erase anything (files, etc.) before the copy/clone? next, use dd to copy MBR (right?) And exclude partition table:
Code:
dd if=/dev/sdc1 of=/dev/sda1 count=1 bs=446
Mount the source and destination drives:
Code:
mount -t ext4 /dev/sdc1 /mnt/source
mount -t ext2 /dev/sda1 /mnt/boot_target
mount -t ext4 /dev/sda2 /mnt/root_target
I suppose I can leave the swap partition on the target untouched. Copy the files from the source partition to the destination
Code:
cp -a /mnt/source/boot /mnt/boot_target
cp -a /mnt/source/ /mnt/root_target
then I assume I go to /mnt/root_target and delete the /boot directory, right? Change /etc/fstab to reflect the new partitions. I mount by label. Will my partition labels be intact after this? Do I have to make any changes to GRUB? Anything else?

I have installed Ubuntu on a friends laptop. He lives in a different city, and needs to move files from one somewhat quirky 1tb drive to a new 1tb drive. He needs something that reads slowly on purpose or something like that. He also needs a gui tool. He asked me, but I haven't been able to find something for Ubuntu. maybe a custom script for ddrescue would work, but i don't even think he would like that. He is very nervous when it comes to the terminal.

View 6 Replies View Relatedextract some data off a failing drive the other day. I plugged it in, but got no response in windows or linux (partition is ntfs), but it does appear in the bios and /dev (though the hdd hung most linux liveCDs except rescue remix 9.04). I tried to analyze the drive, and found good smart data, so I figured there were just a few bad blocks in critical places. I ran spinrite against it in level 2 mode. the process crawled (40MB after 2 hours) and it updated the smart data to reflect many many reallocated sectors, putting the drive into a failing state as far as smart is concerned. so, now, in a last ditch effort I am turning to ddrescue to try to get an image of the drive. it's been running about 17 hours now, and has done several complete passes through "Splitting error areas".
here is my current output:
Code:
Disk /dev/sdb: 320.0 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
[code]....
have I done all I can? can I in good conscious declare this a lost cause? I do have an image from a prior run of ddrescue, with 826 MB of data.
edit: I resumed the task from log, and now it is reporting the err size as 9223 PB. since the drive is a 320GB, I find that a bit odd.

At the beginning everything is going fine, but after few hours the transfer rate is incredibly low. After 1/2 hour, 20 Gb have been copied.
After 1 hour, 27 GB
After 2 hours, 40 GB

Is it normal? I've also tried to use ddrescue, but I have the same problem. Is there any other tool to clone hard drive with a constant transfer rate?
