General :: Backup - Any Copy And Verify Command In Ubuntu?
Dec 5, 2010
I back up all my digital photos to a couple of places. I've been using the cp command, but--given the personal value--have started to wonder if there's a more reliable way. I'm no stranger to Linux, Bash, Perl, etc., so I could write something to copy and compare md5 hashes, but I was wondering if something already exists (reinvention, wheels and what-not).
Most of my googling for copy and (verify|valid|check|hash|confirm) turns up rsync. However, as far as I can tell, rsync only uses hashes to see if a file needs to be updated. It doesn't perform a hash comparison afterward. For this use, specifically, the files are binary and typically 8-10MB.
I am in the process of cloning a HD. Before I wipe the original drive I was wondering if there was a tool to create something like a md5 hash of the entire drive to verify that I have an exact copy. It does not necessarily have to be an md5 hash and any command line BASH options would work for me as well.
How to copy a Read-Only file in Linux and make the copy writable with a single cp command in Linux (Ubuntu 10.04)? The --no-preserve and --preserve seemed to be good candidates, except that they should "and" the mode flags, while what I am looking for is something that will "or" them (add +w mode).
More details: I have to import a repository from GIT to Perforce. I want that all Perforce depot files are Read-Only (that is how Perforce was designed), while all other files that were derived/copied from depot files are writable. Currently if a Makefile tries to copy a Read-Only file then the derived file will also be Read-only. This leads to build-errors when cp tries to overwrite Read-Only file second time. Of course the --force is a workaround here but then the derived file is also Read-Only. Also I do not want to mess with "chmod" after each "cp" command - I will do that only as the last resort.
I installed Ubuntu 10.04 on a usb stick in persistent install mode. So I could boot the laptop or my desktop computer with the stick, at boot time. Once I needed the 8GB stick for another purposes so I thought about coyping it to my desktop doing from mac os x: dd if=/dev/disks3s of=/Users/jack/Desktop/usb_copy
Now I am trying to do the opposite, after having used the stick, which was formatted to NTFS, just doing
but although I can see that almost of the files are there, I can not boot again. IT is also strange the the file permissions are kind of strange, something like _user
I have an account in university on Linux machine with 10TB of free space accessible via SFTP. I would like to backup my Windows 7 x64 laptop to university. Currently I am using rsync+cygwin, but backup is pretty slow (without shadow copy) and I hate console window appearing every day on my screen when I login.
So I am looking for something like Windows Backup but with support for SFTP. Combination of tools will work too.
I'm new to Linux and I am currently using the Ubuntu distro. What I'd like to know is whether there is a program or command I can use to back up my hard drive with Ubuntu? I have an external drive that I can use for this purpose but I don't know how to set it up for Ubuntu or Linux generally.
my laptop has a 320 GB hdd which is dual booted with win 7 and linux mint.If i remember i dont think i am using the entire 320 GB from the hdd,may be around some 200 GB.If i use a DD command and back it up to an external 500 GB hdd,will it back the entire 320 GB or only the data which is of 200 GB ?
I want to have a full backup of my HDD ,incase the hdd fails in laptop i can mirror it to a new hdd from the external hdd.
For example, if I type ':pwd' to get the current working directory, I can select the text in gvim but I can't figure out how to copy it to the clipboard. If I try the same in console vim, I can't even select it with the mouse. I would like this to work with all vim commands, such as set guifont to copy the guifont=Consolas:h10:cANSI output.
I made a backup copy of my system before encountering a problem. Now I want to install Ubuntu 11.04 and use the system backup, but I can't copy it to disc because it is just over 10 Gb.
I have to transport a lot of files from one pc to another (both Linux). I would like to use scp for that, but scp only allows for transferring one file at a time. How can I do this?
I have No possibility to use rsync or any other protocol No possibility to use passphrase free certificates (but have a certificate with a passphrase) A list of files to transfer and a list with the destination path of the files on the other server The files are spread out over a lot of directories, and not all the files in the directories I want to copy If possible I would like to gzip and ungzip transparently to save bandwidth!

Imaging-copying a working remote share on WindowsNT to a local Linux disk target is needed . Is that possible with dd command(how if remote share is connected as smb://ipnumber/share) and do you need root privilleges on local and remote machine for that?Perhapson source machine:dd if=/dev/hda bs=16065b | netcat targethost-IP 1234on target machine:netcat -l -p 1234of=/dev/hdc bs=16065borrsh 192.168.xx.yy "dd if=/dev/sda ibs=4096 onv=notrunc,noerror" | dd of=/dev/sda obs=4096(any difference to dd/privilleges if you use it as windows dd version since remote is running windowsNT)?

I'm trying to truncate a postfix Maildata directory for one of our users. I want to be able to move any files older than <n> days to a new location, but also copying the relevant directory structure. This should be doable in the one comman. I've used find to locate the files, and mv to move them, but I can't figure out how to build the directoryt structure on the fly in the new location.
