General :: Copy Remote Files On Nfs Without Round-trip?
Sep 20, 2011
I have a large amout of data (several GB) on a remote drive, that is transparently mounted via nfs. I'd like to copy these files into a subdirectory of where they are already residing, so everything stays on the same physical disk. For that reason, I would like to prevent an unnecessary round trip over the network.
It seems that cp files* subdir does the naive thing and reads all the data into memory and then writes it back. Is that true? Is there a special command that does the actual copying entirely on the server the disk is physically connected to?
Is there any tools in linux same as "http-ping. This tool shows for any request : 1-The HTTP return code (and its brief textual description) 2-The number of bytes returned by the server (excluding headers) 3-The time taken to complete the request (i.e. round-trip time)
I would like to copy several files from a remote machine. This archives are contained in different folders and their name have a commun caractheristic (also the folders).I have tried something like that:
ftp open machine@ prompt %to get into the non interactive mode
I regularly need to copy files from a remote computer to wherever I am working. I've ben looking into alias and the .bashrc (or .profile in the remote computer - mac) Can I use scp in these files? I've tried:
Code: alias='sch usr@location:' then when in the local terminal:
Code: sch path/file . But this doesn't work.
Better would be copying when logged into the remote location, but I haven't figured that out in terminal yet, let alone an alias for it. Hopefully it'll be a quick solution!
I would like to use the command rcp to copy file from remote server ( linux ) to local pc , what is the command ?the remote server name is lnx_srv , the path is /tmp/ora_file1.txt , the linux login id is ora_usr , the .rhosts have released to ora_usr the localhost pc path is c:OraI read the help page of windows , tried the command rcp lnx_srv.ora_usr:/tmp/ora_file1.txt c:Ora , but not work , the error is "rsh: can't establish connection" , Can advise what is wrong ? what comamnd should i use ?
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)?
Allright, I made a simple script that tarballs my SQL databases weekly and saves them to a backup harddrive.If possible, I would like to have the backups uploaded to a remote server for storage. But, I must have the script delete the previous upload for size contraints.I can only use rsync, scp or sftp. Haven't used any of them really before... Here's my basic tarball-backup script:
Code: #/bin/sh # Dates the new tarballs of current builds. DATE=`date +%m_%d_%Y`
I need to back up a fold on a remote machine to my local box; the remote hd does not have enough space archive it, neither does my local box. I know there's a cantrip to pipe scp through gzip (or similar), but I don't remember the syntax.
i am using dolphin 1.5 in kde 4.5.2. whenever i try to access movie file from remote samba server. dolphin copies the movie file to somewhere in local hard disk. so, i have to wait until a big file transferring complete. i know that it happens when i open .avi using mplayer. if i open the same remote file with kmplayer, it will player immediately instead of making local copy first. however, kmplayer is very slow and sounds and video stream breaking up, (i am sorry i do not know right english expression for this) i suppose this is not related to mplayer configuration. this seems to be dolphin problem. can i make dolphin to stop copying samba share to local disk and play instantly? there is a video in videos. it is comparing how dolphin and nautilus act differently when i play remote samba share movies.
When i installed ubuntu. I made a seperate partition so that i could copy an ISO image onto it of an up-to-date version of ubuntu. I wanted to then boot the ISO up so i could install the version that way.I've already tried doing it through the update manager but it'll download, almost be done with installing and it freezes on me. so i figured this would be easier. However i do not know how to gain access to the other partition to copy the ISO image.
I have many files and folders in my source folder. I want to copy some files and folders from that source folder to destination folder. What should be require to given with the "cp" command?
I want to use awk to list all the mount points, disk size and space available. Now I have all that info but I want to round the totals, so there is no delimiters, how can I do that?

I have a 160GB harddrive which I installed a F12, would like to upgrade to a bigger drive, but I hate to have to re-install everything.
Recommend a good disk copy utility? The utility should be able to not only copy files, but boot sector and everything. So I just need to make a copy, change my BIOS to boot from the new drive and run everything as before.
just installed ubuntu couple of days back on my netbook. I am still a beginner, enjoying my adventure exploring ubuntu. I have another desktop which runs on XP. I am able to access XP shared folders through my netbook(linux). However, i wanted to copy files from XP infact folders using TERMINAL in my netbook, not copy and paste using my mouse. Are there any commands for it?
First of all, I searched the forums but I couldn't find anything- I don't want to be the poster who posts something that's been solved 14 times already Anyway, primary question first and then "why" below- I was wondering if there was a quick way to hibernate Ubuntu to Swap -> boot to Windows 7 and work -> Hibernate Windows 7 -> boot to Ubuntu and work, repeat until Windows glitches
I have, new Acer Aspire: i3 370M 4GB RAM 640GB HDD as follows, from inside to outside: X GB 3 Primary Windows partitions, 125 GB unnallocated, 50GB /home, 6 GB .boot, 4 GB SWAP
Ok, why would I want to do that? I ask because while Ubuntu boots fast at just under 1 minute at the end of my hard drive (90Mbps, I had it install from "end" when I partitioned the boot file), Windows boots slowly at about 2.5 minutes on the inside of my drive (23sh Mbps). To be able to switch between them would be useful for iTunes, ProEngineer, Matlab, and other stuff that is Windows based. Windows boots much faster from hibernation. I love Ubuntu, the speed and simplicity and the actual FRIENDLY atmosphere (what a concept WINDOWS) But I find myself needing to do some quick editing in Windows, then I can go back to my business on Ubuntu. Is there some kind of selective boot managing like GRUB that I can bring up after telling one to hibernate? Because once on SWAP, it should hold relatively indefinitely until I return, right??
Any ideas??? It sounds like some clever Terminal coding could manage the Linux side of the booting, but Windows might have to be tricked into a selective boot..
I'm trying to copy files to the /var/www folder on Ubuntu 10.04. But I think I don't hava the permission. How can I do this? Maybe I have to set the rights permissions.
Possible Duplicate: Linux equivalent to robocopy? I have two websites - one is basically a development version and the other is a production version of the same site. So I'd like to be able to merge the changes made to the development site based on the modified date of the files. Is this possible with the 'cp' command?
At the moment I'm using:"cp -ap . /destination-folder"to copy everything from the folder I'm in to another folder.That works.Is it possible to cp everything except:folder1/folder2/in the current folder I'm in?

Now I have learned creating partition in linux (ubuntu), well that's an achievement for a newbie. The next thing that I want to know is, how can I copy the contents of a partition to another partition. Like if I want to backup its content to a new partition that Im going to create.
my internet used to work with no problems at all, but then I went on vacations to Spain, and since I came back to france, my computer doesn't want to connect to internet from my house.It doesn't find the wireless connection and now not even the regular wire connection works! I have to admit that while I was in Spain, the computer aked me to install some updates and I did! now, I just have no idea of how to make it work!
I'm trying to copy a list of files except the files which has ".log" in the filename to another folder.I can run it correctly when I am located in the Source folder, but not when I am in any other location.cd /home/me/Sourcels /home/me/Source -1|grep -v "^.*log$" |xargs -n 1 -iHERE cp -r HERE /home/me/DestinationHow can I indicate both Source and Destination Folder?
