Debian :: What Is The Best Way To Perform A Backup / File Transfer
Jan 21, 2010
I have a couple of Lenny LAMP servers, and a backup server. (virtual testing environment)
1. What is the best way to perform a backup? (system state as well as individual files) Although system state can also be accomplished through the hypervisor.
2. Between Windows computers, I access shared directories simply by \hostnamesharedmap or \host_IPsharedmap. Between Windows and linux i use SAMBA. But there must be a simple way to copy 2 files between linux hosts?
3. I've searched a lot, and only found people with the same question without a good answer: is there a linux equivalent for robocopy?

This script simply deletes files older than a certain age (in this case 7 days) from a certain location; I use it to purge old backups nightly, and it works as expected:
# delete backups older than 7 days
find /mnt/backup/* -mtime +7 -exec rm -Rf {} ;
The problem is, every morning I get an email with an error message something like this:
find: `/mnt/backup/subfolder': No such file or directory

I am a backup noob. My idea of backing something up is finding a big enough flash drive and copying the necessary files over.
So I really need to learn now. I'm wiping a Vista laptop for a friend to install Windows 7. But first, I want to do a whole-drive backup in case something goes wrong. It's a 100GB drive with 50GB of data.
Is it possible that I could do this via my home network or via a direct ethernet connection? I have a desktop with a 1TB drive I could back up to. Like I say, I'm a noob so I'm open to anything.
One more thing: I'd like this backup to be in a form that I can retrieve individual files from it if necessary. If everything goes right, I'll probably want to pull My Documents out of the backup and drop it into Windows 7.
Oh, and why am I asking on UbuntuForums instead of a Windows forum? Because I'm betting I'll end up booting a live CD on the laptop to do the backup. But I'm just guessing. At any rate, I'm sure I'll use Ubuntu tools, because that's what I know.

In my laptop with debian-lenny OS I have a number of ripped dvd movies some of which are about 2.5GB. I have transferred those with less than 2GB (that is the size of my usb-flashdrives) to my netbook (with opensuse-11.3 OS) with the help of usb-flashdrives. Is there any method of tranferring the larger files by connecting the two machines by ethernet cables with usb ports and using some software packages?

I want to back up an entire Linux system on a 3Tb external Western DIgital USB3 drive.
I do not want to reformat it from what it is, apparemtly NTFS.
Is there a utility that can act like a file manager like mc, that will permit me to create an ever expanding (to 320Gb) TAR file that will retain all the original file permissions. I have had nothing but disappointment with Linux backup utils with a FAT32 external drive, and I am concerned if I just try an tar the entire drive at once, with around 3 million files, I might run out of memory.

Having a bit of a issue with Debian Squeeze and transferring files to the Sony PSP..Hook up PSP to USB port and Debian mounts it..I go to drag a 125 meg mp4 to video folder..Copy windows takes about 10 seconds to transfer it..Exit USB mode and there is no video there. Go back into USB mode and look at video folder on the PSP memory stick and there is no video..It vanished. From another after copy progress closed I right clicked PSP and unmounted it..
It error-ed saying device was busy and could not unmount..Looking at light on PSP i see memory stick is still being written to..i wait for light to stop flashing..About a minute or so..Then am able to unmount it..Go to PSP video and theres the video ready to be watched. Debian isnt accurately showing the copy progress...Its showing complete when it isnt..I have to watch the light on PSP to know when it is truly finished.

Machine A holds important source data that needs to be backed up. Machine B is where the data will be backed up to.They're both Ubuntu.I want to have an automated process that allows machine A to create an encrypted tarball and copy it to machine B, without human intervention, but doesn't allow anything except copying the file over to a target directory.I thought about using a chroot jailed account, but this seems to be a pain to set up and overly complex. I really just want to be able to have machine A to copy files to machine B, via automatic cron, but I also want to prevent the mechanism that allows the copy from allowing any other actions (copying to any other directory, logging in, executing any other commands noninteractively, etc.). Also, the transfer must be encrypted (e.g. using ssh somehow).

I pulled the MicroSD card out of a non-working Android phone to backup its data onto my Debian system. My Desktop is Cinnamon and I was simply using copy/past from within Nemo. The files began to be transferred but during the transaction a dialog popped up declaring an input/output error. From that point on the card was not readable on my system.
I initially plugged the card into the computer via a USB card reader. I later tried using an SD card adapter and plugging it in my printer's SD slot. Still the system would not recognize the card. I also tried plugging the card into another Android phone. The phone could not read the card and attaching the phone to a computer did not recognize the card either. I then logged into a Windows 7 system but it could not detect it. The partition manager always showed the USB drive or SD slot as "device not connected". The last thing I tried was putting the card, with the SD adapter, in my camcorder. The camcorder prompted to format but failed to do so.
I would like to recover the pictures and videos off of the card but I am afraid that there may have been hardware failure on the card's controller. I have been searching around most of the day trying to find a solution but nothing I have tried has rendered it detectable on any system. If it is controller failure, need repairing or recovering data from physically damaged SD cards?

I wrote a script to wake up my windows machine and do an rsync backup of some of my files. I wanted to make this command a accessible through local bin so I made it executable. However the problem is that when I copies files is copies them with root permissions and i can edit or delete them. How can I set the files so they transfer with the proper permissions for my Ubuntu user?
Code:
#!/bin/bash
# Description: This script first wakes up the client machine and syncs the appropriate folders.
# Finally the script shuts down the client if it was off to begin with.
if [ "$(whoami)" != "root" ]; then
echo "Permission Denied"
exit 1
fi .....

I'm setting up a Backup & Media server, which will be running debian. I will setup a small HD or SSD/CF card for the OS, and a MD raid for the data drives.The total size of the raid will be either 3 or 4TB, depending. Now, I need to figure out what filesystem to use on top of this raid.My criteria is as follows:
1. Support for large files. I can't imagine anything larger than about 1.2TB, but the 4GB of, say, fat32 just isn't enough.
2. Robust. I don't want it falling apart on me; nothing too unstable.
3. (and this is most important): Good Undelete support. I got burned recently when a software glitch managed to rm -rf my EXT4 drive. All the file data is still there, but all the metadata is gone. I *DO NOT* want that happening with this. I want to be able to do a "RM / -RF", immediately unmount it, and then recover *all* of the deleted data. Obviously, when data is overwritten it's overwritten, but I don't want to lose all my metadata if a "RM -RF" happens. FAT-32 is the model I'm looking at: You can usually recover deleted files if anything happens to the drive.
So, what are my options?EXT2 looks like a possibility. EX4 is *clear out*, unless there's some nice utility/mode that keeps a backup of all deleted metadata etc.

I have a folder named "logs" which contains log files. I would like to have a bash script or a cron job or something like this which will check the folder continuousy and perform some tasks (for example echo "New file is created") every time a new file with pattern like "Screen.log.***" is created in the folder "logs"
Is it possible in Linux?

I am on a friend's box and we are atm transitioning from stable to sid on his box. Instead of doing the whole thing at one shot via update-manager we are doing it using the apt tools. Now while upgrading, I'm not able to update any of the perl 5.12 packages, perhaps due to circular dependencies or what. This is the error I'm seeing :-
$ sudo apt-get install perl
[sudo] password for shirish:
Reading package lists... Done

I want to add a second network card to each computer and link them together and use this second connection to transfer the files is it possible?

How do we perform offline patch management with Debian? This isn't a question about which tools to use on Debian to load the patch once it is on a CD and transferred to said offline computer via sneaker net. More, how do I keep said offline (or strictly firewalled) computer in synch?
Pardon me while I make a comparison to Solaris. I am in no way stating Solaris is better. It just happens to be my baseline of experience.In Solaris, I can download Cluster Patch Updates (CPU). So if I build a Solaris box with a CD that is a year or more old, I can download the latest CPU and get the box patched up to date, and from that point on sneaker-net patches as they appear.

I am using debian 5.04 + LXDE. In the past, I sometime encounter problems such as the distro broken after performed a full apt dist-upgrade or upgrade. Now, I am more conservative, I am using apt safe-upgrade.
I want to know are there anyway to do a better safe upgrade for debian without breaking the distro?

while trying to get a game to work on wine I was surprised to find out that the wine version that ships with sid is 1.0.1 released in October 2005. So I installed the latest release I found at [URL] like this :
dpkg -i wine_1.1.42~winehq1-1_amd64.deb
The install failed, I think because I hadn't remove the old wine version, and that's when the joy-ride started. Impossible to remove wine to restart properly. (apt-get remove libwine wine and apt-get -f install didn't) After some googling I tried this :
dpkg -i --force-depends wine_1.1.42~winehq1-1_amd64.deb
This did install the wine version I wanted, and the game ran fine after that. However the result was a borked apt-get. Tried to remove wine again with the above commands, resulting in apt-get failing to do so because it tried installing wine-unstable and reported errors similar to these : E: Could not perform immediate configuration on 'wine-unstable'. see man 5 apt.conf under APT::Immediate-Configure for details.
