Ubuntu :: Take Copy Of Installed Packages And Backup System?
Dec 7, 2010
Every time I install ubuntu I have to reinstall all the software from the software center and so. Now I already installed all software I need for this moment. Is there a way to take source files of those (installed) packages and save them some where else in order to reinstall them if i needed next time without need to INTERNET connection ???
Another question I wanna know about: How can I take a backup of my system as whole in order to get back to it if some problem happened. I used to use Acronis True Image and its alternatives to make a disk image. Is there is some thing similar in linux ?? is there better options ??

I'm currently running 9.10 and am anticipating upgrading to 10.04 when it is released next week. I am however, running several packages from PPA's that were simply not working well at the versions included with 9.10 (I know specifically the 64-bit version of Flash and Wine are setup this way).
Since these installs are out of the scope of the official Ubuntu sources, how are these handled when I upgrade? More importantly, since some of these packages were just installed as a temporary fix until 10.04 came out, for some of them I'd like to remove the PPA version and reinstall the default version (since for several of them the 10.04 version has caught up to where it needs to be). Is there any way to identify all packages installed from PPA's on the system?

I just installed CentOS 5.4 Final on a 64 bit system. After install, I found a lot of 32 bit packages are also installed. Is it necessary for a pure 64 bit system to run (let's say, I will never want to run any 32 bit app on this system), or is it something I could have avoided during install?

Install One :
Installed Debian Squeeze onto my laptop using the netinst cd. During installation, I did not have access to the internet and installed "Standard System" during tasksel.
Install Two :
Installed Debian Sqeeze onto my desktop using the same netinst cd. However, this time I had connected the desktop to my router during installation. Similary installed "Standard System".
Both system later installed with KDE and working fine. Noticed that immediate after installation of the "Standard System", my desktop had more files installed eg. the exim package. Why the extra packages (eg exim) are installed? Are they actually required?

I have a dead system that was running Debian Linux (lenny). I can boot into emergency mode, but nothing else. I will likely have to reinstall Debian. I've read lots of things online about how to get a list of currently installed packages. Which is fine and dandy if the system is working and I can log into it. I'm basically wanting to extract such a list from a hard drive containing an installation I can't log into normally. I can access the filesystem just fine, and nothing related to aptitude has been damaged.

If I do System-Preferences-Personal File Sharing it tells me that I can't enable sharing over the network because "the required packages are not installed on your system". It doesn't tell me WHAT packages I need to install!

I have my home network set up like so. My router has 4 ethernet ports so I have 1 hooked up to a network hub where I have 2 computers running windows xp and 1 running windows 95, on my other router port I have a desktop using ubuntu 11.04 and I have 2 windows 7 laptops and 1 ubuntu 11.04 laptop connecting wirelessly. All of the computers can see each other in my network map except for the ones running ubuntu. I can successfully ping every computer on my network from every computer without fail (even the ubuntu ones). The weird thing is that my ubuntu computers can see and use files from all of my windows computers but still nothing can see the ubuntu computers. I have set up samba to no avail and when I open file sharing and try to enable it on ubuntu it comes up with "this feature cannot be enabled because the required packages are not installed on your system." I have done clean installs of ubuntu 11.04 and 10.10 on both ubuntu computers and kept them up to date but the same problem persists. I have tried to do the same steps above with all of my computers wired but still nothing.

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.

Is there a way using dpkg or apt-get to segregate user application packages from system packages? What I envision is an /apps directory structure that can be the install target for selected packages so not to "clutter" the storage areas for the system administration files/packages - maybe even with permissions set so that (a GROUP of) users could install packages on an Ubuntu server w/o SysAdmin guidance. This could also allow 1)system upgrades with or w/o including these packages, and 2)the sharing of /apps (via NFS) among common Ubuntu systems. Is this doable using the dpkg or apt maintenance tools?

1. when we install package and run update manager, are all the packages stored in /var/cache/apt/archives ?
2. let's say i make a copy of all the packages i installed and from update, store them in a backup drive. How do i make a freshly installed Ubuntu to copy/use these packages instead of downloading them from the internet?

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.

Mintppc has a nice little backup tool for making a backup record of all the packages you have added since the initial linux install. Does Ubuntu or anyone else have such a backup utility? It would be nice to have it all the packages documented somewhere in case I ever have to reinstall and figure out what packages I installed.

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
dd if=/Users/jack/Desktop/usb_copy of=/dev/disks3s
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 just got a 2TB drive with the intention of backing up multiple Ubuntu machines to it. What would be the best way to do this, keeping ease of restoration in mind? Should I just copy each drive image to the BU drive, or use a utility like Back in Time?

I will like to get a text file of the packages that need to be updated in my ubuntu 9.10 machine.
The thing is that I previously did an update an its made my Zoneminder setup fail, and now I want to double check prior to doing a full upgrade.
If anybody could provide me with a command in the terminal or event synaptic, which could help get a printout or export to text file, the current version in my system with said that need to be updated to, for every packages.

I want to backup my server that godaddy is hosting and install it on my linux system at home. In other words I want to have a clone of my server at home, like what timemachine does on mac (carries files and programs from one mac to another to make a clone).
How do I do that? I create an image file an iso file? or what? How?
I want to do this incase my server burns up over there. I don't want to reinstall all the programs and do the set ups manually again.

I have just installed Debian Lenny and was trying to upgrade the installed packages from the packages.debian.org site. when i asked synaptic to add the downloaded packages the would not appear, but when i checked the .xsessions file there are entries saying that the packages were being ingnored because they were either different versions, the MD5 did not match or even "can't find pkg". i have to use the local library to download the packages because i dont have an internet connection at home.

I would like to copy few myDSL extensions/plugins to dsl.isowiki says: "When a new version of DSL comes out, just copy your additional applications to the root directory of the CD-ROM.

How to make a backup of installed applications?
In the answer there was some program which would create a file listing all installed apps and store it in /home. On updating the OS or re-installing, the file would be used to re-install all apps listed.
