Hardware and Software failures are part of Life. That is why you need to have a backup. I have already written about\u00a0backing files and MySQL<\/a>databases. You need not to backup all installed binaries (mostly software) with following tips. It will not just save your time but both Debian and RHEL distro can update them instantly.<\/p>\n

In order to reinstall or restore your installed software you need to have a list of all installed software.<\/p>\n

Task: Backup list of installed software<\/h3>\n

Debian Linux<\/strong>
If you are using Debian Linux use dpkg command to list installed software:
$ dpkg --get-selections<\/code><\/p>\n

Store list of installed software to a file called \/backup\/installed-software.log
$ dpkg --get-selections > \/backup\/installed-software.log<\/code><\/p>\n

RPM based distributions (RHEL, Fedora Core, Cent OS, Suse Linux etc)<\/strong>
Use rpm command to get list of all installed software:
$ rpm -qa<\/code>
OR
$ rpm -qa > \/backup\/installed-software.log<\/code><\/p>\n

Task: Restore installed software from backup list<\/h3>\n

Now you have a list of installed software. After installing base system you can immediately install all software.<\/p>\n

Debian Linux<\/strong>
Debian Linux makes your life easy. All you have to do is type following two commands:
# dpkg --set-selections < \/backup\/installed-software.log<\/code>
Now your list is imported use dselect or other tools to install the package.
# dselect<\/code><\/p>\n

Select ‘i<\/strong>‘ for install the software.<\/p>\n

RPM based distro<\/strong>
As far as I know RPM based distro does not offers dpkg kind of facility. But with little shell scripting technquie you can easily install all software:
# LIST=\"$( cat \/backup\/installed-software.log )\"<\/code><\/p>\n

If you are using yum, type the following for loop to install all software:
# for s in $LIST; do yum install $s; done<\/code>
Update\u00a0<\/strong><\/em>try out following command (thanks to gt):
# yum -y install $(cat \/backup\/installed-software.log)<\/code><\/p>\n

OR if you are using RHEL (RHN subscriber) :
# for s in $LIST; do up2date -i $s; done<\/code><\/p>\n

Alternatively you use following command:
# up2date -i $(cat \/backup\/installed-software.log)<\/code><\/p>\n
