In my previous post, we saw how to create backup using tar command. We learned how to archive and compress a directory into single file. But also we can use same tar command to archive and compress multiple directory. To do that, instead of sending single directory as a last parameter, you have to send multiple directories as a <directory_to_be_compressed> parameter separated by white space. This command is very useful when you want to combine multiple directories into single archived file and transfer over from one location to another one. Now in following section we will discuss about that command and how to do incremental backup using tar command.
For example, use following command to archive home directory of multiple users.
umesh@umeshupreti.com # tar -cvf allhomedir.tar /home/umesh /home/guest /home/upreti
Above command creates a backup of three user’s home directories: /home/umesh, /home/guest and /home/upreti. Generally backup is done in daily basis and if your home directory is large enough then it may take some time. That is the main reason here I am talking about incremental backup system. Read more…

The command-line utility tar is probably the most popular and easy Linux backup utility. This command line is used to create an archive files for backup. Linux command tar stands for tape archiver.

This command not only archive files but also can compress files using one of the most useful file compressing utility bzip2 or gzip. Compressing file and archiving it into single file not only save your server space but also make it easy to transfer file from one location to another over network. In this section, you’ll learn how to create tar archives and how to extract files from them. Read more…
