Linux: Snippet – Backup using Tar and gzip



As a programmer i have to make multiple revisions of a project on a remote site. Getting things wrong and messing up the files tend to happen more often than I am comfortable with. Fortunately, making quick backups in linux is a breeze. You can either make a folder and just copy your existing files via recursive cp command or; archive it using tar and gzip. Personally, I prefer archives since they tend to be smaller and easy to manage.

Install tar and gzip
You can be hardcore and download the source for tar and gzip and recompile them.
 
Or you can use apt-get or yum(Yellow dog Updater, Modified ? — weird name ) to do it for you.
yum install tar
yum install gzip
Sample commands
Archive a folder ( -c means create )
tar cvf -  folder | gzip > archive.tar.gz 
Archive a file
tar cvf -  filename | gzip > archive.tar.gz 
Archive files
tar cvf -  filename1 filename2 | gzip > archive.tar.gz 
Alternative format (-z means use gzip to compress)
tar cvzf /path/to/dir/archive.tar.gz filename1 
tar cvzf /path/to/dir/archive.tar.gz filename1 filename2 
Extracting (-x means extract )
tar xvzf /path/to/dir/archive.tar.gz 
There are other ways and tools to make your archives. But we’ll continue with that some other time. For the really lazy, I’ll make a bash script that uses tar and gzip in a later post so watch for that.
I hope my article helped some newbies out there. Mabuhay!
