# Archiving and compressing data files tar

We will briefly discuss the use of archiving and data compression via the tar command.

## Archiving

To archive data, we use the command tar -cvf, like this:

nadir@ipowerht:~/Desktop $ls -al total 73796 drwxr-xr-x 8 nadir nadir 4096 2005-10-14 18:56 . drwxr-xr-x 37 nadir nadir 4096 2005-10-14 18:49 .. -rw-r--r-- 1 nadir nadir 72265250 2005-10-14 00:30 archive.tar.gz -rw-r--r-- 1 nadir nadir 69 2005-03-20 17:22 .directory drwxr-xr-x 2 nadir nadir 4096 2005-04-08 00:10 evian drwxr-xr-x 2 nadir nadir 4096 2005-10-14 18:56 muzik -rw-r--r-- 1 nadir nadir 18652 2005-10-14 14:21 pagerankstatus-0.9.5.xpi drwxr-xr-x 2 nadir nadir 4096 2005-05-16 18:08 poster -rw-r--r-- 1 nadir nadir 1517514 2005-05-16 17:18 poster.tar.gz drwxr-xr-x 2 nadir nadir 4096 2005-05-16 18:03 poster.tar.gz_FILES drwxrwxr-x 10 nadir nadir 4096 1970-01-01 01:00 Sauvegarde -rw-r--r-- 1 nadir nadir 1686 2005-10-13 17:12 sources.list drwxr-xr-x 4 nadir nadir 4096 2005-03-27 19:13 these -rwx------ 1 nadir nadir 1632848 2005-03-19 22:53 these.tar.gz nadir@ipowerht:~/Desktop$ tar -cvf muzik.tar muzik

## Archiving and compressing date files

When the data volume is important, we sometimes want to compress the data using the gunzip utility, we use the command tar -cvzf

## Conclusion

All of these commands are very useful for backing up your data file . Do not to forget them !
