@11:04 "So just like an mp3 takes a music file off of a CD and makes it smaller" Please note that the .mp3 format, in pursuit of saving space, discards (often over 50%) data. The thought behind .mp3s is that the listener will not hear (will not notice) what is missing (similar to if you removed X number of frames from a video -- how many would have to be removed before you would notice?). So .mp3s use a "lossy" format. Whereas, "tar" uses a lossless format (tar throws away nothing -- 100% of what you put in gets saved).
Although zip and unzip are available for Linux, I believe that they do not maintain file permissions. If the files you are compressing are such that their permissions do not matter, then zip and unzip should be fine to use. Otherwise, use "tar", which will maintain your file permissions. Cheers!
@Jason, how to convert file.tar.gz to file.zip? Because 99% folks are using windows. Is there any API as zip in Linux or we can convert from tar to zip in Linux?
Data Centers. But probably not the type that was pictured in this video. Today, LTO is the standard type of tape medium (there are many versions, each of which run at different speeds and hold different amounts of data).
Your videos are so easy and well explained, they are still valid even after 8 years! I wish you created more of them.
good content, our prof linked your videos to help us learn archiving, props!
Excellent videos. Need more publicity to reach a wider audience. Please create more tutorials.
thank you, I come back to this video to quickly refresh the concept :)
your linux lectures are the best! i will watch all of them :) thank you for sharing

can you create an empty archive file and just put it into one of your Directories or does it have to have data ??
that was very cool explanation
what happens when I don't use the -f parameter with the tar command?
I tried of course and I got some weird output full of numbers on the terminal
-f is like the name of the file we want to have
@@Denbl-du7mr thx
@@Denbl-du7mr Might output to terminal when no file name specified, guessing.
Awesome

Thanks so much!
Who uses tape drives?
