perfect too simple to understand thank you

thank you !!

good explanation

Perfect. Thank you.

why does every video from the early '10s look like it was the 80s. Boy has technology changed us

I have spent few hours watching many people to just understand how deduplication works... and this simple video is the best video I have ever seen. You have explained the whole thing in just few minutes so any layman like me can understand. Thank you very much.

In MS world all people will have pointer to the blocks called Reparse Pointer stored in original file. And where all unique pieces of blocks get stored in server is called Chunk Store...awesome video.

thanks brah

Wow. You have explained this so well. 👍

Thats helped a lot

Very simple and straight explanation. Good job.

Great

Thanks, Nicely Explained

Awesome explanation!

You may want to watch 'Making UA-cam videos with decent audio for Idiots' first...

This is a great explanation. I just have 1 question. Why?

doesn't block change if a file within the block changes?

well explained, thank you!

i suggest a shave and a haircut.

What is deduplication?

Great explanation. Thanks but I have a question in regards to Block Level DeDuplication. If 2 guys have some song and 3 guy has different song how would block level deduplication work there. Let's say 2 of them has Coldplay - Yellow and the other guy has Iron Maiden - Fear of The Dark. How would Block Level work there.

Great explanation. Thanks

Great explanation . Thanks

Great explanation . Thanks

I know this video is old, but is very well done! Thanks! I hope it is okay that I share this to help train storage/DC sales people who need help on this topic so they truly can 'get it.' Will always make sure you get credit for sure! Great work.

Great! Thanks

Clear and concise explanation - thanks

Thank you. Now I have more understanding.

nice

great explanation.

We understand file level but In block level deduplication, if any 1 will change his data then how it will get store in data center ?? and if no two people have same data then ?

That was Bad Ass.... great explanation and summation

Thanks for sharing this info...

Well done. Thank you!

Thank you very much!

You keep a table transparent to the user that wants to ignore that does the logical (what you think there is on the bup storage) and physical (what you actually have on the storage). Let's take the last case from the vid. you think you have 1234, 1245, 1235 but in fact you have 12345. The mapping table might contain: Block 1 represents 1st, 5th and 9th logical blocks. Block 2 logically represents 2nd, 6th and 10th logical blocks.... Block 5 represents 8th and 12th logical blocks.

hi! The only thing you dont tell: How does deduplication on block data knows where each block goes? I mean, 12345 ist just a row of number for 1) different users and 2) different blocks; so it's not Me=12345M; Ted=12345 ... so, how does Deduplication knows where each block goes? and how much space does this information require compared to the origin-block information? Hope you can explain that, maybe either in a video or with a comment, THANKS!

well done. that is understood even if your non-technical like me. thanks

Thanks, Well Explained.

This helped me so much! Great job!!!!

grossaly underestimated file deduplication: forgot Rabin fingerprints, chunking files?

Nice job

Nice work. Any recommendation which backup software is good/superior than others for block level dedupe?

Awesome, Summation! Im in the process of selecting a SAN solution and this simple video added a great piece of knowledge to my overall understanding! Thanks!

Thank you. Well done.
