Deduplication BTRFS


#1

Hi,

My Ubuntu 18.04 server has btrfs for both the temp and final storage. I would like to know if I should manually dedup the file system or is this automatic ?

If manual, I assume it safe to run duperemove at any stage ?

Thanks,

Pieter

It does whole file deduplication, so running duperemove for block/extent level deduplication may help a bit.

I think in most cases it is not going to be worth the performance hit/time.

(It seems you need to run duperemove with -d -A as parameters)

Perfect - I figured something like this - until they do it inline it’s not worth the hit :slight_smile:
