is there any working solution for deduplication of data for centos?
We are trying to find a solution for our backup server which runs a bash

The better option for ZFS would be to get a SSD and move the dedupe table
onto that drive instead of having it in RAM, because it can become massive.
What's 'massive' in dollars these days?

Les is right, I stop the server, take the snapshot, start the server and
do the xdelta on the snapshot NSF files.

Sorry for the top posting.
Dedup is just a hype. After a while the table that manage the deduped data

The website looks promising. They are using a thing called SPL,

Rdiff-backup might work for this since it stores deltas. Are you
