Re: Data Deduplication with the help of an online filesystem check
Hello Heinz, Hi, during the last half year I thought a little bit about doing dedup for my backup program: not only with fixed blocks (which is implemented), but with moving blocks (with all offsets in a file: 1 byte, 2 byte, ...). That means, I have to have *lots* of comparisions (size of file - blocksize). Even it's not the same, it must be very fast and that's the same problem like the one discussed here. because I just stumbled across that, I wanted to let you know about an interesting approach that NetAPP is using for its Virtual Tape Library: http://www.netapp.com/us/communities/tech-ontap/vtl-dedupe.html Thomas -- To unsubscribe from this list: send the line unsubscribe linux-btrfs in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

A very talented GSoC participant did the port as his project. A GSoC student who got employed by Cluster Filesystems to do work on Lustre, which then got acquired by Sun, who will (all things being equal) now be acquired by Oracle. :-) ZFS/FUSE is useful (I use it as an rsync destination for various filesystems that I then snapshot) but it's still got a long way to go and from what I last saw it's pretty much unmaintained now. cheers, Chris -- Chris Samuel : http://www.csamuel.org/ : Melbourne, VIC This email may come with a PGP signature as a file.
